wherein the electronic component ( 3 ) is supported by the press-in domes ( 75 ) of the seal carrier ( 71 ) to absorb a press-on force ( 4 ) when the printed circuit board ( 5 ) is pressed onto the pins ( 30 ).

2. The electronic arrangement as claimed in claim 1 , further comprising a holding plate ( 8 ), which is connected to the base plate ( 2 ) and which pre-tensions the electronic component ( 3 ) in a direction of the base plate ( 2 ).

3. The electronic arrangement as claimed in claim 2 , wherein the holding plate ( 8 ) is arranged on a side of a sub-region ( 35 ) of the electronic component ( 3 ) which is opposite the base plate ( 2 ), and wherein the base plate ( 2 ) has at least one contact device ( 20 ), which protrudes parallel to the press-in access ( 4 ) and against which the holding plate ( 8 ) abuts.

4. The electronic arrangement as claimed in claim 2 , wherein the press-in domes ( 75 ) are configured such that a sum of a first restoring force of all press-in domes ( 75 ) and a second restoring force of the seal ( 72 ) is greater than or equal to the predetermined press-on force ( 40 ) with which the printed circuit board ( 3 ) is pressed onto the pins ( 30 ).

5. The electronic arrangement as claimed in claim 1 , wherein the seal carrier ( 71 ) and the seal ( 72 ) surround the cooling region ( 6 ) in a ring-like manner.

6. The electronic arrangement as claimed in claim 1 , wherein the seal arrangement ( 7 ) has first and second seals ( 72 , 73 ), wherein the first seal ( 72 ) is arranged between the seal carrier ( 71 ) and the electronic component ( 3 ), and wherein the second seal ( 73 ) is arranged between the seal carrier ( 71 ) and the base plate ( 2 ).

7. The electronic arrangement as claimed in claim 1 , wherein a plurality of the press-in domes ( 75 ) in each case are grouped together to form press-in dome groups ( 70 ), and wherein multiple press-in dome groups ( 70 ) are arranged distributed around a circumference of the seal carrier ( 71 ).

8. The electronic arrangement as claimed in claim 7 , wherein each press-in dome group ( 70 ) has at least two press-in domes ( 75 ), and wherein the seal carrier ( 71 ) has at least four press-in dome groups ( 70 ).

9. The electronic arrangement as claimed in claim 1 , wherein each press-in dome ( 75 ) has, in a cross-sectional plane perpendicular to the press-in axis ( 4 ), a length to width ratio of at least one.

10. The electronic arrangement as claimed in claim 1 , wherein the seal carrier ( 71 ) is made of plastic material.

11. The electronic arrangement as claimed in claim 1 , wherein the press-in domes ( 75 ) are arranged facing the electronic component ( 3 ) on the seal carrier ( 71 ).

12. A control unit, comprising an electronic arrangement ( 1 ) as claimed in claim 1 .

13. A method for assembling an electronic arrangement ( 1 ), comprising the steps:

providing a seal arrangement ( 7 ) having a seal carrier ( 71 ) and at least one seal ( 72 ),

arranging the seal arrangement ( 7 ) on a base plate ( 2 ),

arranging an electronic component ( 3 ) on a side of the seal arrangement ( 7 ) which is opposite the base plate ( 2 ),

pressing a printed circuit board ( 5 ) onto a plurality of pins ( 30 ) of the electronic component ( 3 ) along a press-in axis ( 4 ),

wherein the seal carrier ( 71 ) has a plurality of press-in domes ( 75 ) protruding parallel to the press-in axis ( 4 ), and

wherein the press-in domes ( 75 ) support the electronic component ( 3 ) during the pressing-on of the printed circuit board ( 5 ) in order to absorb a press-on force ( 40 ).

14. The method as claimed in claim 13 , further comprising the steps, prior to the pressing-on of the printed circuit board ( 5 ):

arranging a holding plate ( 8 ) on a side of a sub-region ( 35 ) of the electronic component ( 3 ) which is opposite the seal carrier ( 71 ), and

pre-tensioning the electronic component ( 3 ) against the base plate ( 2 ) by means of the holding plate ( 8 ).

15. The method as claimed in claim 14 , wherein the electronic component ( 3 ) is pre-tensioned against the base plate ( 2 ) by means of the holding plate ( 8 ) in such a way that the press-in domes ( 75 ) of the seal carrier ( 71 ) are deformed.

16. The electronic arrangement as claimed in claim 7 , wherein each press-in dome group ( 70 ) has maximally ten press-in domes ( 75 ), and wherein the seal carrier ( 71 ) has maximally twelve press-in dome groups ( 70 ).
