Patent ID: 8355259

Claim:
A method for connection of an electronic module to a substrate, comprising: providing an electronic module; providing a substrate carrying electrical and/or optical circuits; connecting a connector electrical circuit between the substrate and the electronic module, wherein the connector electrical circuit is electrically demountable dry connected to the electronic module; wherein the connector electrical circuit comprises a flexible electrical circuit having a first compatible interface area for connection to the electronic module, the first compatible interface area including a first overgrown metal pad with noble metal finishing; wherein the electronic module includes a second compatible interface area for connection to the flexible electrical circuit, the second compatible interface area including a second metal pad with noble metal finishing metallurgical compatible with the finishing of the first overgrown metal pad; and wherein said connecting the connector electrical circuit between the substrate and the electronic module further includes demountable dry connecting the flexible electrical circuit to the electronic module, wherein the first and second overgrown metal pads self adjust one into the other based on applied vertical loading connecting electrically differing parts when in contact; wherein the first overgrown metal pad for the compatible interface is of different hardness than the second overgrown metal pad of the second compatible interface; and wherein said demountable dry connecting the flexible electrical circuit to the electronic module further includes self adjust penetrating the first and second overgrown metal pads one into the other, wherein the flexible electrical circuit is demountable dry connected to the electronic module, wherein when in contact the interface areas self adjust one into the other based on applied vertical loading connecting electrically differing parts of different hardness.
