Industrial Automation & Control PCBA — PLC, Servo and HMI Boards for Demanding Environments

Industrial control systems run around the clock in plants full of electromagnetic noise, fluctuating power and extreme temperatures. The printed circuit board is the nervous system of every machine: it must carry stable signals while suppressing interference that could cause false triggers or communication errors. Careful grounding, isolation and high-creepage layout are the difference between a controller that fails and one that runs for years.

XUNFEI designs and manufactures boards for PLC controllers, servo drives, variable frequency drives, industrial gateways, sensor modules, machine vision cards, equipment controllers, data acquisition boards and industrial HMI panels. Wide-temperature-rated materials, optional conformal coating and vibration-tolerant mounting keep every board dependable in the harshest workshops.

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 the bare board to the finished module, XUNFEI supports the full journey. The complete PLC controller module below shows our control board working inside a rugged DIN-rail housing — a ready-to-ship product built on our PCB.
