Quad Density Pin Card for Enhanced Throughput and Reliability
应用文章
This application note addresses the evolving challenges in testing modern and densely packed Printed Circuit Board Assemblies (PCBAs) and introduces the Quad Density (QD) pin card as a groundbreaking solution. As electronic systems grow in complexity, the need for comprehensive testing becomes crucial. The current limitations of double-density pin cards prompt the development of the QD pin card, which offers 320 test pins on a single board, more than doubling its predecessor's capabilities. The QD pin card not only enhances test pin capacity but also introduces features like built-in discharge circuits and temperature sensors to optimize testing efficiency. Backward compatibility ensures seamless integration with older testing systems, and electronic serial number storage facilitates easy identification and troubleshooting.
