Abstract:
A method for manufacturing a data medium in card form having at least one semiconductor memory element with a storage capacity of at least one megabit and having electroplated contacts for transmission of data between a data-processing system and the at least one semiconductor memory element of the data medium, comprising the steps of:providing a lead frame and mounting the at least one semiconductor memory element to a portion of the lead frame, another portion of said lead frame forming said electroplated outer contacts so that said electroplated outer contacts are integral with said lead frame; andfeeding said lead frame in tape form to an injection-molding process where the lead frame is encapsulated in a thermoplastic and wherein the electroplated contacts of the lead frame are provided along one side edge of a card formed by said thermoplastic encapsulation, the lead frame providing a resilient mounting support for the at least one memory chip as the lead frame is being encapsulated.
