ABSTRACT:
Electrical conductor arrangement consists of a lamina of ceramic, such as alumina, which has copper foils bonded to both faces. The foils are of different thicknesses, and they are bonded at a high temperature, so that on cooling the ceramic lamina adopts a curved profile. By mounting the lamina with the convex surface mounted towards a heat sink, it can be clamped at its edges to ensure a good thermal contact over the whole of its surface.
