iPhone 6 Plus Touch IC Repair
If you’re part of the cell phone repair community, then I’m sure you already know about the iPhone 6 plus touch ic epidemic. Here’s my take on the problem.
In Apple’s search for the biggest, thinnest, most durable, longest lasting, and sleekest iPhone, they totally neglected the the rigidity of the iPhone 6 plus and the fact that it bends pretty easily. Since the logic board is held pretty firmly in place onto the frame with many screws, whatever bending that takes place with the frame also bends the logic board. With the bending of the logic board, the ball grid array (BGA) chips on the logic board also seem to break from it leading to what the repair community knows as “touch IC disease”.
What is “touch IC disease”? There are two chips on the iPhone 6 plus logic board that handle the touch functionality. The two chips are called Meson and Cumulus to the repair community. U2401 (Cumulus) and U2402 (Meson) as they are known in the schematics.
It seems as though some of the balls under the BGA chip break free from the logic board when the frame of the iPhone bends thus causing intermittent “no touch” problems. This problem has been essentially an epidemic. It’s happening at such an outstanding rate that most microsoldering repair shops can’t keep up with the demand to repair.
Apple really should issue a recall on the problem or perhaps, offer to fix the problem for free.
So, the way to fix this “touch ic” problem is to remove the two chips using heat and put new ones on. Most of the time, the problem goes away once this has been done. I’ve done dozens of these repairs in my shop. Here’s a video of one of my repairs:
