A Control Board PCBA is a critical printed circuit board assembly designed to manage and execute operational commands in electronic systems. It integrates microcontrollers (e.g., ARM Cortex-M) or FPGAs to process input signals from sensors, switches, or communication modules (UART, CAN, Wi-Fi). Built on FR-4 or aluminum-core substrates, it ensures thermal stability and supports 1–3 oz copper traces for power distribution and signal integrity. Compliance with IPC-6012 Class 3 and RoHS guarantees reliability in harsh environments, while ENIG/HASL surface finishes enhance corrosion resistance and solder joint durability. Applications span industrial motor controllers, automotive ECUs, and smart home devices, where rigorous testing (ICT, FCT) ensures fault tolerance and operational precision
