Changing the Rules for PCB Testing

Electronics customers require greater test flexibility to address the growing trend towards high-mix, low-volume printed circuit board (PCB) production. Sterner Automation is pleased to introduce the igentic® 421t, the next generation of automated test solution specially engineered to address these challenges. The igentic® 421t provides the flexibility, reliability and efficiency needed in one standard platform, allowing our customers to test multiple PCB's and significantly reduce individual product testing costs.
