Make Your Own Soldering Flux, Liquid Flux

hello so we are back monday morning yeah and this time we'll speak about the flux you know many people ask about the flux and uh yeah yeah let's let's do some work let's speak about the flux i mean above the soldering yeah because obviously you use the flux for soldering see what i'm using is this thing yeah this is roasting so if you check on um if you check on ebay yeah let me see if i can switch i can't switch you know the last windows update it's it's it's it's sick you know it's so many bucks so many things i can't use even the my capture card the blackmagic one okay let's go on ebay yeah just to show you the price of the rock scene yeah soldering roasting slowly restaurants in flux yeah look how much easy look look how much is this thing like one pound and something but you can find cheaper you know you can find cheap like you can buy like one kilo with few pounds yeah and you can find a different very variation of you know but yeah and also it's called call phony yeah so can be like that or you can find it like crossing now yeah now you have to trust me yeah i come from like 30 years no really like 28 years of experience here this is the best one now you can't find different one yeah just forget just don't do research just trust me yeah it's nothing better for uh like soldering on on the boards or on um mainly with the solder iron it's nothing better yeah let's find a board and i try to do some stuttering without flux here let's just get a random board yeah okay that's a random one yeah let's try to solder something let's try to solder something yeah let me see how i can switch on the microscope yeah like that okay that's great that's fantastic hopefully the sound is good so we have a motherboard yeah like that we have a thing yeah let's say we need to solder something here let's bring it on focus it is a focus here using the solar iron yeah that's the solar iron and using the solder wire yeah that's the solar wire a lot of solder there yeah so we'll try to solder something without flux yeah without using flux okay so let's try let's try let's do it let's do it you know the solder is not even going on the pad you can see so how can i do it look it's not even going on the pad and that's copper that's a copper pad yeah how can oh okay my solder sorry it just fell off how how can i solder this thing so that's that's the soldering without flux you know you can't do soldering without flux here okay yeah look that's that's that's copper and the solder and i can't solder the thing you understand let's use some flux here let's add some flux that's the flux and i just add some flux look at the solder look at the solder look how nice is now you understand it's nothing better than this trust me i just stopped searching stop using like different paces of or whatever you use just stop just use this one this is the best one yeah look at the solder round nice yeah more flux more flux now you understand yeah that's the flux now let me explain about this flux yeah sorry what i did okay i will change a lot of things here but i can't do nothing it's it's it's nothing working on my computer so i need a little bit of time but i want to make this video because many people even on the last video we will ask what about your flux yeah that's my flux yeah that's what i'm using few things about this flux yeah how the flux works when i saw it like this yeah because it's solid it's a very good isolator yeah so if you if you try to do something yeah this is very good this is fantastic yeah the second thing yeah the smell it's unique yeah you know how it is listen to me it's like um smelling like petrol you know petrol smell some people love that smell i love that smell you know same like this you know i love this and i can't believe people use like fumes extractor just to take out the smoke this is fantastic you know the smoke of this you know i love to feel the smoke of of of the flux you know of the raw scene it's absolutely unbelievable you know it's it's a special you know you know what i mean okay now the second thing always amusing with the solar and this year so that's not question about this uh i have for fonts especially the small things yeah the small things the small things i'm using the other flux i don't know some how many flux here let me find one to show you i'll explain why i will explain why i will explain why one second one second [Music] anti-flux yeah proper expensive these things is like 25 pounds from my point it's you don't want to know my point yeah but it's good you know why because he's um has no color and it's it's it's it's great because you can see let's make a difference about this and the other one yeah yeah so this is the the the the minus on this flux here is nice if you're using once but get burned and when he get burned he changes his color yeah let's try to use it let's see what happened yeah i try to use it let's say we have to solder some things yeah like this the board yeah let's use the flux no i'm bored i should take a phone you know because even on these kind of motherboards i'm using my flux but let's say in small things let's find some small things like this yeah let's put flux there but even here here is fine yeah i'm speaking more about the phones here you can see if you do some soldering things yeah it's still fine it's still nice yeah you can still i should take a board for a phone board yeah you can do some soldering here solder some things but after a while yeah you'll see the flux to change his colors and the color will go like brown still nice still can be burned yeah it's no problem but you can see the color is changing the color he's changing the color yeah i can i can't see one second okay so it's not it's still okay still can be used yeah but it will change the color when it is getting burnt the other one don't take one yeah but don't get confused i'm not using this on the laptop motherboards i'm using on the phones here this this is nice look it's clear it's clear yeah but the downside of this one look at the smoke yeah it's getting evaporated evaporated very quickly this is clear it's nice the other one is a little bit dark you can't really use it on phones let's try hot air make a difference hotel uh with hot air with hot air actually i'm using the amtec one what how can how can i explain how the flux works here so actually the flux one second it's very good easily isolator yeah we spoke about that when it's hard when it's liquid when you mulder the flux this flux get like an acid and it's cleaning everything that's how the flux works here always i'm using on the soldering with the solder iron by 99 i'm using this flux here when i'm working on phone i'm using the other one but always yeah i think anyone knows about this but the the big problem is the liquid flux here many people ask about the liquid flux and my favorite flux is this one and we will do some flux yeah let's do let's do some flux liquid flux this you can turn it out on a liquid flux and it's fantastic it's great and it will make the difference after that yeah one second we have here another thing with flux i can open now there's no way to open this so the thing is cheap thus i like this thing it's cheap if it's cheap anyone can afford it okay so what i will do this is new yeah i will take some some bits of uh frosting yeah californium here let's take more yeah that's how you can do your liquid flux here like this okay and now i'll take some alcohol he's a prophylic alcohol this is cheap also you can find it probably many places yeah okay and i