METHOD FOR THE PRODUCTION OF A CIRCUIT BOARD INVOLVING THE REMOVAL OF A SUBREGION THEREOF, AND USE OF SUCH A METHOD

摘要

The invention relates to a method for producing a circuit board (1) involving the removal of a subregion (6) thereof. In said method, at least two layers or plies (2, 3, 4, 5) of the circuit board (1) are interconnected, the subregion (6) to be removed is prevented from being connected to an adjacent ply (4) of the circuit board (1) by providing or applying an adhesion-preventing material (7), and peripheral zones (8) of the subregion (6) to be removed are separated from adjoining zones of the circuit board (1). According to the invention, once the peripheral zones (8) have been separated or entirely cut off, an outer surface (9) of the subregion (6) to be removed is coupled or connected to an external element (11), and the subregion (6) to be removed is separated from the adjacent ply (4) of the circuit board (1) by lifting or displacing the external element (11), thus making it possible to remove a subregion (6) to be removed from a circuit board (1) in an easy and reliable, and if necessary automated, manner. Also disclosed is a use of such a method for producing a multilayer circuit board (1) and especially for creating voids (14) in such a circuit board (1).
