Medical Mother Board and SMT SMD PCB Assembly
♦ What Is SMT Assembly?
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.
♦ What Is SMD?
An SMD is an electronic component designed specifically for surface mounting (SMT). These components have small metal pads or terminations instead of long leads.
♦ Common Challenges in SMT/SMD Assembly:
Solutions:
✔ Proper stencil design (for accurate solder paste application)
✔ Reflow profile optimization (temperature control)
✔ AOI & X-ray inspection (for defect detection)
