Electronics
Application #10: PCB Solder Joint Inspection
Challenge: Solder defects can be microscopic. Bridges, insufficient solder, tombstoning, and cold joints can all create latent failures in compact assemblies.
Solution: Automated optical inspection systems compare each board against inspection criteria and detect solder anomalies at scale. They help electronics manufacturers inspect dense boards more consistently while shortening feedback loops to the SMT process.
