Patent ID: 7795720

Claim:
An inversely alternate stacked structure of IC modules, comprising: at least one IC module, having a substrate, at least an IC chip and a molding body, wherein the substrate has an inner surface and an outer surface, at least an external contact pad is provided at one end of the outer surface, at least a switch contact pad is provided at the other end of the outer surface, the external contact pad and the switch contact pad are disposed in an inversely symmetrical manner and are electrically connected, and the molding body is formed on the inner surface of the substrate to seal the IC chip; and at least a spring strip set having at least a non-flat structure, wherein the external contact pad of one of the IC modules is electrically connected with the switch contact pad of the other IC module by electrically contacting with the non-flat structure of the spring strip set so that the IC modules is in the form of an inversely alternate stacked structure.
