Definitions
- the invention relates to a component with a ceramic body which is covered in at least a region on its surface with a metallization.
- the insulation and partial discharge resistance depends, among other things, on the thickness, material and homogeneity of the floor insulation, the housing and filling material and possibly also the chip arrangement.
- a plate-shaped metal-ceramic substrate which reliably maintains a partial discharge strength of ⁇ 10 pC.
- the object of the invention is to present a component with a metallized on its surface ceramic body, which is not exclusively plate-shaped, flat, and has a high partial discharge resistance.
- the object is achieved by means of the characterizing features of claim 1.
- Advantageous embodiments of the invention are presented in the dependent claims.
- the component according to the invention is spatially structured.
- the ceramic body is a three-dimensional structure.
- connect to a plate more parts so that a body arises in any form.
- the whole body is in one piece, d. h., he is not composed of individual parts.
- further plates are vertical on a plate, then for example an overall body can be produced which is E-shaped.
- Such a form for example, heatsinks.
- This partial discharge strength is achieved, depending on the predetermined same or different measuring method with the same or unequal or changing predetermined measuring voltage or the same or unequal or changing measuring conditions.
- Measurement conditions can be, for example, pressure or temperature or air humidity or equal or unequal distances of the metallizations.
- these defects may only have an edge profile, whose radius of curvature does not fall below 10 microns, so that the required partial discharge resistance of ⁇ 20 pC is not exceeded.
- a metallization metals are preferred in the form of coatings or films or sheets cohesively or by mechanical positive connection over the entire surface or part of the surface connected to the ceramic body, which have the same or different thermal conductivity as the ceramic body.
- the metallization can consist, for example, of tungsten, silver, gold, copper, platinum, palladium, nickel, aluminum or steel in pure or industrial quality or of mixtures of at least two different metals.
- the metallization can also, for example, additionally or alone, from reaction solders, soft solders or brazing alloys.
- the metals of the metallization in the form of coatings or foils or sheets may be added to adhesion promoting or other additives such as glasses or polymeric materials or they may be coated with it to increase the adhesion of the metallization on the ceramic body.
- the layer (s) of metallization are formed using a DCB (Direct Copper Bonding) or AMB (Active Metal Brazing) or screen printing or electrolytic or chemical deposition or vapor deposition process or by adhesion or bonding or a combination of these processes applied to the surface of the body on opposite and / or adjacent surfaces.
- the metallization on the ceramic body consists of at least one layer per metallized surface.
- the metallization covers the surface of the ceramic body as a metal body over part of the surface or over the entire surface or partially or completely in a plane-parallel or nearly plane-parallel shape or any geometrically shaped or in a combination of the forms.

- the connection with the ceramic body takes place by means of the screen printing process with subsequent thermal treatment or by means of the AMB process.
- an intermediate layer for the adhesion promotion has preferably a thickness of ⁇ 20 microns. If, for example, a metallization of copper is to be applied to an aluminum nitride ceramic by means of the DCB method, it is advantageous if an intermediate layer of Al 2 O 3 is produced on the surface of the ceramic body. This increases the adhesive strength of the metallization with copper.
- connection of the at least one metallization and / or a further metallization to the ceramic body is> 90%.
- the at least one metallization is connected to the ceramic body with an adhesive strength of at least 12 N / cm. This ensures that, in particular due to the thermal stress, no detachment of the metallization from the ceramic body takes place.
