Abstract
A method of producing microbore holes in a multi-layer substrate ( ), preferably a printed circuit board substrate, that is displaced below writing optics ( ) by an XY stage ( ), using the optics to generate a spot from a light source ( ), preferably a laser. The method reduces the treatment time and preferably compensates for distortions in the substrate material. To this end, the position of the spot within a working field is changed simultaneously with the treatment positions by electronically controlled, movable mirrors. The position of the substrate is determined by an interferometer ( ), and the signals corresponding to the substrate position are processed by a suitable computer system ( ) to obtain an actual position of the table system. The computer system ( ) is preferably provided with all bore hole coordinates and additional information such as bore hole diameter, especially in tabular form.
