PCBA stands for Printed Circuit Board Assembly. While a Printed Circuit Board (PCB) refers just to a non-conductive board designed for the purpose of connecting electronic components, PCBA refers to the complete electronic board after all of its components are assembled, mounted, and soldered. Cirtronics PCBA services consist of SMT, through-hole, selective soldering, automated optical inspection (AOI), flying probe, and a variety of board testing, including in-circuit testing (ICT) and environmental testing (ESS).
