ABSTRACT:
The process for wiring substrates with a universal pattern of conductors and a large number of predetermined bonding/cutting localities is characterized in that from the quantity of all the possibilities for bonding and cutting is removed the quantity necessary for the realization of a given application, after realization of one given circuit this quantity is tested for further possibilities for realizing the circuit, and the found quantity of possibilities is made available as a correction quantity. The advantage of such a correction potential is that layout or contacting errors can be corrected in a second passage, so that wastage is reduced.
