SAMSUNG A01/M01 CHARGING Board

Samsung A01 / M01 Charging Port Dock Connector Board

The charging board for the Samsung Galaxy A01 (SM-A015) and M01 (SM-M015) is a critical sub-component responsible for power delivery, data synchronization, and microphone functionality. This high-precision flex PCB assembly is designed to restore full connectivity to the device when the original port is loose, corroded, or damaged.

Product Specifications & Details

Key Technical Features

• Precision Micro-USB Port: Features reinforced steel casing to prevent the port from wobbling or breaking off the PCB after repeated cable insertions.

• High-Sensitivity Microphone: Includes a pre-installed digital silicon microphone to ensure crystal-clear voice transmission during calls.

• Signal Integrity: The board contains dedicated copper contact points for the coaxial antenna cable, ensuring no drop in 4G/LTE or Wi-Fi signal strength after replacement.

• IC Protection: Equipped with essential surface-mount components (capacitors and resistors) to help regulate voltage and protect the motherboard from minor power surges.

Common Symptoms This Part Fixes

Replacing the charging board is the standard solution for the following hardware issues:

1. Intermittent Charging: The phone only charges when the cable is held at a specific angle.

2. No PC Connection: The computer fails to recognize the device via USB, though it may still draw power.

3. Broken Pins: Physical debris or moisture has corroded the internal pins of the Micro-USB socket.

4. Microphone Failure: Callers cannot hear you, but you can hear them (indicating the primary bottom mic is faulty).

5. Signal Loss: Weak or no network bars caused by damaged antenna pads on the logic board sub-assembly.
