all right so today I'm going to be going over one of the most miserable most [ __ ] repairs that there is on a MacBook motherboard which is replacing the SMC there are many things that make this [ __ ] and we're going to be going over them in real time uh so one of the reasons that I haven't done one of these videos is because most of the time that I have a board that needs SMC replacement it looks something like this like yeah I mean there is a damn good chance that there are other things wrong with this board but usually when you have a board that needs an SMC replacement it's just it's just [ __ ] to the point point of like everything being destroyed which is you know again very much so against my 20-minute rule so I've already removed the SMC from this board I'm not going to be able to show you that part of the process but you are going to see me take the SMC off of a donor board take that SMC from the donor board and put it on this board and we're going to see what happens so the first reason that this process is a complete pile of hhip is that I cannot get new smc's I can get new smc's with no programming sure but what [ __ ] is that going to do me I need to take smc's that have programming already on them I have no way of programming this SMC with the original firmware so what I have to do is I have to take boards that look like this that have holes in them that very well may have been destroyed because of a bad SMC and take the SMC off of this piece of ship to put it on here so let's start with that part of the process again this this completely sucks because I don't know if this SMC I'm removing even works I'm going to go through a lot of trouble a lot of misery to get this SMC off of here and again this SMC may actually be a complete pile of [ __ ] who knows but that is that is what it's like to service Apple products as a third party repair center hell if we can be allowed to program this hell if they're going to give us any information how to do it cuz there is information there there are connectors on the board where you can simply plug something in here and just program it but we going to get that information that software that support no way in hell Apple would never want people to know how to actually service their own product that would be a that oh dare no no no we have to do this [ __ ] and that's the thing like you're not stopping people from fixing this stuff a 26-year-old College Dropout who can barely pass a CPR AED exam is still going to be doing this [ __ ] and filming it and putting it up on the internet for people to see so that they can do it themselves as well like you're not stopping people from doing anything all you're doing is making it more of a pain in the ass and you're causing more people to hate you so the the other reason I haven't done one of these videos again a that board it may not work for many other reasons than the SMC and also I don't know if the SMC I'm even putting on it is good and I like to show you that what I did worked I like to show you that the the result of my work is a is a product that works I always tell you if somebody cannot show you that the product works that there's no reason to list of them because they're showing you how to do something that just doesn't work but here I'm just going to break that rule I I CU there's no video on the internet that even shows you how to remove an SMC how to reball an SMC how to do any of this stuff and that actually goes through it in depth and detail there's none at all that even show you without the depth and the detail you can't even find an SMC replacement video where they're doing it with techno music so I'm going to do it and even if it doesn't work again troll is going to troll you can laugh as much as you want but it is what it is also most of the time that this doesn't end well and the boards that I do this on are usually boards that are completely [ __ ] and the boards I'm taking the smc's from look something like this okay got the SMC off now the first thing to do is to clean this thing so I'm going to take this clamp that I got over here this is my clamp and we're going to put the SMC inside of the clamp now that what I want to do is I want to clean it so I have this clamp that's actually kind of made for this size chip I'm I'm pretty certain that I got this from David at Advanced reworks I'm 99% 99.999% certain that this came from David so if you need one of these things hit David at Advance three works up then ask him for one of these I just got flux on me BL all right so I'm going to wash my hands to get that [ __ ] off of my fingers and before I do that you can take a nice look at what this looks like pretty isn't it freaking flux ah so the first thing that I want to do is I want to Wick the solder off of the pads but what I want to do is I want to make sure there's no le leadfree solder on there and also that there's none of that oxidating junky nasty [ __ ] on there that's going to keep the pads from being able to be tined so what I'm going to do is I'm going to actually try to Tin every pad right now with my with my leaded solder over here and I'm going to show you I'm going to talk about what I'm looking for as I go this looks like some dry gunked Caked Up crap come on get hot just turned on the Hackle okay it's hot so what I want to see is that I can get solder to stick to every single pad so first I'm just going to make a quick walk through to get rid of any of the lead free junk now it may look like the repairs that are ripped that's the first thing that you're going to think of if if you have if you're not used to working on stuff at the scale but what you're going to see is if I scrape a little bit you're going to see that that the pads get tinned so I'm going to focus a little bit on each pad so for example the one all the way on the upper left looks like a ripped pad right I'm not going to scrape hard because if I scrape hard I destroy it but I scrape a little bit and then I solder and the one under it scrape a little then solder uh scrape a little then solder so what I want to do is I want to make sure that every single one of those pads is prepared to accept the balls that I'm going to be putting on it cuz there's no point to reballing this chip if the pads don't accept the solder because they're just junk and you know so a little bit and I clean it with this because the iron itself is hot so the iron being hot is you know it's going to be better for removing dirt than if it's cold it's a piece of metal that I can scrape with I have good control over it I'm used to using this so I know how much pressure I'm putting because it's an instrument that I use all the time every day so I'm just going to go through here and just kind of try to make all those pads work again the other thing is this solder has flux inside of it so flux is also good to get rid of oxides and dirt and other junk so what I want is as I'm scratching that stuff away I don't want it to just go back onto