SPI (Solder Paste Inspection) is a critical quality control process in SMT manufacturing that verifies the accuracy of solder paste deposition before component placement. Using high-resolution 3D optical scanning, SPI systems measure paste volume, height, area, and alignment with micron-level precision (typically ±3μm). This non-contact inspection detects defects like insufficient paste, bridging, or misalignment, preventing soldering failures downstream. Modern SPI machines integrate AI-powered defect classification and real-time data feedback to stencil printers, reducing rework by up to 90%. Essential for high-density PCBs with fine-pitch components (e.g., 01005 or 0.3mm BGA), SPI ensures process consistency and improves first-pass yield in automotive, medical, and consumer electronics production.
