Abstract
A low thermal resistance insulating support permitting thermal stresses in the base of a high power component incorporating a beryllium oxide element without fractures or flaws occurring. The support includes a dissipating support made from copper, whose two large faces are slotted to at least partly house a beryllium oxide disk which receives a component and its connections to the outside. Such also completely houses a molybdenum disk with an expansion coefficient close to that of the beryllium oxide.
