An SMT SPI machine is a key quality-control tool in SMT production lines. Positioned post-solder paste printing, it uses high-resolution optical scanning to check paste volume, position, and uniformity on PCBs. By detecting defects like bridges or insufficient paste early, it prevents costly reflow issues, minimizes waste, and ensures consistent, reliable soldering for electronic components.
