[0002] PCBA, or printed circuit board assembly, is a crucial component in electronic products. It consists of a printed circuit board (PCB) and soldered electronic components. After undergoing soldering, assembly, and testing, it forms the functional module of a complete electronic product. PCBA is widely used in a variety of electronic products, including consumer electronics, industrial control equipment, medical devices, automotive electronics, and communications equipment. Its design and manufacturing quality directly impact the performance and reliability of the entire product.
