Metal-foil-clad composite ceramic board and process for the production thereof |
摘要 |
A metal-foil-clad composite ceramic board produced by impregnating by impregnating a sintered substrate (II) of an inorganic continuously porous sintered body (I) having a true porosity of 12 to 50% and an open porosity of at least 10%, with a thermosetting resin (R) under vacuum, to form a resin-impregnated sintered substrate (IIR), stacking a metal foil on the resin-impregnated sintered substrate (IIR) and press-forming the resultant laminate, wherein the stacked metal foil has a 10-point average surface roughness Rz of 10 mu m or less, and the resin-impregnated sintered substrate (IIR) and the metal foil have substantially no adhesive layer therebetween or have an adhesive layer having a thickness of 10 mu m or less therebetween.
