In SMT processes, precise dimensional control is essential to ensure that PCBs, components, and carriers meet required specifications before placement and assembly. Variations in width can cause misalignment, pick-and-place errors, soldering defects, and downstream assembly issues.

A 2D smart vision camera enables in-line width measurement by capturing high-resolution images of SMT boards or components and analyzing edge-to-edge dimensions in real time. It verifies whether each item falls within defined tolerance limits during production flow, allowing immediate rejection or correction. This improves dimensional accuracy, reduces assembly defects, and ensures stable quality control in high-speed SMT manufacturing environments.
