Abstract:
A circuit board has a plurality of circuit board layers that are arranged one over the other, and that each include an electrically insulating base material having a glass transition temperature greater than or equal to 170° C. The circuit board layers each further have at least one thermally conductive layer applied to the base material. Several vias extend through respective ones of the circuit board layers to connect thermally conductive layers of different circuit board layers, such that the vias and the thermally conductive layers form a thermally conductive bridge from a topmost circuit board layer to a bottommost circuit board layer.
Abstract:
The invention relates to a control device assembly, in particular for a motor vehicle, comprising a printed circuit board that receives the control device electronics. At least one discretely formed frame element is supported on a populated face of the printed circuit board, enclosing at least one electronic component. A seal sits against an outer circumferential surface of the frame element, said seal surrounding the circumferential surface, and the seal is pressed against the printed circuit board by a housing element in order to form an electronic chamber that is sealed in a media-tight manner.
Abstract:
A control device has a base plate, a cover plate coupled to the base plate, a cavity formed between the base plate and the cover plate, a circuit carrier disposed in the cavity, and a conducting track carrier electrically coupled to the circuit carrier. The base plate has a continuous recess that is configured and arranged for feeding a casting compound into the cavity between the base plate and the cover plate. The casting compound is embodied to at least partly enclose the circuit carrier and/or the conducting track carrier in a vibration-damping manner.

Abstract:
A method for producing an electrical connection between a rigid printed circuit board and a metallic contact partner, includes preparing the rigid printed circuit board having at least one copper layer and at least one prepreg layer, bringing the metallic contact partner and the printed circuit board together in such a way that the metallic contact partner is brought into contact with a contact pad on the copper layer of the printed circuit board, forming a cutout in the printed circuit board by removing the prepreg layer in at least one partial region of the contact pad, and irradiating with laser light to form a weld connection between the contact partner and the contact pad. A configuration of a rigid printed circuit board, a metallic contact partner and an electrical connection point, as well as a module having such a configuration, are also provided.