the pad I want it to get sucked up into that solder ball that I'm making and then I just Wick it off of the iron and then I clean it off of the iron and so I have a solder ball that's probably filled with old flux and dirt and I just wash that away okay going to so this is not actually putting balls on it all I'm doing is tinning the pads because I want to know that each individual pad has the ability to accept solder this is an important part of the process this is not very important with Graphics chips that have large pads or CPUs with 75 mm balls like the old core2 Duo ones but the SMC it is because I don't know this chip is just designed to be a [ __ ] I really there's no other way to put it this chip is a female dog a very loud barking obnoxious female dog of chips we just go through we go through for after a while that Rosen flux gets nasty So eventually I am going to have to clean it off I like to try to get this done before doing a cleaning just to stay kind of efficient with it there's one pad that's not tinning here we go I'm getting somewhere okay so that pad I was actually I was very close to the saying that it's ripped let me just grab another board get another SMC but I was able to scrape away at it it wasn't ripped again you're going to think that a lot of these pads are ripped they're not ripped they're just really really [ __ ] dirty so keep that in mind so at this point I've proven that just about every single one of these pads can accept solder and since I've done that now I'm happy that I can go ahead and clean so let's just wipe that junk off some alcohol and this and before I do that I'm going to heat it up a little just that the flux comes off easy because easyier I guess yeah that stuff comes up a lot a lot easier when it's hot so I heat the flux up with the hot air and just gets away from my chip which is very nice of it now what I'm going to do is I'm going to remove the lead that leaded solder that I just put on the on there I'm going to apply some flux I'm going to do it in a really bad way by using tweezers because I lost my syringe which I usually use for this and my this is some mtech 559 right here now the goodwick that I use actually has some flux inside of it but it's not really as good as this stuff and this is going to help me get rid of all the solder that I used to Tin it I want the pins to be flat in this case I really do want the pins to be as flat as humanly the pads not the pins losing my mind I want the pins to be flat it's going to give me less of a chance of it being a nightmare to resolder the chip okay now I'm not using the flat iron for this because having the elbow that I can on this curve tip is that actually makes life a little bit easier for me so I'm going to cut off some fresh Wick keep in mind all this work I'm doing I'm doing on a chip where I don't even know if it's good that is why smc's are such a [ __ ] waste of time I have no idea if the SMC I'm using is good this is not a chip from Mouser this is not a chip from Digi key this is a chip I pulled off a board that I bought on Alibaba with a hole in it usually I use the flat tip for any type of wicking but here I'm using this tip for the wicking instead because it it just it's easier to get into these little creases and cuz you you can't really see it from here but that this is this kind of like under fish like material that's around the pads so the pad it's not like the pads are just there and you can just easily get to it with a with flat the flat tip you really kind of have to dig in there to get this [ __ ] out and this tip does a good job of that also one of the things to realize is you're not going to get it to be perfectly flat so just [ __ ] give up on that idea you will rip every single pad on this SMC trying to get it perfectly flat don't bother I'm sure that there are people out there that just to troll me will try to figure out a way to get it perfectly flat and if you can that's great you wasted hours of your time on something that is totally inconsequential there are some chips where you need to get absolutely perfectly flat and this is not one of them this is one of those chips you just pray and you thank God the moment that you have something that's remotely close to Flat it's going over it again and you're just going to have to accept that that's the best that you're going to do so here I'm pretty much close to that point cuz you don't want to scrape or you w't want to break the first layer and destroy the traces or destroy the pads just because you were this OCD lunatic that wanted it to be perfectly flat so don't don't do that to yourself so okay we're going to get another SD safe paper towel here I got to get better way to set up this mic so it stays by my mouth all right okay and clean it's easier to sell hot flux at GTFO than cold flux so I heat it up now I'm going to try to do just inside the chip because around there is the nasty flux on the on this clamp I don't want to spread the nasty flux from the clamp around my chip while I'm trying to clean the chip we're just about there n after this we're going to go over some of the most common mistakes that people are going to make when replacing the SMC at least the ones that I mean this is this is an opinion because ultimately the the way that works is the way that works for you so this is is just my opinion but these are what I consider in my opinion to be the common mistakes that people are going to make so let just going to clean off the SMC chip itself okay nice try Okay so the first mistake people are going to make is to put the balls on they're going to put this they're going to put this little chip inside this clamp and then they're going to put the stencil on top of the of the chip because they think that the chip itself has to be secured inside of the clamp and then I'm just going to put the CL the stencil on top of the Chip and you probably can do it that way the problem is that it's going to create a gap between your stencil and and this and that Gap is going to cause all sorts of misery so once the ball drops after the ball drops it's going to be there and it's going to move around in combine with other balls or if you're using solder paste instead of solder balls you're going to make solder balls that are too big will be different sizes than the other ones it'll be a complete effing night here I might actually include a clip at the end of this of SMC reballing hell just so that you can see so you can feel better if you're one of those people who did something that uh cause it to be a complete mess so I'm going to clean the stencil and clean the chip as best as I can let's get rid of the remnants of junk around it so what I do and again you can do it differently this is personal preference if I'm doing a like a PCH or a CPU or a GPU I will happily put that chip inside of the clamp then I will press the stencil on top of the chip here [ __ ] no what I'm going to do is I'm going to attach the chip to this