Method for manufacturing a circuit board and a system of circuit boards as well as a circuit board and a system of circuit boards made by the methods

摘要

The method involves forming a groove-shaped opening (4) with lateral projections (7) in a printed circuit board in an area of contacting surfaces (11-14) for receiving a terminal strip of another printed circuit board. An inner side of the opening is coated with a conductive layer, so that an electrical connection is made with the surfaces. The opening is broadened, such that the layer is received in the projections. An independent claim is also included for a printed circuit board system comprising printed circuit boards.
