What's Automotive PCBA?
Automotive PCBA, or automotive printed circuit board assembly, is a finished product formed by assembling electronic components onto automotive printed circuit boards (PCBs) through welding and other processes. It is the core carrier of automotive electronic systems and is widely used in automotive power systems, body control, safety assistance, infotainment, and autonomous driving systems, such as engine control units, battery management systems, and anti-lock braking systems.
