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 chip carrier device. This design incorporates features of both metal and elastomeric contact systems. Alternative apparatus for mounting integrated circuit chips onto printed circuit boards is also disclosed. Such apparatus includes an insulating frame, an elastomeric washer member containing electrically conductive particles, and a cover for holding assemblage together. These designs may require a small number of holes in the circuit board or may provide for surface mounting instead.
