## Abstract

A device including a conductor track foil with contact pins of an electrical component. The conductor track foil includes two insulating layers with an intervening conducting layer with lands in the upper layer for soldering the conductive layer to the contact pins of the electrical component. The conductor track foil is lowered, positionally correctly, onto the electrical component by use of a mounting device. The bottom insulating layer and the conducting layer of the soldering lands, which are free of an insulating layer on the top, are pierced by the contact pins extending at right angles to the conductor track foil. The conductor track foil is released by the mounting apparatus. A soldered connection is made between the lands and the contact pins. As a result, a device including an electrically reliably gap free conducting connection is attained even if the contact pins are eccentrically associated with the soldering lands.

## Claims

### Claim 1

An electrical device (10) comprising:
at least one electrical component (12), said electrical component (12) includes a plurality of aligned electrically conductive contact pins (14) extending therefrom,
a conductor track foil (18), said conductor track foil includes a lower insulator layer (19), an upper insulator layer (20) and a conductor layer (21) sandwiched between said lower and upper layers, said upper layer including aligned soldering lands (23) that extend to said conductive layer,
said bottom insulator layer and said conductive track (18) are pierced by said electrically conductive contact pins (14) in the area of said soldering lands (23) so that an electrical contact connection is formed between the electrically conductive contact pins (14) and the conductive layer in a gap-free manner and said electrically conductive contact pins are soldered to said conductive layer in the area of said soldering lands.

### Claim 2 (depends on 1)

A device as defined by claim 1, in which the contact pins are sharpened on their ends with a cut extending obliquely to their longitudinal axis to assist in piercing said lower insulator layer and said conductive layer in the area of said soldering lands (23).
