What does a mobile phone motherboard look like? The mobile phone motherboard is the main circuit board in the mobile phone.
There are three main parts on the mobile phone motherboard: baseband chip, power management chip, F processor responsible for encoding,
RF power management chip, responsible for transmission and reception: other CPUs, memory controllers, touch screens, Bluetooth WiFi sensors, etc.

There are also some microphones, headphones, speakers, cameras, screens, interfaces, etc.
These things are all welded on a circuit board, which is called the mobile phone motherboard.
Function of mobile phone motherboard: integrated mobile phone operation management.

The extension cord also has a flat cable connected to the mobile phone motherboard.
When the mobile phone is turned on, it can send a signal at the bottom of the screen and produce a black line. Causes of mobile phone motherboard failure:
The first major cause of mobile phone motherboard failure is liquid intrusion, including water ingress, accidentally falling into other liquids;
Using the mobile phone in extreme environments; electrostatic breakdown of motherboard components;
Accidentally damaging the motherboard and increasing instantaneous current,
Which is mainly caused by faults such as battery short circuit; using an unmatched charger
