INTEGRATED CIRCUIT CHIP CARRIER

摘要

Known chip carriers are usually made of ceramic material which is expensive and can give rise to problems due to differential expansion when bonded to conventional epoxy/glass printed circuit board. …The invention provides a chip carrier comprising a base (10) of plastics material and a side wall (22) of plastics material, extending around the periphery of the chip carrier so as to define a chip mounting cavity. Conductive tracks extend from first connecting points (12) in the cavity to second connecting points (18) on the periphery of the chip carrier.
