ABSTRACT:
A method and a device for manufacturing multilayer ceramic capacitors, in which a plate of ceramic material composed of several layers is subdivided in the green non-sintered state into separate capacitor elements. For this purpose, by means of notching members, notches of a given depth are provided simultaneously on both sides of the plate in such a manner that spontaneous ruptures are obtained through the remaining thickness of the plate. Due to this method, the contamination of the exposed electrode layers and delamination are avoided. By the use of a frame with resilient walls, the already separated capacitor elements are held together until the notching process has been carried out completely.
