Abstract

Abstract A thin and flat integrated circuit assembly (10, 40) may be achieved by using a thin carrier (20) with shallow cavities (22, 24) for holding the integrated circuits (16) and/or discrete circuit components (14). The integrated circuits (16) and/or circuit components (14) may be friction fitted in the cavities (22, 24) or they may be secured therein by the use of adhesives and/or solder. Electrical connection between the integrated circuits (16) and circuit components (14) may be done with wire bonding, ribbon bonding, tape-automated bonding, lead frames, flip chip bonding, and/or conductive gluing of leads. The circuit assembly may then be accommodated into a credit card-sized packaging with standard dimensions set by the International Standards Organization.
