Inconsistencies in manual or automated soldering may result in faulty connections between components on PCBs and cause short circuits when the solder bridges extra components. In other cases, these inconsistencies result in open circuits or intermittent electrical connections. Failures often go undetected until final testing, leading to increased scrap, slowed throughput and high quality control costs.
Cognex vision systems with specialized illumination and pattern recognition tools automatically inspect solder joint connections for missing or excess solder. Pattern recognition tools are used to analyze the shape of the solder to ensure it meets rigorous tolerances.
