Abstract
An electronics unit includes a low multi-point metallic mount on which an insulating layer is arranged. A conductor track system is arranged on the insulating layer and electronic power components are arranged on the conductor track system. The insulating layer is a sintered electrically insulating polymer layer on which the conductor track system, which comprises a sintered glass frit with a noble metal filling, is arranged.
Claims12
An electronics unit, comprising:
- a low multi-point metallic mount comprising a material having a melting point below 600 degrees Celsius;
- an insulating layer comprising a sintered electrically insulating polymer layer arranged on said mount;
- a conductor track system comprising a sintered glass frit with a noble metal filling arranged on said insulating layer, the sintered glass frit having a melting point that is lower than the melting point of the metallic mount, so that the glass frit is sinterable onto said mount;
- a resistance layer printed onto the polymer layer within one area of the conductor track system;
- and
- electronic power components arranged on said conductor track system.
