초록 ▼

A personal data card (10) is fabricated from a polymer thick-film circuit (12) formed of a polymer sheet (14) having a plurality of pads (16 and 17) and interconnecting paths (18) printed thereon with a copper-filled polymer ink. Each of a selected set of the pads (16) has a layer of nickel (22) applied to it, and then a layer of gold (24) applied above the nickel, to facilitate wire bonding of each of a plurality of aluminum leads (21), associated with a semiconductor die (19), to a corresponding pad. Use of such a polymer thick-film circuit (12) in the fabrication of the data card (10) reduces the cost of the card.

대표청구항 ▼

A method for fabricating a personal card comprising the steps of: forming a polymer thick-film circuit by printing a pattern of conductive pads and interconnecting paths on a polymer film with a conductive ink; applying a layer of nickel to selected pads on the film; applying a layer of gold above the nickel layer on said selected pads; wire bonding each of a plurality of leads associated with at least one semiconductor die to a corresponding one of said selected pads to which nickel and then gold is applied; and laminating at least one additional layer to the film. A personal data card comprising: a polymer thick-film circuit formed of a sheet of polymer film having a pattern of pads and interconnecting paths printed thereon with a conductive ink, each of a plurality of selected pads having a layer of nickel applied thereto and a layer of gold overlying the layer of nickel. at least one semiconductor die having a plurality of contacts each wire bonded by a lead to a corresponding one of said selected pads having nickel and then gold applied thereto; and at least one additional layer laminated to the polymer thick-film circuit.
