Definitions
- the carrier plate according to the invention has the advantage that a very good thermal connection of components or the substrate surface of a micro hybrid circuit is possible.
- the carrier plate is characterized by high thermal conductivity and a low coefficient of thermal expansion. Because of the relatively small difference between the thermal expansion coefficients of the micro hybrid circuit or carrier plate, both can be coated with a very thin adhesive layer and without great tension. be connected to each other. It is no longer necessary to use special heat-conducting substances.
- FIG. 1 shows a section through a unit 1 according to the invention with a carrier plate 2 according to the invention in the form of an MMC heat sink and an electronic component 6.
- the carrier plate 2 consists of a ceramic body 3 made of Al-Si cermet. It is a porous SiC ceramic, the cavities of which are infiltrated with aluminum. The manufacturing process is known per se; these materials can be obtained from Alcoa or Lanxide, for example. Depending on the application, the ceramic body 3 is approximately 0.3 to 2 mm thick.
