1. Product Introduction
We provide full one-stop PCB assembly services for automotive EPS (Electric Power Steering) devices, covering PCB fabrication, automotive component sourcing, precision SMT/DIP soldering, automated functional testing and protective coating.
Our EPS PCBA complies with strict automotive IATF16949 standards. We design high-reliability circuit boards for EPS control units, torque sensor signal boards, motor drive boards and CAN/LIN communication modules. The assemblies adopt anti-vibration layout, low-temperature resistant components and ESD shielding circuits to adapt to complex vehicle operating environments. All PCBA pass vibration, thermal cycling, salt spray and full signal aging tests before delivery. Custom circuit modification, firmware matching and conformal coating are available for prototype trial and mass automotive production.