because there's just no room for error this is 2 or3 mm balls there is no room for this to not be absolutely positively 100% aligned anything else and you'll have balls combining to form another ball who knows if this [ __ ] up in this video you may even get to see on camera the balls combining to form other balls and all that miserable [ __ ] so first thing to do is to get myself some heat resistant tape is known as Captain tape and I'm going to tape this directly to the stencil so here we're going to get to the part that I suck at which is aligning anything to be straight this is not my strong suit all right so we're going to take the chip put the tap on the chip all right so this is the chip this is the stencil This is BS this is real [ __ ] I hate doing this so much like stuff like this is what drives me to look for jobs in networking or Security in system installation I mean this eventually you will line it up okay and once you line it up push down now we make sure that that I of course it [ __ ] moved it's always going to move as you go to push the tape down why would anything stay where it's supposed to when this is why would I be able to buy this chip with balls on it why like why make life easy when you can make life a living [ __ ] hell and get away with it because you're Apple I wouldn't make life easy for people there's a little fiber in there mofo oh and I just aligned it too let's see actually that looks like a little dead bug doesn't it that's a little fiber that's a fiber that's a fiber from my ESD save paper towel all right get rid of that is there a chance and oh hell no it's laughing at the tweezer it's like are you you kidding me you think you're going to move me through that no way okay okay you little prick yeah time's up get out of there and we put it back on let's move this microscope up so I have more room to work with my hands I think that's pretty well aligned so make tape it on there we push the tape on there then we make sure that it's still aligned cuz that [ __ ] can change any second all right now we tape it the other way around because God knows it's going to try that little piece of tape cannot be trusted cut off the excess tape and of course in making it neat it misaligned piece this is just [ __ ] okay we're going to take another piece of tape go over it because I know from experience that if you trust one piece of tape it will troll you it'll make your life hell okay put the other piece of tape over here it's aligned okay so here's what I'm talking about when I say don't use the SMC clamp so this is the kind kind of thing that have to be demonstrated on camera so this over here has uh might as well show it to you under the microscope so you see how this is cut out for the SMC over here if this is cut out to fit the SMC perfectly that's great this this here is really great when you're actually cleaning the SMC this is good this is not going to work now because I have tape over it so that I could tape it directly to the stencil since it's taped directly to the stencil it's those is not going to be the indents over there for it see cuz it's covered in tape so this is not going to work because that tape over here is has a you know it's room like it's not going to fit in the stencil properly so here's what I'm going it's not going to fit in the clamp properly make sure it's still aligned it is great all so what I do is I put this aside I'm done with this thing and now I'm going to use a regular clamp which I put over here all right and I'm going to put it in this clamp but I'm going to push it down very nice to make sure that it's not going to move around or anything and of course cuz I'm a paranoid freak I'm going to make sure it's still aligned I trust this [ __ ] as far as I can throw it which I shouldn't say that because you could probably throw this thing pretty far it's a tiny chip all right okay then I'm going to put it inside of this clamp this clam pretty much just grabs the stencil so I'm not grabbing the chip I'm not grabbing the chip I'm grabbing the stencil okay now I'm going to take some solder paste so I have a lot of different solder pastes here oh by the way this is another thing that's worth discussing so solder paste versus solder balls so you have two choices at at this Junction you can put solder paste in there and use that to create solder balls or you can just put solder balls in there if you're working with a CPU with 75 mm balls if you're working with a graphic strip that has 45 mm balls just put balls in there you put the balls in you put it in the BGA machine you bring the nozzle down and it heats the balls and the balls melt onto the chip and everything's fun that's great now here's what's going to happen when you use solder balls on here if you put solder balls in there you're going to put a solder ball in each one of these individual holes right and each one of these individual holes you're going to try to put a solder ball first thing that's going to happen is since they're so small you're going to wind up getting two balls in one hole so when you're putting when you're running around with those balls and you're putting those balls into the hle for a CPU or a graphics chip this only one ball is going to fit in the hole over here you can very easily fit two solder balls into one hole or have a situation one of the solder balls is sticking up out of the hole and then you have to go and pick out each one of the [ __ ] balls that fell into one of those holes the second thing that's going to happen is that the ball itself is going to get excited it's so excited that it's right about this to get slded onto the SMC it's so excited to be getting heated up that it's going to jump right out of the [ __ ] hole and the ball is going to jump out of the hole and then it's going to melt over here and it's going to be like half it's going to be stuck in your stencil it's not going to be soldered onto the [ __ ] pad and it's just a nightmare and a miserable mess so what we do over here is I'm going to put some solder paste in here I have a few solder paste to choose from and I'm going to spread it on there I'm going to get it into each hole so and it's not going to jump up like the the soer balls do and I also don't have to worry about putting too many balls in one hole whatever fits in the hole fits in the hole and then I scrape away at the top of it so that only enough to fit in that hole is there you don't have to worry about a ball stacking on top of another ball and sticking up out of here I can't get rid of multiple balls in a Hole by doing this but I can easily get rid of excess solder paste by doing this you may ask if if I can solder pace is so much easier why don't you use it on a graphics chip or why don't you use it on a CPU or any of those things if you're trying to put balls on one of those chips the reason I don't use it on those is because it's harder to get the balls to be the the exact every single ball to be the exact same size and