Main board Flex Connector for Xiaomi Mi Mix 2s

The Main Board Flex Connector on your Xiaomi is the specific connector socket on the primary motherboard that receives the main inter-board flex cable — the cable that connects the motherboard to a critical secondary assembly such as the charging sub-board, display sub-board, or antenna board. It typically carries a higher number of signal lines than peripheral connectors and manages multiple function pathways simultaneously on your Xiaomi . Damage to it causes several functions to fail together rather than just one.

If multiple related functions fail simultaneously after a drop or repair — for example charging, microphone, and speaker stopping together — and the flex cable itself is confirmed undamaged and correctly seated, the Main Board Flex Connector on your Xiaomi motherboard is the likely fault. A technician can inspect under magnification for bent pins, a broken locking mechanism, or lifted pads.

Yes. Pin count, pitch, connector housing type, and PCB footprint are all model-specific. This listing is sourced for the Xiaomi motherboard only. An incorrect connector will not receive the flex cable correctly and risks damaging both the flex and the board.

No. This is a micro-SMD connector soldered onto the Xiaomi motherboard. Replacement requires hot air rework equipment, precision flux, and board-level soldering skills. Incorrect removal lifts the solder pads and causes irreparable damage to the motherboard.

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.
