Abstract
Abstract An electric component comprising at least two flat elements is produced by coating a side of one of the elements, a metal sheet, with a co-polymer layer or by taking a sheet having a co-polymer layer thereon, and punching first elements therefrom. The co-polymer layer is softened by heating and the second element is pressed controllably onto the first and into the co-polymer layer. The layer does not run and so maintains an insulating separation between the elements, while bonding the elements firmly together. Piezoceramic resonators and semi-conductors circuits are advantageously joined to punch-formed parts in this manner.

87 words
A process for producing an electric component part having at least two elements joined to one another by an insulating copolymer layer, comprising: stamp-punching a first element from a metal sheet having an insulating copolymer on at least one side thereof; heating said first element with said copolymer layer thereon to a softening temperature of said copolymer; and pressing a second element onto the so-heated copolymer layer on the first element while substantially simultaneously embedding electrically-conductive wires connected to the second element into said heated copolymer layer.
