Ray-Ban Meta Smart Glasses Teardown

today we are doing a tear down of the meta Rayban smart glasses we're going to analyze the manufacturing processes used to create them put the glasses through a series of quality tests and give them our dfm score out of 10 let's get straight to it here is the blue jeans wayer model stick around to the end to hear about our giveaway but today we're going to be taking apart the black headliner model you can see the split lines have been created in the assembly process it's very hard to avoid these entirely but Rayban have done a pretty good job at keeping them at zero Gap first we will take out both arms which are fixed in with two screws very similar to what you would see with your own reading glasses or sunglasses so let's pop those out and let's see if we can try to get inside each of the arms and understand what technology is inside the two halves of each arm have been glued together in a onetime assembly process and and I'm going to try to cut across them using a small blade so we can access the electronics inside I'm really trying not to damage the electronics hopefully we can get a nice clean cut on the top and the bottom side just using the spudger to lever it apart and a little persuasion with the standing knife trying very carefully not to cut my finger off at the same time these arms are well stuck together and they've certainly done a good job in their design the glue they've used is very strong wrong the other way to do this would be to use ultrasonic Welding which would have made it easier to open but this process would not be a strong as glue eventually I'm able to pull the arm apart revealing the electronics and it looks like we've got the switch we've got the main board PCB the speaker module and something else that's connected to the speaker it looks as though it could be to support the spatial audio then on the other side of the plastic we have some electric grounding and what looks like EMC shielding and this is the power switch on the outside of the frame we've got the approval markings done by tampo printing we also have a metal CNC part that looks like it channels the flex PCB from the arm to the frame connecting the camera the switch has its own Flex PCB and connector and that connects to the main board PCB via a zif connector and on the main board there are also Pogo pins these pins are connecting the camera module to the main board there are some small Pham pads on the shielding can that ensure they do not come off when dropped there's a dedicated cavity in the arm for the speaker module and there's also a speaker membrane that sits inside the cavity here is another part to the speaker that's connected to what looks like it supports the spatial audio or it could be a sensor the main board is screwed onto the frame it has two shielding cans and some other discret components and on top of the cans there's a black thermal paste to distribute the heat under the main board there is a very thin Flex PCB that holds some of the small discrete components and sensors let's get these cans off the mainboard and see what's inside using the heat gun both cans come off quite easily it looks like there's a green thermal paste to distribute the heat more evenly across the processor and RAM it's interesting to see they have used two different types of thermal paste this could be due to cost and or thermal conductivity performance here you can see the new Snapdragon gen 1 smart glass chip as well as the onboard 32 GB memory we have another can on the other side of the mainboard PCB let's see if we can get that off it's much bigger than the two on the other side it took longer but I managed to get it off eventually now for the second arm once open we can see the right hand arm houses the battery it has a similar configuration to the left arm with the same speaker configuration but we also have a flex PCB under the battery running all the way along the arm looks like this could be the Bluetooth and wireless antenna it's sitting on an adhesive layer to keep it in place there are some connections from this Flex PCB to the frame which will be for the LED light and we have the same speaker design and cavity as we found on the left hand arm inside the frame we have a CNC aluminium part that was then screwed to the arm hinge it also Roots the flex PCB from the arm to the frame for the camera on the left hand side and the LED on the right that wasn't working let's get out the [Music] Dremel you can see how the connection for the charge pins are located inside the frame this is an over mile process so therefore making it impossible to take it out of the frame but what we can see is the microphone embedded into the right hand side of the nose piece cutting the frames in half will expose the contact of the charge pins from the nose piece through the frame and again on the other side we have the metal insert that's housing the support for the LED light let's quickly tear down the charging case to see what's going on there the case cover that holds the battery in PCB subassembly is very well secured inside the glasses and is quite an effort to get out what we have inside is a support frame that's holding the mainboard PCB and the battery there is a cylindrical battery that has a capacity of 334 milliamps it has a flying lead with a simple plug-in connector to the main board PCB and it looks like the battery protection circuit is inside the battery and it's also protected with some foam on the outside we also have the flex PCB for the two charge pins that connect the smart glasses when placed into the glass