The use of a control module having at least one housing part and a multi-layer printed circuit board as the electrical connection between the inner space of the housing and components that are situated outside of the housing part is described. The multi-layer printed circuit board is the carrier for the electrical components of an electronic circuit, and is at the same time the thermal contacting to a housing part and/or a cooling element, particularly a hydraulic plate of the transmission, for a transmission control installed in an automatic transmission.

The invention relates to a solderless electrical connection () between a first joining partner () and a second joining partner () for connecting an electrical component, a connector strip or a lead frame. According to the invention, the first joining partner () or both joining partners () have an OSP coating () on their respective contact surfaces ().

An electrical control unit has a printed circuit board substrate, on which an electronic circuit is situated, which circuit includes multiple electrical components which are interconnected via printed conductors of the printed circuit board substrate, as well as housing parts for covering the electrical components on the printed circuit board substrate, and at least one device plug connector part situated on the printed circuit board substrate outside the section of the printed circuit board substrate covered by the housing parts. Outside the section covered by the at least one housing part and outside the section of the printed circuit board substrate provided with the device plug connector part, at least one contact point for an additional electrical component is situated on the printed circuit board substrate.

An electrical circuit unit, particularly for motor vehicles, features a grounded housing (1) and a printed circuit board (2) which, for protection against incoming and outgoing radiation of electrical noise, is short-circuited at high frequencies to the grounded housing. For this purpose, a noise suppression capacitor (6) on the PC board (2) is connected in series to a second capacitor. This second capacitor is formed by a metallized surface (8) on the board (2) and a metal-filled adhesive, as a first plate, a metal inner surface (11) of the housing (1) as a second plate, and an intermediate passivation or eloxal layer serving as a dielectric (13). The metal-filled adhesive acts to electrically bridge most of the gap between the metallized surface (8) and the housing surface (11), thereby capacitively coupling the metal-filled adhesive to the housing (1) and increasing the capacitance.
