TLDR
In this paper, an ink-jet unit is connected with a personal computer and an insulator is placed on a carrier which can carry the insulator in the direction of travel by a jet of ink from a nozzle on the basis of pictorial information data transmitted by the computer.Abstract:
PROBLEM TO BE SOLVED: To enable manufacturing with cost reduction, without need for long time using a simple manufacturing method, by simultaneously forming a conductor pattern on the surface of an insulator. SOLUTION: An ink-jet unit 7 connected with a personal computer 10 has an ink-jet nozzle 8 which can be slid sideways and longitudinally, and an insulator 9 is placed on a carrier which can carry the insulator 9 in the direction of travel, and both of a conductor pattern and an insulating pattern are formed simultaneously on the surface of the insulator 9 by a jet of ink from a nozzle on the basis of pictorial information data transmitted by the personal computer. When ink to be used is solvent type or heat curing type, the insulator 9 is carried through a heating furnace subsequent to the ink-jet unit 7 for drying solvent or cure binder. This allows manufacturing time to be shorten by simple equipment and method.read more
