The Solder Paste Inspection System (SPI) is critical in electronics manufacturing. It checks the volume, area, height, and misalignment of solder paste on the printed circuit board (PCB) before component placement and reflow soldering. It uses automated optical inspection or 3D inspection technology to effectively prevent defects such as solder bridging. By ensuring that solder paste is properly applied, SPI can improve solder joint reliability and reduce production costs.
