Company profile
Listed EMS company (000021) with manufacturing bases in Shenzhen, Huizhou and Dongguan; its PCBA capability includes conformal coating, potting and SPI / AOI / X-ray / ICT / FCT testing for industrial-control and power-control boards.
Where it fits in motor manufacturing
- Hall Sensor Board (PCBA)
The small board at the stator end that carries three Hall ICs to sense rotor position for commutation. Hall position accuracy directly sets commutation timing, so placement, soldering and mounting on the stator are the critical points.

- BLDC Driver Board (PCBA), 24 V sensorless FOC
The driver built into the motor's rear end cap: an MCU running sensorless field-oriented control, a three-phase gate driver and six power MOSFETs switch the motor phases from the 24 V supply. Heat from the MOSFETs, solder voiding under their pads, EMC and full functional testing decide its reliability.
