SMT Assembly Services for Automotive Electronic
♦ What Is SMT Assembly Service?
SMT Assembly (Surface Mount Technology Assembly) is a modern method of mounting electronic components directly onto the surface of a printed circuit board (PCB). It is the most widely used PCB assembly technique today, replacing traditional through-hole technology (THT) in most applications due to its efficiency, precision, and ability to support miniaturized and high-density designs.
