Each touch IC is uniquely paired with the logic board of the iPhone it's installed in. By transferring the original touch IC to the new display assembly, you maintain compatibility and prevent potential issues with touch functionality.
Overall, transferring the touch IC to a new display assembly ensures seamless compatibility, preserves device functionality, and can be a more practical solution in many cases of display replacement on iPhones.

I have some of those Wylie sheets and they are incredible. They work up to around 400c I believe.

[@FIXDPHONES]

They are a game changer from all the Kapton tape and shields I used to use

[@CozyBread]

Excellent video. Where do you get the heat-resistant foam sheet from?

[@FIXDPHONES]

They are called Wylie sheets, and MobileSentrix should be carrying them soon.

Nice instructive video, but you should also show your technique to prepare the new display if the IC is still on. I am always afraid to grind too much and I haven't found a perfect technique yet

Will the iPhone 15 Pro Max, 15 Pro, 15 work without the IC chip? I know it restores true tone (touch calibrations) and gets rid of "Unrecognized Part pop-up" but is it mandatory to keep the screens touch functioning or keep from black screening? What about the iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max? I ask because I've been given the impression it should, even MobileSentrix support told me it would work without it just continue getting pop-up message and no true tone. No other issues (specifically on 14 Plus). Here's my story: I had an iPhone 14 Plus brought to me and installed an aftermarket AQ7 screen from Mobile Sentrix without transferring the IC chip from the original screen. It worked for a day, but then the screen went completely black. I could still feel vibrations when flipping the loud/vibration switch, so the phone was still on, but the screen had no picture. I took the screen off and put the original back on, but left Face ID unplugged. This caused power issues, with the phone powering on and off by itself every 2 minutes. Once I plugged Face ID back in, everything started working fine with the old screen. It seems to be that I got just a bad screen unless it was the IC so Mobile Sentrix is sending a replacement AQ7 screen. I don’t plan on transferring the IC chip (I never have on previous iPhone repairs, usually 12s and 11s but I've done almost all kinds of iPhones new and old with your AQ7 and XO7 screens without any issues and I nearly never transfer IC chips since my soldering iron broke in December). Will the new aftermarket screen they’re sending likely work?

Ok,no IC on the screen, good, but the fact that the flex cable is not glued down and being hard to unglue, that’s a bit exaggerated. A little bit of alcohol and prying out with plastic pry tool is all it takes. Easy.

Hey mate, what airflow do you use? My temp is 230 and air flow 66 but it just wouldn’t melt the solder balls. Even with a large nozzle.

[@FIXDPHONES]

You can go up into the 300’s you just have to be careful. Try using a lower melting solder when reballing.

I am from saudi arabia. I have my phone mi 11 lite 5g. Phone working but display not working can you solve them?

[@gergelysoki1705]

how is the mechanic flux, is it good?

[@pcwaves]

Tried it, it's OK and very sticky. I used AMTech and now one from Maant which I am happy with
