LED & Power Supply PCBA — Drivers, Switching Power and Display Boards

Power electronics handle the most demanding currents and heat. A well-designed power board keeps conversion efficient and temperatures under control. XUNFEI's power boards use heavy copper, optimized thermal paths and EMI-friendly layout to keep noise low and service life long.

We produce switching power supply boards, LED driver boards, display control boards and inverter boards, with transformer, heatsink and EMI filter design support. Every board is validated for thermal and electromagnetic performance before delivery.

A circuit board's quality and performance directly shape how well the whole system runs. Our engineers control signal routing, heat dissipation and anti-interference from the first drawing, while our mature high-multilayer and HDI board manufacturing capabilities — backed by strict quality control — ensure consistent quality and high reliability from prototype to volume production.

From board to light: our driver boards power finished LED products such as this panel light, delivering efficient, stable illumination that lasts for years of continuous use.
