Abstract
Monolithic ceramic capacitors are made by repeatedly passing a substrate through a falling sheet of a green-ceramic slurry, heating the substrate to dry each slurry coating before the next, on at least one dried coating screen printing a matrix of electroding-ink-film pairs and on an adjacent dried coating screen printing a matrix of electroding-ink-film patches. Each of the patches are registered over one pair of the films to form an area of overlap with one film of the one pair that is greater than the area of overlap formed with the other film of the one pair. A relatively large change in the adjustment of this registration advantageously produces a small change in the overall capacitance of the finished capacitor as measured between each pair of buried film electrodes. The final steps in the method include dicing the green-ceramic cake into bodies of rectangular profile, firing the bodies to maturity and applying conductive terminals to the body ends for contacting the films of the pairs.
