If you’ve ever had to repair an iPhone for a friend, you’ll know they have a ridiculous number of screws. Most companies standardize screws in their products, but since Apple doesn’t expect you to fix a phone yourself You see, each of these screws is different.

The red ones are 1.7mm long, the yellow one, 1.3mm, and the orange one, 1.2mm. Guess what happens if you install either red or yellow screws into the orange spot, since your eyesight isn’t good enough to notice a 0.1mm difference? Subtitle indonesia mongol the rise of genghis khan youtube.

The screw will cut into the PCB and break several 50 micron traces, as shown in the picture above, causing a blue screen error on the phone. [Sam Schmidt] is the owner of a repair outfit called iRepairNational, and he and his team spent a day trying to figure out the problem – it’s not exactly easy to spot. They’ve managed to repair it by cutting thin strips of copper foil (the width of a human hair) and floating it into place using the surface tension of the flux they were using for soldering.

The pentalobe security screw (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, but not limited to, Apple in their products. Pentalobe screws were adopted by Apple starting in 2009, when they were. P2, TS1, PL1, 0.8 mm, iPhone 4 (Late), 4S, 5, 5C, 5S, 6, 6 Plus, 6S, 6S Plus,.

On average it takes them around 2 hours to do the repair, though they’ve done a few in just under an hour. Since discovering and sharing the problem, they’ve had customers around the world sending in phones for repair – often at the fault of someone else trying to repair something completely different in the phone, and then using the wrong screw as they put it all back together. • • • • Posted in, Tagged,,,, Post navigation.

“Why would this be a “trap”?” Because in practically every other similar repair in the world a 0.1mm difference in screw height would not cut through several incredibly tiny traces and damage the unit. Nearly all electronics I’ve pulled apart (including plenty of phones) do not have screws which bottom out on circuit boards in a way that could cut something critical. This is a trap in that it is causing people who have experience with repairing stuff to actually damage devices in a practically unheard of way. >It’s hardly a nasty trap to use different length screws in a device! Well then, if this wasn’t a deliberate trap for 3rd party repair teams, Apple should now document the difference in a tech bulletin, and then anodize or parkerize or plate the screw differently from now on to avoid future mixups. But this is Apple, and they probably feel a little violated that you dared to intrude in the inside of their design anyway, because their ToS leaves little doubt that they don’t think you really own your own phone. Don’t hold your breath.

Don’t buy Apple. Differing screw lengths is nothing new. When I’m disassembling something for which I know (or suspect) this is an issue and want to be certain I reassemble it correctly, I take a photo of the device and print it out, enlarged or shrunk as necessary. Then as I remove each screw, I Scotch tape it onto the appropriate place on the photo. Repeat for each layer of disassembly.
