FIELD: instrument making.
SUBSTANCE: picture that represents a set of rectangles separated with isolating tracks is created in metal-ceramic housing of multichip semiconductor device on metal coating of reverse side of ceramic base. The shape of rectangles corresponds to projection of crystals brazed on mounting platforms of face side, and their dimensions coincide with enlarged effective cross-section of heat flow, the surface area of which exceeds surface area of crystal by thickness of ceramic base.
EFFECT: improving reliability of microwave transistors during their assembly and operation due to reducing inner stresses appearing in the brazed seam between ceramic base and flange when housings are being brazed.
