Patent ID: 7176062

Claim:
A method of fabricating a memory card, comprising the steps of: a) providing a lead-frame carrier having opposed top and bottom sides, a plurality of contacts, and a plurality of traces; b) etching the lead-frame carrier in a manner wherein each of the traces defines a bottom trace surface, each of the contacts defines opposed top and bottom contact surfaces, the bottom trace surfaces and the bottom contact surfaces extend along respective ones of spaced, generally parallel planes, and the bottom trace surfaces and the top contact surfaces extend in generally co-planar relation to each other; c) attaching an integrated circuit die to the lead-frame carrier; d) electrically connecting the integrated circuit die to at least one of the traces; and e) partially encapsulating the lead-frame carrier and the integrated circuit die with an encapsulation such that the bottom contact surfaces are exposed in a bottom surface defined by the encapsulation.
