Large-scale EMS SMT Line QR Code Scanning Upgrade Solution

A major electronics contract manufacturer's SMT line faces challenges with high component density and micro-sized codes. Traditional scanners cannot reliably read QR codes smaller than 0.5mil, causing frequent production stoppages for manual code re-application, which severely impacts efficiency.

Yuanjie Technology provided a high-precision embedded 2D barcode reader that supports decoding of 0.5mil micro-barcode formats, optimized for high-speed production lines. The compact module fits easily into the limited space within SMT equipment and integrates seamlessly with existing MES systems.

After the upgrade, recognition success rate increased from 92% to 99.8%, and production line downtime decreased by 70%. Customers report excellent device stability and low maintenance costs. Deployment across additional production lines is now planned.
