SPI is a critical quality control step in the SMT manufacturing process. It uses advanced imaging or laser technology to inspect solder paste applied to PCB pads. Inspectors verify the amount, placement, and uniformity of the solder paste, and detect defects such as insufficient solder paste, misalignment, or bridging. By detecting problems early, SPI inspection can prevent soldering failures, ensure reliable component bonding, and improve the overall production quality of electronic assemblies.
