Manufacturing method for an integrated circuit card
First Claim
1. A method of manufacturing an electronic card having an electrically insulating card support provided with a cavity for accommodating an integrated circuit and, on one surface of said support, metal contact pads electrically connected to contacts of said integrated circuit, said method comprising the steps of:
- (i) the application of electrical conductor tracks, all provided against the bottom and the lateral walls of said cavity and each connected to one of said metal contact pads arranged on the surface of the support which comprises said cavity,(ii) the realisation of electrical connections interconnecting the contacts of the integrated circuit positioned in the cavity and said conductor tracks at the bottom of the cavity, and(iii) filling up of said cavity with a protective resin which is subsequently polymerized.

Abstract
The electronic card comprises an electrically insulating card support provided with a cavity for accommodating an integrated circuit and, on one surface, with metal contact pads which are electrically connected to contacts of the integrated circuit. The invention comprises the steps of: (i) the application by an MID technique (Moulded Interconnection Devices) of electrical conductor tracks, all arranged on the bottom and the lateral walls of the cavity, and each connected to one of the metal contact pads arranged on the surface of the support which comprises the cavity, (ii) the realization of electrical connections connecting the contacts of the integrated circuit arranged in the cavity to the conductor tracks on the bottom of the cavity, and (iii) filling up of the cavity with a protective resin which is subsequently polymerized.