will add some alcohol there now it will take a while so if you lay like from one day to the second day will be everything will be dissolved yeah and you'll have liquid flux on our case because i don't have one day we are recording now i will accelerate the process yeah i will accelerate the process but don't do it because you know this alcohol actually it's burning like a yeah so i will just hit the the thin just to dissolve the russian better quickly sorry yeah don't worry you can do a fire you know just leave it just wait one day here just wait one day just want to accelerate the dissolving process so we can do some liquid flux here yeah but don't do it just wait like one day and it's fine you know and you'll have these flux long time you know even now i have my flags which i made it like two years ago yeah it's here this i made it like two years ago and i still have four years okay still a little bit there okay yeah i think we have liquid flux now how much alcohol and how much these things serotonin you can put just test and see if it's too liquid put more rust in here okay it's not hard it's easy okay so we have liquid flux here we have liquid flux let's leave it like that yeah let's try to find let me try to find something better above foam board here yeah phone board why not yeah okay it's not completely dissolved it's still a little bit there it does happen what you when you try to do the thanks quick yeah but take your time you know it's no rush just leave it like overnight and the second day you'll find this everything is dissolved and keep this covered here if you store the the liquid in something just keep it covered because the alcohol will get evaporated over the time yeah it looks fine it looks looks yeah it looks yeah looks fine let's try let's try to do some more with this flux okay uh let me switch okay let's say we have a chip here and we are trying to desolder the chip take out the chip yeah let's try to let's try to do it with this flux here i'll take with the with the tweezer little bit [Music] let's try to do now that's a nice look look how it's bubbling you know i love these things and i'm gonna explain you why yeah and the flux is still there you can see so you can see the flux is still here yeah let me let me explain why i love this flux this liquid flux because the burning temperature is very high compared with the other flux yeah with arm tech one which is getting evaporated quickly this one is not doing this yeah so actually even if i do something i still have the flags there let's do a test on a laptop motherboard yeah let's compare so let's say we have uh two chips this chip and the other ship yeah okay here let's use this flux yeah i can't see normally i'm using this thing for flux you know i'm i'm smoking electronic cigarettes and i have this kind of bottles yeah you can see it and i can yeah you can see so i can drop like only tears of flux yeah so that's what we have to do okay let's try the other flux is just evaporating it will get evaporate i'll show you yeah but this one look how it's bubbling and i am on 500 degrees i'm on 500 he's not even supposed to work here with 500 degrees you understand when you desolder a resolder chips 500 is too much okay now let's use the other one on this side here yeah let's use the amtec one to understand the difference cool actually this flux is quite good let's use less let's try to use the other one here where is the other one one second let me let me check with the other one one second one second i think the other one is gone maybe it's fake you know these days you don't know if you buy the original fences or not um i wanna see my flux yeah this one this is supposed to be same flux or maybe it's fake yeah but let's try it this is supposed to be same flux i know i have one more one second even one second let me find that flux which i was very disappointed about the flux maybe someone took it from here one second [Music] oh yeah it's here yeah let's try and use this one let's try and use this one let's find another chip one second like this that's using the mosfet yeah uh that's good that's what why i don't like these flux because if i try to do something the flux get evaporated very quickly yeah like here you can see nothing there the flux just goes away just get evaporated because i can see the smoke you can't see the smoke it's a lot a lot of smoke and compare the other one yeah with the liquid flux if i try to get down the mosfet yeah let's say this one this is my liquid flux here with rosin okay hopefully it's on focus uh okay so you understand look look when when i took out the mosfets look how many how much flux do we have do i have here you can see so the boiling temperature is higher that's what i love this flux but the problem is you can see the color so if you know what you are doing this flux is great but if you were like with sensible things like uh let's say fonts and actually you don't know for what you are looking for we just keep working i'm using the other one the arm tank one yeah even on fonts i'm using this one if i do things which i know like uh let's say uh touch ic charging i see yeah i'm using my flux the liquid flux yeah the other thing is what i love this flux i will show you why let's go back let's go back on the motherboard here where i use the flux yeah so we took the chip out from here and we dumped on text flux from here yeah this is the amtec one so check here i don't know this is some kind of thing yeah it's it's it's it's it's just this guts disgusting and sticky and i hate these things so actually you have to clean the thing the board on my one yeah here using my one look here you can see everything is like how it was original nothing sticky you can leave it like that it's great it's fantastic on the water damage drops here because the flux go under the chips and it's insulating the pins yeah you understand this is fantastic especially on the water damage jobs this flux just because it's going under the chips and it's boiling there and after get dry is it's hard like this it's like glass yeah that's why i love to work with these flux okay now you have to understand what we compare here we compare like this this was expensive we compared like 25 pounds flux like this with one pound flux yeah my liquid flux or yeah so don't think if it's expensive is good yeah because it's not this is great this and the liquid made by this yeah use it okay and you have to trust me now and with the with the solder i don't know i can't use the object flux no it's getting evaporating it actually is not soldering you can try yourself okay so that's the thing about the flux just buy this thing cheap by like you don't need so much just buy a half of kilo maybe it's too much we like 200 grams yeah and if you have to use it soldering and also you can make the liquid flux which is great yeah and i'm using this thing when i'm using this thing this is from my uh you can find this bottle probably you can find them on ebay and actually you can use exactly how much you want okay so does the flux what you want to use it yeah that's what you want that's what you are looking for and you can't find it that's the way how you can do it and to do your liquid flux is so easy so easy i told you i made that thing like two years ago and i still have and i still have i just fill up the thing when it's empty okay yeah yeah so that's all about the flux and i show you why you have to use the flux you can't solder without the flux okay thank you for watching i can subscribe if you like the video and see you probably later yeah bye
