ABSTRACT:
A chip carrier including a connecting strip is supported by a thermally conductive spacer block under its center, which provides a mechanical connection to a circuit board. The external contact pads on the underside of the chip carrier are not bonded directly to traces on the board, but instead are bonded to the connecting strip which is formed from a polymer layer having conductive traces thereon. The conductive traces may be bonded to traces on the circuit board.
