Minimizing load-board damage

摘要

In a study titled "Spring Probe PCB Pad Wear Analysis" presented at the 2010 BiTS Workshop (March 7-10, Phoenix, AZ), Valts Treibergs and Chris Cuda of Multitest's ECT Interface Product Division analyzed the effects of spring probes on load-board pads in an effort to extend the life of $10,000-and-up load boards. Their controlled study of spring-probe geometries found that the radius-flat-tip PCB-side geometry displaced the least amount of surface gold plating on load-board pads of 0.5-mm pitch and larger.