case and we can see a small micro switch which is pressed to get the charge status of the glasses on the bottom of the main board PCB there's a USBC which is located on the underside of the case for charging let's take a look at the design for manufacturer and analyze some of the manufacturing decisions made for these glasses all the frames and the arms are made from plastic and these are self- molded which means that they have no paint or post Pro processing cosmetic finishes this keeps the cost down and also means there are less issues with quality with the paint fading away or being chipped when the glasses are dropped we can also see that the cans for the mainboard PCB have slight recesses on the inside this is to ensure that there are clearance gaps from the top of the chip to the underside of the can and this is very important to prevent shorting or damaging the main IC and memory chips we also have a number of small Flex PC at varying thicknesses these are mainly used to maximize the internal space and root connectors and important sensors like proximity and light sensors for the glasses to fulfill the key functions inside the frames we see EMC shielding to meet the C and FCC requirements for wireless products where the arm meets the frame is a critical part as it needs to root the delicate Flex PCB from the main board assembly through to the camera module assembly we also have on the other side the same thing connecting the battery to the light LED as well as powering the main board PCB on the other side of the glasses it's very clever how they've used an insert molding process by creating a connection between the battery in the right hand arm all the way over to the main board PCB in the left you also have the charge connections that are insert molded into the nose piece that is used to connect and charge when placed into the case the batter is small enough to fit inside the right hand arm which has a capacity of 154 milliamps which is enough to power the smart glasses for up to 4 hours before needing recharge this is a very interesting battery size that we can expect to see in future smart glasses as this sets the standard for powering smart glasses alongside the new Snapdragon ar1 chipset the lenses are made from plastic and not glass which I expect is due to cost and is usual for typical sunglasses you can put in your own prescription lenses which means you can use them indoors and then you would expect a much higher scratch resistance performance we can now test the hardness of the different materials on the glasses using this durometer gauge which records the hardness of plastics this gives us an insight into the different grades of plastics used in a product let's take the hardness of the lenses and then the frame Plastics and then the lens of the camera and finally on the insert for the nose pads here you can see the different drometer measurements according to the shore hardness scale a cross-hatch test is used to determine paint adhesion and level of plastic structural strength of injection molded Parts this is a scratch test that creates even Cuts spread 1 to 3 mm apart here we are using a 10 to Blade with a 1 mm Gap this is our reference sample of a painted surface now we do the cross-hatch test on the plastic arm there doesn't seem to be any flaking that has been removed from the cross-hatch test confirming that these are indeed self- molded Plastics now let's try the pencil test on the lenses we start off with the H pencil then we used the 2H pencil then the 4H pencil and we can see the 4H scratches the lens so the lenses have a scratch resistance rating of 3H which is pretty good as most standard sunglasses have a 2H rating overall I'm very impressed with how the architecture of these glasses have been worked out they have managed to stay incredibly similar to the form factor of the original Rayband glasses which is a testament to their engineering meta have maximized Almost 100% of the internal space which is highly impressive considering the curvatures of the parts to follow the Rayband form factor the way the glasses are integrated with the charging case is also very smart and practical for obvious reasons these are not as robust as you would expect of other consumer electronics devices but this is understandable considering we are only on the second iteration they do not have any ipx rating for dust or water Ingress which is now the norm on all high-end smartphones I expect this will come in the next iterations of smart glasses now with the Snapdragon AR chipset these smart glasses are smaller lighter and more power efficient than previous versions I think these are a giant leap forward for smart glasses and they only see the next iterations being able to miniaturize even further it would also be nice to see further technology development around the speaker Technologies maybe you'll be able to remove them all together and replace them with bone conduction type Technologies making the glasses even smaller and lighter so for our quality and design for manufacturer score we are giving it a solid8 out of 10 very impressive from both meta and Rayban we are going to give away this blue jean way fa far repair to one of you all you have to do is subscribe to the channel and comment underneath this video with the words blue jean and we will choose one of you to receive the glasses for free if you enjoyed this video then give it a like and let us know what other products you would like us to tear down you can also see my product review of the Rayband metag glasses here thanks for watching and see you in the next one
