Abstract

Abstract An apparatus for mounting ceramic chip carrier devices onto printed circuit boards. The apparatus includes an adapter assembly with contact terminals, which is positioned and secured by a plastic frame to the circuit board, a washer member containing magnetically aligned electrically conductive particles, and a cover or clip to maintain each contact terminal in engagement with the corresponding conductive particles to electrically couple the adapter assembly and printed circuit board with a clip carrier device. This design incorporates features of both metal and elastomeric contact systems. Alternative apparatus for mounting integrated circuit chips onto printed circuit borads is also disclosed. Such apparatus includes an insulating frame, an elastomeric washer member containing electrically conductive particles, and a cover for holding the assemblage together. These designs may require a small number of holes in the circuit board or may provide for surface mounting instead.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 100 words
An apparatus for mounting a circuit component which has terminals onto a circuit board, CHARACTERIZED BY a socket member having a plurality of electrical contact members formed around at least one edge thereof for mounting on said circuit board; a washer member adapted for positioning on said socket member and for positioning said circuit component thereon, and having conductive paths formed therein to make electrical contact between said socket member's contact members and said circuit component terminals; and means for engaging said socket member and maintaining said circuit component terminals in engagement with said conductive paths of said washer member.
Claim 2
Independent Claim 100 words
An apparatus for mounting a circuit component which has terminals onto a circuit board, CHARACTERIZED BY a socket member having a plurality of electrical contact members formed around at least one edge thereof for mounting on said circuit board; a washer member adapted for positioning on said socket member and for positioning said circuit component thereon, and having conductive paths formed therein to make electrical contact between said socket member's contact members and said circuit component terminals; and means for engaging said socket member and maintaining said circuit component terminals in engagement with said conductive paths of said washer member.
