Assembly and production of an assembly
An assembly having a substrate and at least one component fastened thereon by sintering using a sintering agent, in particular sintering paste. The sintering agent is situated in a recess of the substrate that accommodates at least some areas of the component. A method for producing an assembly having a substrate and at least one component fastened thereon by sintering using a sintering agent, in particular sintering paste. The sintering agent is brought into a recess of the substrate that accommodates at least some areas of the component.
1. An assembly comprising:
a substrate;
at least one component;
a first metallic strip conductor affixed to a first side of the substrate and having a recess with (i) an uniquely contoured outline corresponding to a contour of the at least one component such that the at least one component has a single orientation in the recess in which the at least one component cannot be shifted and (ii) a depth that accommodates at least some areas of the at least one component; and
a second metallic strip conductor affixed to a second side of the substrate opposite the first side;
wherein the at least one component is fastened on the first metallic strip conductor in the recess by sintering using a sintering agent, the sintering agent and the at least one component being situated in the recess.
2. The assembly according to claim 1 , wherein the sintering agent includes sintering paste.
3. The assembly according to claim 1 , wherein the recess has an outline that corresponds substantially to a contour of the component.
4. The assembly according to claim 1 , wherein the sintering agent is a silver sintering paste or a solid sintering agent.
5. The assembly according to claim 1 , wherein the component is an electrical/electronic component, including a power semiconductor.
6. The assembly according to claim 1 , wherein the substrate is a pressed screen or a circuit board.
7. The assembly of claim 1 , wherein the recess of the substrate has at least one bulge at a corner of the recess containing an excess of the sintering agent situated in the recess.
8. The assembly of claim 7 , wherein the recess of the substrate has a bulge at each corner of the recess containing the excess sintering agent.
