ABSTRACT:
To permit easy attachment, for example, by soldering, of a connecting lead wire to a conductive track on a ceramic plate connected closely adjacent to another plate which may also be ceramic, the first ceramic plate, at least, is bent away from the other ceramic plate at the connecting portion during manufacture; the manufacturing process includes heating the plate to be bent away to be in plastic condition and then applying a bending force to form the bend, permitting the so bent plate to cool, and joining the so-bent plate to the other plate with which it is to form a composite, for example, by glass melt. The bending force may be gravity, by permitting the unsintered plate, upon heating, to fall on a curved surface; or the bending force can be generated by applying a layer of a material having differential shrinkage to the flat, unsintered plate, and heating the composite, so that, upon differential shrinkage, the ceramic plate will be bent away from its originally plane, flat state.
