Product Case — Desktop Fans: Quiet, Energy-Saving PCBA Motor Control

A desktop fan looks simple, but its PCB quietly handles motor speed control, oscillation, timing and dial or touch input. The right board keeps the motor quiet, the speeds stable and the power draw low — the qualities that decide whether a fan feels premium or cheap.

XUNFEI designed and manufactured control boards for a family of real desktop fans: retro yellow and green models, a compact white mini fan and a modern red circulating fan. Every board manages motor drive, speed regulation and safety protection, with layout tuned to minimize electrical noise and maximize energy efficiency.

The control PCBA below is a typical example of what goes inside these fans — a compact, high-reliability board that keeps operation quiet and energy consumption low.

Our mature high-multilayer and HDI board manufacturing capabilities, backed by strict quality control, let us produce these control boards at scale with consistent quality — every unit leaves the factory working exactly the same.
