Abstract
Abstract A metal support element having electronic components or circuit supports, in particular hybrid circuits, the connections of which are guided through from the component side, via a plurality of connector pins melted into glass passthroughs, to the opposite side of the support element. The connector pins are glass-mounted into pin blocks produced independently of the support element. The pin blocks are inserted into associated cutouts of the support element and fastened therein. The arrangement and number of the connector pins in the pin blocks can thereby be flexibly adapted to particular requirements with no need for modifications to the design of the support element. The material and the geometrical properties of the pin blocks can be optimally adapted to the glass-mounting process of the connector pins, while the material of the support element can be matched to the coefficient of thermal expansion of the attached circuit support.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
A metal support element having a first side, a second side opposite the first side and a cutout, the metal support element comprising: at least one pin block gas-tight mounted and one of welded, adhesively bonded and soldered within the cutout, the at least one pin block having a plurality of passthroughs extending from the first side to the second side, the at least one pin block composed of Kovar; a plurality of connector pins for guiding through connections from the first side to the second side, each of the connector pins being sealed within a glass filling within a corresponding one of the passthroughs, the connections being associated with at least one of electronic components and circuit supports mounted on the first side, the at least one of the electronic components and the circuit supports including hybrid circuits; and a cap composed of a metal material and covering the at least one of the electronic components and the circuit supports on the first side, the cap being gas-tight mounted to a peripheral attachment region of the support element for encapsulating, in a hermetically-sealed manner, the at least one of the electronic components and the circuit supports under the cap.
