Encapsulation of electronic modules
First Claim
1. A micromodule for the encapsulation of integrated circuits, comprising a punched metal grid, a strip of perforated dielectric screen transferred to the punched grid, the perforations of the screen covering conductive zones of the punched grid without covering interstices between these zones, an integrated circuit chip being placed in a perforation of the screen and being electrically connected to conductive zones located in other perforations of the strip.

Abstract
The disclosure concerns the encapsulation of integrated circuit chips, notably with a view to their being incorporated in a chip card. The encapsulation method comprises the formation of a pre-punched metallic conductive grid, the formation of a strip of pre-perforated plastic material, the transfer of a strip to the grid, the positioning of an integrated circuit chip in a perforation of the strip, and the formation of electrical connections between the chip and zones of the grid located in perforations of the strip. The perforations of the strip and the punched slots of the grid are arranged so that the strip covers and blocks all the interstices between conductors of the grid in the useful region corresponding to a module to be made. When a protecting resin is laid, it is confined and does not leak through the interstices of the grid. A plastic or metal ring defines the heightwise dimension of the micromodule.
