The Redmi Note 6 and Note 6 Pro utilize a Sub-PCB (Printed Circuit Board), commonly referred to as the "Charging Board" or "CC Board." This component is critical because it doesn't just handle power; it serves as a bridge for the microphone and cellular antenna signals.
Below is a detailed technical description and specification breakdown in a tabular format.

1. Charging & Data Sync
The primary role of this board is to house the Micro-USB port. It facilitates the flow of electricity to the BN48 battery and allows for high-speed data syncing with computers. Genuine boards include overvoltage protection (OVP) components to prevent short circuits.
2. Audio & Communication
The Primary Microphone is soldered directly onto this board. If people cannot hear you during a phone call, it is usually this board that needs replacement. It also features the connection point for the Antenna RF cable, which is vital for 4G/LTE signal stability.
3. Symptom Checklist (When to Replace)
No Charging: The phone doesn't respond when the cable is plugged in.
Loose Connection: You have to hold the cable at a specific angle to charge.
Mic Issues: Callers cannot hear your voice, but speakerphone works (the speakerphone uses a different mic).
Signal Drop: Weak or no network signal after the phone has been dropped or repaired poorly.
Slow Charging: The phone takes 5+ hours to charge due to worn-out carbon contacts in the port.
