Abstract

A first and second substrate, and electrically conductive first and second connection parts are provided in a method for establishing an electrically conductive connection between two substrates. The first connection part is mounted on the first substrate by a first releasable connection and the second connection part is respectively mounted on the second substrate by a releasable connection. An electrically conductive connection assembly containing the first connection part and the second connection part is established by either a cohesive connection between a connection portion of the first connection part and a connection portion of the second connection part or an electrically conductive crossmember provided and a cohesive connection of a first length portion of the crossmember to the connection portion of the first connection part and a second cohesive connection of a second length portion of the crossmember to the connection portion of the second connection part being established.

First claim

The invention claimed is:

1. A method for establishing an electrically conductive connection between two substrates, comprising:
providing a first substrate and a second substrate,
providing an electrically conductive first connection part having a proximal end portion and a distal end portion,
mounting the first connection part on the first substrate by establishing a first releasable connection between a mounting portion of the first connection part at the proximal end portion of the first connection part and the first substrate via a through hole in the first substrate,
providing an electrically conductive second connection part having a proximal end portion and a distal end portion,
mounting the second connection part on the second substrate by establishing a second releasable connection between a mounting portion of the second connection part at the proximal end portion of the second connection part and the second substrate via a through hole in the second substrate,
and
producing an electrically conductive connection assembly which contains the first connection part and the second connection part,
wherein producing the connection assembly comprises:
either establishing a cohesive connection between a connection portion of the first connection part at the distal end portion of the first connection part and a connection portion of the second connection part at the distal end portion of the second connection part,
or providing an electrically conductive crossmember, establishing a cohesive connection of a first length portion of the crossmember with the connection portion of the first connection part at the distal end portion of the first connection part and establishing a second cohesive connection of a second length portion of the crossmember with the connection portion of the second connection part at the distal end portion of the second connection part.

2. The method as claimed in claim 1 , wherein a welded connection is established as at least one of the cohesive connection and the second cohesive connection.

3. The method as claimed in claim 2 , wherein
an electrically conductive first punched strip is provided as the first connection part and an electrically conductive second punched strip is provided as the second connection part,
the first substrate and the second substrate are mounted in a position fixed relative to one another in such a way that the connection portion of the first punched strip and the connection portion of the second punched strip overlap in an overlap region, and
the cohesive connection between the connection portion of the first connection part and the connection portion of the second connection part is established within the overlap region.

4. The method as claimed in claim 2 , wherein
an electrically conductive first platform is provided as the first connection part and an electrically conductive second platform is provided as the second connection part,
a crossmember is provided as the electrically conductive crossmember, the first length portion of said crossmember adjoining its first longitudinal end and the second length portion of said crossmember adjoining its second longitudinal end,
the first substrate and the second substrate are mounted in a position fixed relative to one another in such a way that the first length portion of the crossmember overlaps the connection portion of the first platform in a first overlap region and that the second length portion of the crossmember overlaps the connection portion of the second platform in a second overlap region, and
the cohesive connection between the first length portion and the first connection portion is established within the first overlap region and the second cohesive connection between the second length portion and the second connection portion is established within the second overlap portion.

5. The method as claimed in claim 1 , wherein
an electrically conductive first punched strip is provided as the first connection part and an electrically conductive second punched strip is provided as the second connection part,
the first substrate and the second substrate are mounted in a position fixed relative to one another in such a way that the connection portion of the first punched strip and the connection portion of the second punched strip overlap in an overlap region, and
the cohesive connection between the connection portion of the first connection part and the connection portion of the second connection part is established within the overlap region.

6. The method as claimed in claim 5 , wherein the connection portion of the first punched strip extends substantially parallel to a main plane of extent of the first substrate after the first releasable connection is established and before the cohesive connection is established and/or the connection portion of the second punched strip extends substantially parallel to a main plane of extent of the second substrate after the second releasable connection is established and before the cohesive connection is established, and a length portion of the first punched strip, which length portion adjoins the mounting portion, runs substantially at a right angle to the connection portion of said first punched strip and/or a length portion of the second punched strip, which length portion adjoins the mounting portion, runs substantially at a right angle to the connection portion of said second punched strip.

7. The method as claimed in claim 6 , wherein there is a gap between the connection portion of the first punched strip and the connection portion of the second punched strip transversely to a longitudinal direction of the connection portion of the first punched strip and/or transversely to a longitudinal direction of the connection portion of the second punched strip after the step of mounting the first substrate and the second substrate in a position fixed relative to one another, this gap being reduced or eliminated by elastically bending the first punched strip and/or the second punched strip, before the connection portion of the first punched strip is connected to the connection portion of the second punched strip by the cohesive connection.

8. The method as claimed in claim 5 , wherein there is a gap between the connection portion of the first punched strip and the connection portion of the second punched strip transversely to a longitudinal direction of the connection portion of the first punched strip and/or transversely to a longitudinal direction of the connection portion of the second punched strip after the step of mounting the first substrate and the second substrate in a position fixed relative to one another, this gap being reduced or eliminated by elastically bending the first punched strip and/or the second punched strip, before the connection portion of the first punched strip is connected to the connection portion of the second punched strip by the cohesive connection.

9. The method as claimed in claim 5 , wherein the step of mounting the first substrate and the second substrate in a position fixed relative to one another involves the first substrate and the second substrate being attached to a carrier which is jointly associated with them to either a technical device, a housing, or a heat sink, wherein at least one of the proximal end portion of the first connection part and the proximal end portion of the second connection part are partially disposed in a respective receiving part in the carrier.

10. The method as claimed in claim 1 , wherein
an electrically conductive first platform is provided as the first connection part and an electrically conductive second platform is provided as the second connection part,
a crossmember is provided as the electr
