Abstract:
A sensor-package arrangement comprising,a case of insulating material, said case having walls which define an internal cavity, said cavity having at least one internal surface with conductive material thereon and having a conductive channel placed in one of said walls between an external conductive contact on the exterior of said case and said conductive material of said internal surface,a sensor die disposed between walls in said cavity of said case, said sensor die having at least one die electrical contact,an electrically conductive spring placed between said conductive material of said internal surface and said die electrical contact,whereby said spring resiliently forces said sensor die against at least one of said walls of said cavity and completes a conductive path which includes said conductive channel from said external conductive contact to said die electrical contact,said case having a conductive top surface and a second conductive channel placed in one of said walls between a second external conductive contact on the exterior of said case and said conductive top surface,said sensor die having top and bottom sides with said bottom side facing downwardly in said cavity and said top side facing upwardly, said top side having a second electrical surface,a conductive lid to which a downwardly facing electrically conductive top spring is attached, said lid being electrically connected while being physically secured to said top surface of said case,said conductive top spring arranged and designed to force said sensor die downwardly in said cavity while contacting said second electrical surface,whereby said lid and said attached secured spring simultaneously close said cavity, force said sensor die into said cavity, and complete an electrically conductive path from said second external conductive contact to said second electrical surface of said die.
