iPhone 8 battery mosfet missing
The main and only cause of this issue is a what we call as technician pry damage.
this missing component in the picture is a mosfet and it is located right above where the battery connects on to the logicboard and it is very easy to knock it off the board or damage it when trying to disconnect the battery.

iPhone 6S Plus Rear Camera was not working after It was Liquid Damaged.
upon board inspection and reading the values at rear camera fpc, noticed that FL3202 was bad and pads on both sides were lifted and burnt so we had to make this jumper to fix the rear camera issue.

Wola! Back camera back working
burnt backlight filter on iPad pro 12.9
The iPad Pro is known for no touch issues after screen replacements and that’s only if the battery is still connected and charged.
“Always disconnected the battery”
There are backlight filters which get damaged or burnt near the LCD FPC Connector even if the iPad is powered down.
How Do We Repair Them?
First, we remove the blown filters like the one in the picture above
then if the pads which the filter connects to are also damaged, we make micro jumpers from the nearest component or where the trace is exposed.
then we place and solder new filters on to the logicboard.
micro-jumpers done and new filter soldered
we put solder mask to make sure that nothing moves
It’s a logic board problem, but there is a 100% Permanent Fix
If you have an iPhone 6 Plus, it is very common for touch to stop working randomly. Even with a new screen, there will be no touch. This could also happen on iPhone 6 but not as common.
common symptoms: -Flickering Gray Bar on top -No touch -Ghost touching/random touching -random touching of the screen
How do We fix this:
Touch Disease issue is basically caused to the “M1” connection under the Meson IC Chip.
First, we desolder mason ic chip using a hot air
then we re-create “M1” trace pad that breaks or torn by making a micro jumper
then we reball the chip if still in intact condition or we replace it with a brand new chip and solder it back down on the board.
And Wola! Touch Works and Problem is resolved.
If you have an iPhone 7 or 7 Plus, you most likely are facing an iPhone Audio IC issue.
The way to test is to open Voice Memo and try recording if the app shows “Recording Failed” or “No Audio Devices” error then the Audio IC on your iPhone is in need of some attention.