since I don't have those problems in that scenario it's just easier for me to not use solder pay solder pay you have to make sure that each individual ual hole is filled up and when you have larger holes to deal with and when you have 900 balls versus 90 balls that is a huge [ __ ] pain in the ass so pretty much with the different sizes you're trading different types of pain in the ass and what I find is with the smaller chipsets that I would rather have this uh this pain in the ass than the other type of pain in the ass so I have two different solder pce here I have amtech let's see this is yeah amtech 1379 one that's a good Let It solder paste and then I also have this stuff over here this is ker EP 256 solder paste I don't even remember buying these things but I have them here in my drawer and one of the things about solder paste if you don't store it properly if you don't refrigerate it or keep it at whatever temperature it's opposed to you get I would say a month two months before it's [ __ ] up so if you notice that trying to do this job and you're doing everything I'm doing and the solder paste is doing all sorts of things that you're not telling it to uh then there's a good chance that your solder paste is [ __ ] up and I also saw this damn thing misaligned so let me just fix that before I start better I'm losing it okay put the chip into the clamp and hopefully this thing works get it nice in there in the clamp okay I take the solder paste I want to inject this into every hole I know laugh balls in every hole and you can't see this s of the microscope which sucks but is what it see I don't have space to do this the way I want so I'm going to try to inject inject the solder paste in every set of holes so I'm pushing down on the chip kind of hard and then I'm pushing down on the the syringe hammer hard because I I don't want to have the solder past hover above the hole and not fill it I want the solder past to fully fill each one of those holes and this stuff is cheap you like 15 20 bucks gets you a whole syringe and this is not even buying in quantity so feel free to use more you're going to wipe the excess off later and again you want to fill every single hole that's that as soon as you're done with this [ __ ] don't leave it open put it back in it syringe I mean it's it's container so you put the cat back on there again good work habits good work habits are going to keep your life from becoming a cluster [ __ ] and the biggest enemy of good electronics repair is when your life and your desk and your table and your mind are a cluster [ __ ] cuz when this stuff starts to not work it'll drive you nuts because you'll be trying to do a job and it won't work because your tools are not working and then your tools are not working so you can't get it done so you get driven more nuts and it's just a terrible terrible spiral to hell so I'm going to clean off my tweezer real quick here all righty some alcohol get rid of the excess alcohol in the end okay and I'm going to wipe the paste into every single hole don't touch this stuff this is filled with lead keep in mind what the purpose of solder paste is the entire purpose of solder paste is this stuff is made to flow freely to the bottom of every single one of those holes it's meant to seep into little places and get stuck in there that that that is its [ __ ] design that is its intended purpose so what do you think this does to the pores your skin and did I mention that it's made of lead so yeah don't don't don't touch this [ __ ] don't touch this stuff I like having nice skin I like not having lead in my bloodstream or inside of my skin or anything like that okay so then we're going to we're going to wipe off the excess this is important because again you make the ball too big you won't be it'll stick up through the stencil you won't be able to get the SMC out of the stencil you will rip the pads off of the SMC and the SMC will be [ __ ] and that's no good so take your time and getting rid of any bit of excess I wipe away and I wipe away until I can make two or three wipes and my paper towel is still white and I have any bit of gray get rid of that excess [ __ ] a bigger ball is much worse than a smaller ball it's best to have no error at all but if you are to have an error a ball that is too small it's much better than ball that it's too big keep in mind all these balls are going to be dropping anyway so now I'm going to put my hacko f801 with the 4 mm nozzle to about a heat of six I'm going to turn the air all the way down to like 9 or 10 and the reason for that is that I don't want the balls to jump out I don't so I'm going to heat them slowly the balls are going to get heated nice and slowly the whole idea here is if I run in and jump in on there immediately that what's going to happen is those it it's going to get excited and that solder paste is going to explode out through the stencil and you'll see that every single one of those BL there's two things that can happen either the solder paste just slowly kind of turns like a sphere just turning or and and it just rolls over and sits down like a nice little solder ball or it jumps up excited and turns into a ball that combines and with other balls and we're trying to avoid the second one from happening so I'm going to preheat it first because I don't want to get to get a HT too fast I don't want to excite the stupid solder paste I'm telling you it's going to look easy when I do it now but you'll see when the [ __ ] balls jump out and combine and form other balls it's the most frustrating [ __ ] in the world so take your [ __ ] time see one of them is trying it right now you see that [ __ ] is trying to jump out and turn into another [ __ ] ball on the right we're going to give it a chance to correct itself and then there's another one that oh okay so you can see what I'm talking about right like that ball over here okay let's see how this came out so can I remove this or is it a mess all right so I I [ __ ] it up a little bit you're going to see how I fix the [ __ ] up a little bit that is a joke all right so that didn't go the way I wanted it to at all try again that was awful so some of the balls were too big the result wouldn't allow it to leave the stencil so we try again uh where's my other clamp other clamp is over here one Saving Grace here being that this is leaded solder paste is I don't have to run over it and Tin every pad again e for for tried to scare me into thinking that you're a broken pad freaking SMC I hate smc's man h clean the chip you may wonder why I don't use flux on there putting flux under there is a great way to get it all to get the balls to start jumping out of the holes because the flux is going to kind of bubble a little when it gets hot okay and now we still have all those balls and the stencil hot air at Max Air is going to get rid of that very quickly me clean the stencil off with some alcohol okay now let's try that entire process again and like it's probably not smart for my business or my image to upload videos of SMC reballs that go [ __ ] up but the thing is I really feel like what you're going to learn from is not just what to do but also what not to do and I feel like a big confidence Builder is when you see that somebody you who's done it a million times who knows what they're doing also encounters the same mistakes as you there's nothing that's really more discouraging than watching somebody do this job that is just so absolutely perfect without flaws and then you doing it yourself and it going the exact opposite like I feel what's going to help you is you seeing um all this stuff mess up and then realizing oh it happens to everybody which is why I I really I strongly believe in not editing the screw-ups out of these videos so because it would be really easy to just edit fuckups out of them and you know make myself look like a genius that doesn't that just never made a mistake in his life but how boring would that be kind of inspiration would that be to you you know would just make me want to give up all right let's try this [ __ ] again okay I'm going to go like this this is a royal pain in the ass yeah aligning things is not much my strong suit I could never put a clock on the wall straight or hang a painting straight or like after a while of doing this you just start to want to pass out okay now stay so a little bit of moving of my finger that I did to actually get the thing taped on properly was just enough to totally misalign the [ __ ] ship like where is the science in this where is the analytical thinking where is the fun in this [ __ ] cruel this this is this is be this is [ __ ] this is really [ __ ] this is not fun this is just horeshit [ __ ] Apple for forcing people to do this seriously [ __ ] Apple in the ass for forcing me to do this because you don't want to make programming of this available because you don't want to sell these things to people this is this there's no [ __ ] need for this other than just just just spite that's what it is it's just spite like [ __ ] you people who want to repair our products like you can all eat it we don't give a flying [ __ ] about you we're going to make this [ __ ] as miserable as humanly possible we're going to laugh at you when you try to fix it it's [ __ ] all right so let's let's get this thing going is it aligned it's aligned let's go all right get the big clamp going to get the big clamp I left the big clamp right in front of me and I didn't see it because I'm losing my mind okay I'm going to get the stencil into the big clam make sure it's nice and secure in there get my solder paste and we're going to try this [ __ ] again all right for for e this point I'm satisfied that there is solder paste in every hole now to get rid of any excess getting rid of the excess is very important if you don't get rid of the excess what happened 20 minutes ago will just happen again one of the things that may actually help with getting rid of the excess is tighten the clamp a little bit that push down on the middle of it and then wipe around the chip this is actually something that I usually do that for some reason I forgot to do last time cuz this stencil this this [ __ ] is not flat like you you can get you think it's flat but just look at it even if you B just bought it and you think it's flat when you get it it it's it's not so you push it down a little bit onto the chip and then the EXs will pop out if you have any EXs on there so this is a good way to get rid of the XS which I really don't understand why I forgot 10 minutes ago they're just going to turn this thing around right now it's nice song off of Van Halen's live album see when it's pushed down flat there's going to be less space between the stencil and the chip which means less space for solder paste which means less solder paste in each one of these so just get okay now let's hope that that goes better so I'm going to have the heat on this thing turned up to about 6 and a half and again I don't want these balls to jump so I'm going to put the the air down to six now which is almost no air at all going to preheat it and take my nice sweet time with it because again the more time you spend preheating the less chance of balls jumping and combining and turning into other balls I'm going to preheat from further away I'm going to give myself a good minute with the preheating for yeah started to melt a little bit I didn't give it a full minute of preheating where the hell I'll go with it the left side is scaring me do you see where the left side is scaring me I have no idea what happened happened there I'm afraid to find out but what are you going to do let's take this thing off and see what happened get rid of the tape for that looks like a mess that looks like a total mess yeah [ __ ] that I don't know what that is but that is not usable so we go for try number three what happens if I put the you know how I always say that when I try to do things in a video how it never works out the way it does in real life what happens if I actually just put the stencil over the over the clamp over here just for the hell of it because it never works in real life maybe it'll work in a video cuz a lot of the things that work in real life don't work in a video so I'm kind of curious if that rule works the other way around like will something that works that doesn't work in real life work just because I'm doing trying to record it it would be hard for this to go any worse than it already is so let's just try it this way that pin that still got some BL get out of there oh boy it's about time to get home and go to sleep I don't know why I always put the videos at the end of the day I was thinking about changing this and actually putting the videos at the beginning of the day because by the end of the day I'm just I don't want to I don't know I just kind of lack the inclination to fix anything and so I'm kind of recording me when I don't actually want to be working which is not exactly the best plan for creating inspired video content okay so let's see if this actually winds up working out differently so let's see just how much God wants me to be wrong on camera let's see I'm an agnostic person but I do believe that there is some sort of God that likes to make me look like an idiot on YouTube let's give this another try for stupid cable H my cable is Tangled around the chair and I'm sitting on it okay now I do the push down all that excess can GTFO turn the [Music] clamp push turn the clamp push turn the clamp push all right is the hot air station ready to melt solder sure is wouldn't nice try wouldn't that be great how did I miss that it is time to go home and go to sleep yep okay ready to go got the air at 9 and A2 and the Heat at 6 and A2 I'm avoiding all my usual precautions because that's face it none of them actually have worked anyway goodbye fiber you piece of [ __ ] you [ __ ] all right we're going to get that one later and there's another ball there