Surface Mount Technology, also known as SMT (Surface Mounting Technology), is a process where surface-mounted components are directly soldered onto specified positions on a printed circuit board (PCB) without the need to drill holes for through-hole mounting. Currently, SMT is widely used in the manufacturing of PCBA boards for electronic products, replacing traditional through-hole technology. SMT improves product reliability and performance while reducing production costs, leading to significant transformations in electronic products, both in consumer electronics and advanced industrial electronic product sectors.
