Common Motherboard/PCB-Level Failure Issues in Smartphones
The printed circuit board (PCB), sometimes known as the motherboard, is the central component of a smartphone. It ensures smooth operation by connecting all essential parts, including the processor, memory, power circuits, and sensors. Faults at this level, however, have the potential to cause major performance problems or even device failure. Let us discuss the most typical motherboard issues along with their root causes. Failures of Power and Charging ICs The power management IC (PMIC), which controls power distribution, is one of the most common problems. This area may be damaged or malfunctioning, which could stop the phone from turning on, cause random shutdowns, or cause the battery to deplete quickly. Likewise, delayed or nonexistent charging, overheating, or charging pauses might be caused by a malfunctioning charging integrated circuit.This can happen to any device regardless of its brand.
