ABSTRACT:
Packaging of discrete semiconductor devices is improved by dimpling metal caps prior to assembly onto headers and welding.
The dimpled caps provide a friction fit to the headers, whereby fewer assembled, but unwelded packages separate during handling. The dimples are more economical and more reliable than prior art crimps which perform a similar function.
