METHODS AND APPARATUS FOR MAKING SCRIBED CIRCUIT BOARDS

摘要

Improved methods and apparatus for making scribed circuit boards. A conductor is fed to the adhesively activatable surface of a board base which is attached to a movable table. The conductor is affixed to the adhesive surface by means of an energizeable stylus, the energization of the stylus being modulated proportional to the velocity of the table. The feed of the conductor and the movement of the base are monitored and compared and a control signal produced if the conductor feed and base movement are not in substantial agreement. The conductor is positively fed to the board base to eliminate pull on the conductor and substantially reduce the tendency of the conductor to come loose from the board base. The forming stylus has a vertical groove on at least one side which becomes progressively shallower towards the bottom and which has side walls for laterally confining the conductor.
