Abstract

An electrical component includes at least one external contact having a first metallization and a second metallization. The metallizations are fired and the second metallization only partly covers the first metallization. Furthermore, an electrical component includes at least one frame-shaped metallization. Furthermore, an electrical component includes a first and second metallization that have a different wettability with solder material.

First claim

The invention claimed is:

1. An electrical component, comprising an external contact overlying a component body, the external contact having a first metallization and a second metallization, arranged on the first metallization, wherein the first and second metallizations are fired, wherein the second metallization only partly covers the first metallization, wherein the second metallization is U-shaped, wherein the U-shape has two legs and a connecting portion connecting the two legs, and wherein the legs and the connecting portion lie directly on the first metallization.

2. The electrical component according to claim 1 , wherein the first and second metallizations have a different wettability with solder material.

3. The electrical component according to claim 1 , wherein the first metallization has a glass portion and wherein the second metallization has no glass portion.

4. The electrical component according to claim 1 , wherein the first metallization has a glass portion and wherein the second metallization has a smaller glass portion than the first metallization.

5. The electrical component according to claim 1 , wherein the second metallization has at least one cutout.

6. The electrical component according to claim 1 , wherein the first metallization is embodied as a continuous area without any cutouts.

7. The electrical component according to claim 1 , wherein the second metallization has at least one cutout.

8. The electrical component according to claim 1 , further comprising a contact element soldered on the second metallization.

9. The electrical component according to claim 8 , wherein the contact element has a fabric structure.

10. The electrical component according to claim 8 , further comprising a contact-connection fixed to the contact element, wherein the contact-connection is not arranged above the second metallization.

11. The electrical component according to claim 10 , wherein the contact-connection is embodied as a contact pin.

12. An electrical component, comprising an external contact having a first metallization and a second metallization arranged on the first metallization, wherein the first and second metallizations are fired, wherein the second metallization has a cut-out, wherein the first metallization is present beneath the cut-out, and wherein the first metallization has a smaller wettability with solder material than the second metallization.

13. A method for establishing electrical contact with an electrical component, the method comprising:
providing a main body of an electrical component;
applying a first metallic paste on an outer side of the main body;
firing the first metallic paste to form a first metallization;
applying a second metallic paste to the first metallization; and
firing the second metallic paste to form a second metallization.

14. The method according to claim 13 , wherein the second metallization is formed so as to only partly cover the first metallization.

15. The method according to claim 13 , wherein the second metallization is formed in a U-shaped fashion.

16. The method according to claim 13 , wherein the first metallization has a glass portion and wherein the second metallization has no glass portion or a smaller glass portion than the first metallization.
