A manufacturer of semiconductor testing machinery was having quality rejections on wafer test sockets due to burrs inside small diameter holes. They needed a stiff, dimensionally stable plastic material that would allow for smooth, clean machined surfaces. The design engineer worked with Curbell’s technical team to identify a replacement material that would meet their needs. Stiff, Dimensionally Stable Plastic Curbell suggested that they evaluate TECAPEEK® CMF, ceramic filled PEEK for the application. The material performed well and it solved the problem.
