Abstract

The invention relates to an electronic module comprising at least one electronic or electric component ( 3 ), a base plate ( 4 ), and a support plate ( 2 ), in particular a printed circuit board or a substrate. Said support plate ( 2 ) is arranged on the base plate ( 4 ) and comprises conductor paths. Said base plate ( 4 ) comprises a blind hole-type recess ( 5 ) on a side oriented towards the support plate ( 2 ). The component ( 3 ) is in contact on the support plate ( 2 ) and is arranged in the recess ( 5 ) of the base plate ( 4 ).

First claim

The invention claimed is:

1. An electronic module, comprising:
at least one electronic or electric component ( 3 ),
a base plate ( 4 ) and
a support plate ( 2 ), said support plate ( 2 ) being arranged on the base plate ( 4 ) and comprising conductor paths,
wherein said base plate ( 4 ) comprises a blind hole-type recess ( 5 ) on a side oriented towards the support plate ( 2 ),
wherein the at least one electronic or electric component ( 3 ) is mounted on the support plate ( 2 ) and is arranged in the recess ( 5 ) of the base plate ( 4 ), and
wherein the support plate ( 2 ) comprises a base area ( 20 ) and at least one connection element ( 21 ), which is integrally formed with the base area ( 20 ) and is positioned at a non-zero angle (α) to said base area ( 20 ), a sensor ( 6 ) being arranged in the at least one connection element ( 21 ).

2. The electronic module according to claim 1 , characterized in that at least one sensor ( 6 , 8 ) is arranged on a side of the support plate ( 2 ) facing away from the base plate ( 4 ).

3. The electronic module according to claim 1 , characterized in that the at least one electronic or electric component ( 3 ) is an interference suppression component.

4. The electronic module according to claim 3 , characterized in that the interference suppression component is arranged on the support plate ( 2 ) facing the base plate ( 4 ) in proximity of a component in which interference is to be suppressed.

5. The electronic module according to claim 1 , characterized in that the at least one electronic or electric component ( 3 ) is a HDI printed circuit board.

6. The electronic module according to claim 1 , characterized in that a cavity ( 5 a ) of the recess ( 5 ) is completely or partially filled with a sealing compound.

7. The electronic module according to claim 1 , characterized in that the base plate ( 4 ) is embodied as a cooling plate.

8. The electronic module according to claim 1 , characterized in that the at least one electronic or electric component ( 3 ) arranged in the recess ( 5 ) is fixedly bonded in said recess ( 5 ) by means of an adhesive.

9. The electronic module according to claim 1 , further comprising a reinforcing element ( 7 ) which supports the connection element ( 21 ).

10. The electronic module according to claim 1 , characterized in that the support plate ( 2 ) is a printed circuit board or a substrate.

11. The electronic module according to claim 1 , characterized in that the base plate ( 4 ) is embodied as a cooling plate made from aluminum.

12. The electronic module according to claim 1 , characterized in that a cavity ( 5 a ) of the recess ( 5 ) is completely or partially filled with a sealing compound which has a very good thermal conductivity.
