The Circuit-Fix system has been designed to allow you to cut accurate, burrfree copper foil traces for PC boards for the purpose of adding to or repairing a circuit board.
Circuit-Fix is a handy system whether for prototype modifications or for circuit repairs. The system centers on a spring-loaded clamp & cutting guide that permits excellent trace cutting with a modeling knife. Both the knife & a sheet of self adhesive copper trace material are incl. Also included is a sheet of (assorted sizes) pure copper self-adhesive donut pads. The cut trace & donuts are burnished to the board & then soldered to component leads.
