METHOD FOR DEFINED MECHANICAL DRILLING OF ELECTRIC PRINTED CIRCUIT BOARDS OR PRINTED CIRCUIT BOARD STACKS AND DRILLING SUPPORT FOR USE IN THIS METHOD

摘要

The invention relates to a method for defined mechanical drilling of electrical printed circuit boards or printed circuit board stacks. According to this method, an electrical signal for determining the final level of the drilling depth is obtained from the contact of the bit with a conductive layer (2). The method is characterised in that the conductive layer (2) concerned is part of a drilling support. In this way, the inventive method can be used for drilling through the printed circuit boards or printed circuit board stacks.
