ABSTRACT:
A method of manufacturing a set of electronic modules for memory cards, using flip chips. A plurality of through holes are formed through an insulating sheet substrate to be filled with a conductive material for the purpose of establishing electrical continuity between first and second faces of the substrate. The first face is designed to receive contacts for making an electrical connection with an external connector, and the second face is designed to receive interconnection patterns for connection with a flip chip. The electrical contacts are silkscreened on the first face of the substrate, with the holes then being partially filled with a conductive ink. The interconnection patterns are silkscreened on the second face of the substrate, with the holes then being filled up with the ink. Flip chips are then mounted on the interconnection patterns.
