NC Routing: – Individual boards are cut from manufacturing panel – Use NC Router, similar to NC Drilling equipment. When used in conjunction with the catalyst, a very constant etch rate can be maintained throughout the life of the bath. The Engineering office Friedrich has been developing layout and CAD software for PCB design and Application Oriented Special Integrated Circuits (ASICs) since 1989.