that needs to GTFO you see the one I'm talking about this one over here this ball can suck it okay now the ones that are a little messed up I kind of want to get them to form into a proper ball so I'm going to try to do that by getting some flux on there this is way too much but I don't have my syringe with me so oh well one of those balls I'm going to out to place manually the one that popped out okay H there's really no way around touching the tape that's filled with fluxes there oh okay just making sure let's see what we have now I'm going to take this below a solder melting temperature at around three and a half see if I can get this off all right let's see what this looks like is that going to look good or a complete mess for keep in mind this entire process of being undertaken on a chip that came off of a dead motherboard I did one earlier today that wasn't on camera that went pretty well like better than this at least something about turning the camera on that makes all the repairs go to [ __ ] okay this actually has hope all I got to do is put that one ball on there and I'm good so this is where having the little portable solder balls is cool so I don't like pouring these solder balls in there who I just sprayed a bunch on the floor whoa whoa whoa whoa whoa whoa whoa whoa whoa okay all right that's going to be a nightmare to clean up my floor is now filled with lead all right I'm going to pick one single ball out of here I place that single ball [ __ ] who am I kidding that ran away into the sixth Dimension very quickly and take that one single ball put it right here who am I kidding again gravity this is the other thing that sucks about using individual balls gravity is no longer gravity when you're dealing with [ __ ] that's this tiny like okay drop because there's gravity no no good no there is no [ __ ] gravity so what works is putting the only way you're going to do this is by getting some flux in there because then the ball is going to stick into the flux see how that works and I also might as well put some flux on there so that all the balls that are not really nice looking can get reshaped while the hot air is on them that's way too much flux but who cares the time to care about such things ended about an hour ago okay so we put the heat on the iron to about 6 and a half air flow to about nine wait for it to heat up might as well just preheat in the meantime so I got too much flux on there anyway nice try you wanted to go over there and become another ball didn't you no [ __ ] you nice try little ball melt melt [ __ ] you you already attached oh you [ __ ] you combined and turned into another ball okay now I got two to put in there that's great that's great that's hilarious okay all right let's grab two now I'm going to do this one at a time one ball okay we're going to melt that one ball on there zoom in on that mofo Target haha you've dropped now we got to do the other one one before I do that let's wash that huge Gunk of [ __ ] I just got off my hands okay let's grab the next ball the next individual solder ball okay and heat that little thing up drop don't make a run for it you made a run for it you little [ __ ] drop let's zoom out so that I can see where my iron is and awesome it's on there okay now I'm just going to run over the rest of the balls the air up a little higher are you whistling because you like my balls okay listen this ain't getting any better so here goes nothing waa this paper towel is way worse than the last set that I had yeah okay we go again this really is for me about as good as it's going to get this is not getting any better vineer you were on camera I can try and remember to delete you but since I edit these videos at 1: in the morning I'll probably forget I'm going to just brush my chip off in the Ultrasonic Cleaner really quickly and we'll get the slding it onto the board [Music] ultrasonic is sizzling toothbrush some of the junk okay run it through the alcohol and onto a paper towel it's my chip right here my beautiful chip okay motherboard needing an SMC what else could possibly be wrong with this board what what else could possibly need to be done to this motherb oh my God this is a cluster [ __ ] this is just this is yeah yeah this is some [ __ ] okay sometimes I take on things just kind of as a challenge like this one guy sent boards that his text [ __ ] to [ __ ] and they actually required wires being run underneath the SMC see I'll notice there's one pad that's ripped it's a ground pad not something to be all up in arms about because it's just a ground pad there are many other ground pads so we're going to we're going to do our best to align this damn thing and all right so let's get some flux on it here it really does matter if you put too much CU then the chip will bubble and bounce around more than it's supposed to so after I put my flux mess on there I'm going to wipe the excess off I really need to get a clean room wipe for this that's the thing these paper towels used to actually be good they used to not leave fibers I either cheaped out and I bought a different one or something what the [ __ ] mean I can't really see much under the chip which is the important part like what you see it's wow I guess this may be surprising but the consistency in fibers and Sheet paper towels is not what you would think anyway there's no fibers under the SMC which is really all I care about okay now to check another one of these that I did because I actually forgot the orientation so the other 3115 SMC that I did ear was which yep facing to the right so let's take the chip here it goes nothing H that flux is really reflective by the way Apple thank you for marking the board so I know where to put the chip thanks a lot guys I really appreciate that you put those little little uh L-shaped brackets on every corner so I know exactly where to put it so that I know that I'm aligning it the way it was originally thanks a lot Apple Engineers for putting that little effort in to make my life easier you know what I could do I could actually look at a board that has the chip soldered on see where's it where's one that I haven't [ __ ] with 3115 with the here we go and let's see what the distance is so we can get an idea of the alignment there's that much space from each resistor on this one and so right at those two holes so those two two holes on the left side it's going over those two holes and the top side it's like right at the edge of those two holes let's see where I am over here why am I still holding this my nuts try that again okay on the top side it goes right to the two holes and on the left side it goes over the hole push down so that it's situated on the pads pray the BGA God time for soldering this is where you really just pray this is a you chip so this will take a while also there's a lot of flux there so more fum extraction pretend it's a really big LED driver heat away all the excess flux oh it just moved in a place you saw that it just moved