Description

OPPO A5 2020/A9 2020 OG CHARGING Board

 

The charging board for the OPPO A5 2020 and A9 2020 is a critical sub-board component (often called the secondary PCB) that handles power delivery, data syncing, and audio connectivity. This "OG" (Original Grade) quality board ensures compatibility with VOOC Flash Charge protocols and maintains signal integrity for the cellular antenna.

Product Overview

The board is a direct replacement for units experiencing issues with loose ports, slow charging, or microphone failure. Unlike low-quality aftermarket clones, the OG version features all necessary ICs (Integrated Circuits) to protect against overvoltage and ensure stable data transfer.

Detailed Component Breakdown

1. USB Type-C Charging Port

The heart of the board is the Type-C port. The OG version uses reinforced soldering points to prevent the port from lifting off the PCB after repeated use. It supports both power intake and OTG (On-The-Go) data functions.

2. Primary Microphone

Located at the bottom of the board, this MEMS microphone is responsible for your voice during calls and voice recordings. OG boards use high-sensitivity microphones to ensure clear audio without the "muffled" sound often found in cheap replacements.

3. Antenna Signal Logic

The board contains gold-plated contact points that connect to the phone's frame or antenna wire. This is vital for maintaining 4G/LTE signal strength.

4. Circuit Protection

Original-grade boards include:

  • Over-current Protection: Prevents the battery from overheating during surges.

  • ESD Shielding: Protects the delicate internal components from static electricity.
