Title: METHOD FOR MAKING AN ANISOTROPIC CONDUCTIVE COATING WITH CONDUCTIVE INSERTS
Abstract:
The invention concerns a method for making an anisotropic conductive coating comprising an insulating film (26) perforated with holes wherein are housed conductive inserts (28) overlapping on one side of the insulating film with first ends, from a substrate (20) whereof one surface comprises cells corresponding to the distribution of inserts on the insulating film, the cells matching in recessed form the first ends of the inserts. The method comprises the following steps: a) using a substrate (20) with cells having pointed tips; b) producing the insulating film (26) above the substrate (20) with holes opposite the cells; c) producing conductive inserts (28) in the holes and the cells; d) separating the insulating film (26) provided with conductive inserts.
