Patent ID: 7884287

Claim:
A connecting device for electrically conductively connecting electronic components and at least one substrate, wherein the connecting device comprises: a first electrically conductive film, said first electrically conductive film being formed of a first metal, and having a first thickness; a second electrically conductive film, said second electrically conductive film being formed of a second metal, and having a second thickness, said first and second thicknesses being not substantially the same; and a first insulating film disposed between said first and second electrically conductive films; said first and second electrically conductive films and said first insulating film together forming a film composite, said film composite having at least one embossing bump; wherein at least one of said first and second electrically conductive films is structured and thereby forms at least one conductor track; and wherein said at least one conductor track is soldered to said at least one embossing bump.
