FOUP ID reading

In the semiconductor manufacturing process, accurate ID management of Front Opening Unified Pods (FOUPs) that transport wafers is extremely important for ensuring product traceability. However, the barcode labels on FOUPs, which are transported at high speeds by loaders and unloaders, are prone to scratches, dirt, and fading, causing minor equipment stoppages and reduced productivity due to reading errors.

KEYENCE's SR-2000 Series 1D/2D code reader solves this problem. The SR-2000 Series is equipped with a best-in-class reading engine and advanced correction functions. Even with scratched or damaged barcode labels or low-quality DPM (direct part marking), it instantly performs optimal image processing to achieve stable ID reading with an extremely high reading rate. Its wide field of view and long-range scanning capabilities allow it to flexibly handle variations in FOUP transport speed and position. Another feature is its high degree of installation freedom, making it easy to retrofit onto existing equipment. The introduction of the SR-2000 Series automates and stabilizes the FOUP ID reading process, contributing to stable operation and improved yield rates in semiconductor plants.
