Multiple layer ceramic substrate for electronic circuit

摘要

The substrate is of a large surface, insulating base layer (1) upon which is formed several individual substrates (3) for electric circuits, defined by rated break lines (18-20). Each consists of a base layer partial portion (4) and at least one metallising (6,8) on the partial portion surface. There are stabilising regions (14,15) against inadvertent breaking. The base layer has numerous apertures (2), whose edges form each at least one edge line of the partial portion of each individual substrate. At least one metallising (6) of each substrate protrudes beyond the edge into the aperture.
