Trouble troubles：

An iPhone 6S dropped and then it doesn't boot. Disassemble the iPhone with phone opening tools , and then put it connects to DC power supply , it shows big short circuit. After measure it, we found the PP_VCC_MAIN is short circuit. Many of dropped iPhones PP_VCC_MAIN filter capacitor will be short circuit.

Remove the iPhone motherboard , and observe it under the microscope , we found the capacitance C5283_RF next to iPhone WI-FI chip turned gray, it differs greatly from the color of the capacitor next to it. This capacitance is the filter capacitor of PP_VCC_MAIN.

Now we directly remove this capacitor, and measure it again with multimeter, the resistance value is back to normal. As shown in picture 10-6-3

Connect it to DC power supply again, and boot it, now it shows normal, the iPhone 6s can be turned on. The repairs end!

Customer delivered a iPhone X and described the fault is not to boot after the phone drop accidentally. It reports error 56 when restore the iPhone X. How to repair this fault? Because iPhone X is the two board connected through the middle column, it is easy to drop the point. It may be that the solder points from NFC chip to the CPU part have fell off. Take apart the iPhone X by iPhone Screwdriver Repair Tools , take the upper board off the main board, when separate the main board we see a row of points have fell off. Picture 19-3-1 Look at the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56. Picture 19-3-2 Then the tin of the middle column is repaired by iPhone X BGA reballing stencil , and the AP part is welded bac...

After checking, we found signs of corrosion in the fingerprint socket, and then detect MESA_TO_BOOST_EN_CONN. Use Fluke 15B+ Digital Multimeter  to measure the diode data of PP16V5_MESA_CONN fingerprint boost boot signal and 16.5V, the data is normal. Observe the iPhone PCB board carefully under the VGA Camera 7-45X Trinocular Stereo Microscope  , we found something else. The bottom pin was severely corroded after the corrosion was removed from the fingerprint boost U4040. A2 pin PP_VCC_MAIN is disconn...
