Method for producing a radio-frequency device maintaining anisotropic connection

The invention relates to a method for producing an intermediate device comprising an electronic module, said intermediate device being used to receive at least one film or portion of a film or covering layer, said device comprising: a supporting body; at least one area for the interconnection of an electric circuit, borne by the supporting body; and an electronic module connected to said interconnection area by an anisotropic connection material, said material being compressed between said area and the module. The method comprises the implementation of a means for maintaining the compressed state of said anisotropic material and/or a means for isolating said material from the outside of the supporting body.
