ABSTRACT:
A card-independent method of forming a module for subsequent attachment to a card body includes increasing both the area and the height of contact pads on an integrated circuit die and includes forming a leadframe in which contact sites are electrically connected to the contact pads of the die by Z-axis epoxy. The epoxy is unidirectionally conductive, so that the epoxy as a mechanical link, an electrical link, and acts as an overcoating of the active side of the die A die-alignment layer having a center cavity properly positions the contact pads of the die relative to contact sites of the leadframe.
