Board Connector for Xiaomi Redmi 4A

A Board Connector on the Xiaomi motherboard is a surface-mounted socket that provides the physical and electrical interface between the motherboard and a component's flex cable — such as the display, battery, camera, charging port, or fingerprint sensor. When a board connector is damaged or has broken pins, the connected component stops working even if the component itself is perfectly fine.

The faulty Board Connector is typically the one corresponding to the component that has stopped working. For example if the display stopped working after a drop, the display board connector is likely damaged. A technician can inspect all connectors under magnification on your Xiaomi to identify bent pins, corrosion, or lifted pads.

No. Board connectors are micro-SMD components soldered onto the Xiaomi motherboard. Replacement requires hot air rework equipment, precision flux, and board-level soldering skills. Incorrect removal lifts solder pads and causes irreparable motherboard damage.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Connectors that have been soldered are considered used and cannot be returned. For more information, check out SAHII's Return Policy.