into place that's beautiful but it's a big chip and I and there's Center balls that may not be melted yet which is why I heat it more so I can see it move back and forth move for me SMC that's right move back and forth for me so you've been moving back and forth for about 10 seconds now which means that I'm done I'm heading out of there with the Heat and the SMC is on the board I don't I don't really want to mess with it and make but the balls are really small and there's not a lot of them so I'm going to say after about 10 15 seconds it's dry just to cool it off a little bit right let's see what that looks like under the microscope [ __ ] you air filter [ __ ] you hacko turn off there's a damn near microscopic chance that this [ __ ] actually works come out microscope okay let's look at you under here this may actually work I mean I don't know I mean the SMC soldering job I mean not the board the board is a you saw what the board looked like this board is no has very little hope of ever working again this is one of those boards where I just kind of took it on as a just a challenge project because I don't know why like in in normal my by my normal rule I would have tossed this [ __ ] in the garbage a long time ago so let's see what happens before I had no green light on the charger and now what do I get do I get anything holy [ __ ] I got a green light in the charger pretty cool so I didn't have a green light in the charger before now I'm going to get greedy now I'm going to do something that I probably shouldn't do at the end of the day after being here all day I'm going to push my luck a little bit and I'm going to see if the fan spins and of this is God's way of saying don't do this so the fan wire actually broke oh man let's let's grab a fan where's a fan quick my test fan wire die here we go here's a fan for one of the machines I need to refurbish for the window again I'm getting a little crazy here I shouldn't expect much out of this piece of [ __ ] but do I have the fan spinning holy crap what [ __ ] yeah okay the spins now am I going to test the rest of this right now no I'm going home let me explain look at this let me just show you let me show you how much work there is left on this little challenge pile of [ __ ] so again just to give you a recap this board originally did this we had we had this going on we got this going on this going on and like look at the backlight section of this like look at the fuse not only is there no fuse I didn't remove that by the way there's no pads and there's no fuse not just the fuse is blown but this thing is just [ __ ] man I'm kind of tempted to continue I really should go home like if I had half a [ __ ] brain I would go home's let's just get let's see what we can do let's see all right so the LED driver oh my God okay that needs replacing this Board needs to just go in the in the trash all right but [ __ ] it just since I spent so much time on it already yeah look at that nice LED driver oh oh disgusting [ __ ] disgusting all right get up there okay so we're going to have some work to do here first let's see if the pad is gone the pad may not be gone that's the thing you got to think about the pad may not be gone it may just be covered under oxidation and [ __ ] but it may not be gone I only have 62 GB free so I actually probably should cut the video because I'm almost out of space but I'm not good at this N I can delete a video from yesterday that's 71 gigs that'll give me some space to keep going let's do that empty bin and now I got 128 gigs I I don't know if 128 gigs is going to be enough for a board that looks this bad but let's see first thing to do is that are those just is there oh there's a one pad oh boy and the other one waa there's like a kind of a crescent moon shaped [ __ ] stain of a pad let's keep going yeah so the reason I changed the SMC on this is because all conditions were present for have a green light but I had no green light okay we'll go back to the backlight fuse later let's just get that led driver lifted man I really should go home I don't know what the [ __ ] I'm doing working on this boort yuck I'm not going to Wick the pads like you should with an LED driver replacement because I'm fairly certain that they're being held on the board by [ __ ] I'm making an executive decision there to not rep to not do anything on those pads okay let's get an LED driver on there let's remember the orientation I hope that's the orientation I feel like I may have forgotten the orientation oh God I'm turning into Sunny Okay Melt you [ __ ] I had it sitting too high see I didn't push it down which is wrong but I got the chip to dance which means it's on there now for backlight fuse is I hope that feedback V isn't destroyed oh you're good feedback V is good okay now what am I going to do about this [ __ ] like supposed to S to refuse to this really that's [ __ ] oh what's another wire on a board that probably has six or seven of them already all right we're going to put a fuse there I'm going to see where else I can grab that point and or just run on a wire no big deal wouldn't it be funny if that little [ __ ] stain of a pad was actually enough to carry backlight I mean that's obvious that's it's a very wishful thinking but it would be funny wouldn't it I I can't help myself the curiosity is killing me I need to know also this the flux on this tweezer is by is complete garbage at this point let's just what clean that off okay okay I got to know I mean I got to run a wire anyway because that's I'm not putting this board back into the world being held together by [ __ ] but I still still want to know okay so what do I need so firstly reballing is done and when you're done with the tool put it back put it away you even if you don't put it where necessarily supposed to be just get it out of being right in front of you not drinking that anymore solder balls over there thermal paste over here this there over here my fan first let's see if there's a short to ground on backlight output like needless to say on this this board that looks like this that's really something to check see how much space I have left on the on the recording Drive 104 gigs all right so I'm I'm good okay let's so for backlight output dude I'm reading what I'm supposed to okay not exactly what I'm supposed to but much closer than what I thought I would get all right I got a ram stick all that's necessary now is a screen and let's see if I get a picture I mean do what you there's no chance do I actually have CPU V core on a board that looks like this I haven't checked the CPU Vore area oh those those resistors are oh am I kidding let's see am I going to get CPU V core on a board that looks like this cuz if that's what happened to PP bus G3 hot at the backlight area what happened to PP bus G3 hot at the CPU vcore area by the CPU IM imvp ton resistors that's going to be destroyed all right any but let's see one step at a time fan spins do I get anything now I'm just kind of