SAMSUNG A10S CHARGING Board

The Samsung Galaxy A10s (SM-A107) Charging Board, also known as the Sub-PCB or CC Board, is a critical component that acts as the communication and power gateway for the device. Unlike the standard A10, the A10s uses a specific layout that integrates the charging port, microphone, and antenna connections on a single replaceable module.

Below is a detailed technical breakdown in a tabular format.

1. Micro-USB 2.0 Port

The board features a precision-soldered Micro-USB port. High-quality versions include reinforced solder joints at the anchor points to prevent the port from breaking away from the PCB due to the stress of daily cable insertion.

2. Primary Voice Microphone

This module houses the phone's primary microphone. 

3. RF Signal Hub

The golden circular terminal on the board is the Antenna RF Connector. A damaged or low-quality board often results in a "No Service" or "Emergency Calls Only"

• No Charging: The device does not respond to any charger or cable.

• Slow Charging: The phone takes 6+ hours to charge or shows a "slow charging" notification.

• Mic Failure: Callers report they can't hear you unless you use headphones or speakerphone.

• Network Issues: Weak signal bars or intermittent 4G/LTE connectivity.

• Loose Port: The cable feels loose or falls out easily, or only charges at a specific angle.
