Brake System Device PCB

A 2-layer heavy copper PCB built for automotive brake control modules, 2.0±0.15mm thick with OSP surface finish. The thick copper traces handle the high inrush currents required by solenoid valves, ABS pumps, and brake-by-wire actuators while keeping junction temperatures low under continuous duty. The board carries control signals between brake sensors, ECU logic, and high-current drive stages, so trace impedance and thermal balance are tightly controlled to prevent voltage drop and signal distortion during braking events. OSP finish provides flat, reliable solder joints for SMT assembly without compromising contact resistance over the lifetime of the vehicle. Typical platforms include passenger cars, light commercial vehicles, and EV traction systems where braking reliability is a safety-critical requirement under vibration, humidity, and wide temperature swings.