being Icarus trying to fly too close to the sun screen doesn't even activate which means no CPU VC core most likely okay can't have everything let's see let's open this get shut up air filter go back to low all right okay let's open the board view for this board and continue man wouldn't this be cool if I can actually get this piece of [ __ ] to work CU you saw what this thing looked like this looks like [ __ ] and balls this really needs to be given up on all right so U 7400 U 7400 so R 7403 r742 where are you you're over here okay what do you guys measure so these need to be present and working for the CPU Buck regulator controller to know the switching frequency to get from whatever the source voltage is to whatever voltage it wants to make the CPU V core be the problem is if it doesn't know what that is then you get nothing and those resistors are totally fine H let's see if I have P CPU vcore ppv core undor soore CPU where do I find that I find this over here okay let's measure turn the thing on again let's see if I have that maybe I'm just really tired and I'm mistaking no backlight for no image okay fan spins voltage on CPU V core is 1.1 okay let's see what this image look does the screen activate not at all H let's see what the LCD connector area looks like the LCD connector area actually kind of looks fine so CPU V core comes on HM let's check the new u9000 area let's see if it's telling the LCD to come on that'll tell me if it detects the LCD so which one of these is U 9,000 not you not you you not even close are you U 9000 no you're U 9000 all right so I'm pin one over here LCD IG power enable so when I plug the LCD in let's see if I get anything on there does the computer even know that a screen is connected I should actually plug in a speaker I mean for all I know this board is beeping at me that it can't see the Ram or the ram is bad or there's no Ram slot that works so let's find a speaker this is a speaker here you want to hear a dong you want to hear a nice long dong everybody wants to have a nice long dong oh it's beeping see I'm being a [ __ ] idiot this is what speaker is for okay grab this Ram stick from the machine I needs to refurbish for the window and plug you in are you still still going to beep at me still beeps maybe it's a bad Ram slot let's try the bottom Ram slot let's face it one bad Ram slot in a board that looks like this is expected and this board has what is most likely a dead CPU or a dead PCH which means it can rest in peace which means that this entire effort was kind of a waste of time but the point is at the very least you get to see that the SMC replacement worked because before not only did you not get a green light you also didn't actually have the board turning on now it turns on it has a green light There's No Quarter fan spin but it's it's just a [ __ ] piece of [ __ ] and I you no I'm not replacing the CPU on this board I'm not going to replace the PCH I'm not I'm not I'm not doing any of that this board has had its time and it is done but at the very least I got to go through the entire process with you and again why do I not like SMC Replacements cuz all the boards that I get where I know in my heart that what I have to do is replace the SMC all the boards that I get that need an SMC they're cluster [ __ ] like this like you know again you can see that even if you're really good at this even if you are 10 times better than me and your first SMC reball works you have to find it off a board that doesn't work you have to take that SMC and you know you have to prepare it and then you have to solder it on which is kind of a pain in the ass and all of this is being done on a board where you don't know if it's going to work after and you're taking that SMC from a board that you don't know if it worked to begin with so this is why I hate replacing the SMC on a MacBook motherboard this is why I I don't I I put those repairs usually closer to the bottom of the pile and hopefully you learn something hopefully you learn from all the silly nonsense asinine [ __ ] mistakes that I made made and I'm honestly I'm kind of glad that every single kind of mistake happened in one video so you had the mistake of balls combining to become a bigger ball you had the mistake of balls jumping out you had the mistake of misalignment I mean you had literally almost every single mistake that you could make when reballing an SMC to put it back on here every single type of mistake that you can imagine happen in this video so one of the things I say about learning you're not only learning how to do something you're also learning how not to do do something so if these videos help teach you how not to do certain things or how not to make these mistakes I'm actually happy this board is going back to the person who sent it to me and it and again this this is this is the thing about border people go like why is it so much money why is it that you know why is it $325 to fix my $2,500 laptop uh the thing is again no fix no fee like how much time do you think went into this whole thing cuz I'm not even just talking SMC let's talk about you know all all all of this stuff going on over here like how much how much time do you think all this [ __ ] took like really to get this thing to the point where it would actually function you know this took time all of this takes time and that is time that I can't get back and that is also time that under my current billing model that I cannot charge for so since I can't charge for any of this what I am going to do is I'm going to charge a rate for the stuff that I can do and you can think that it's mean you can think that it's I'm being an [ __ ] but it's a market price I mean you know again there there are there are no shortage absolutely no shortage of Mac laptop repair places in Manhattan that that that you can go to and 99% of them don't do this they tell you I'm sorry we we this board is 375 on eBay we want a 100 bucks to put it in your laptop after tax you pay five 550 bucks 325 I feel is completely totally fair and it and it really does cover moments like this where I spent over an hour on a board that at least me two hours on a board that I can Bill 0 for so that is the no fix no fee model and it works for me so I'm I'm just out of sheer curiosity I want to see if I get an orange light because if this actually sees the battery and can charge it then that would just be a miracle I know a complete waste of time because it has a dead CPU but wow see what the orange means it means that not only does it see the battery but it can [ __ ] charge the battery and you know why I'm interested in that if you know what those wires do down there if you know what all those wires do then you know why I'm interested in seeing that it charges the battery this board is a [ __ ] Masterpiece I almost kind of I I don't I almost want to replace the CPU on it and the P or the PCH or whatever is causing that ridiculous [ __ ] but no time to [ __ ] go home good night
