ABSTRACT:
The invention relates to a printed circuit board disposed on a film serving as the carrier material. A connector strip having a large number of connection pins is disposed on the printed circuit board using surface-mounting technology. Connector strips of this type are widespread in digital technology. In the case of circuits in the fields of power electronics or motor vehicle electronics, connector strips cannot be surface-mounted because of the larger cross-sections of the connections. In a printed circuit board of the type mentioned at the outset, recesses are provided in the film stiffener underneath the solder points, such that when the connection pins of the connector strip are soldered, level differences in the connection pins are compensated by the deformation of the carrier film. With this measure, tensions are compensated for the most part by the deformation of the carrier film, so that connector strips for power electronics and motor vehicle electronics applications can also be surface-mounted.
