<p>PURPOSE: To easily form a desired wiring pattern by inserting a jig having a burning insertion pin in the position corresponding to a through-hole provided in all intersections of a plurality of conductors disposed in parallel to the longitudinal and lateral directions on an insulating board to cut off a desired conductor by burning. CONSTITUTION: A through-hole 2 is provided in all the intersections of a plurality of wiring patterns 1 respectively provided in parallel to the longitudinal and lateral directions on an insulating board 8. Four electrified parts 3 connected to the respective wiring patterns 1 extending to the through-hole 2 from the vertical and horizontal directions are provided in the periphery of the through- hole 2. A burning insertion jig 4 has a number of burning insertion pins 6 which are planted in the plate-like base 9 and correspond to the through-hole of the board 8. The burning insertion pins 6 are inserted into all the through-holes 2, a current is supplied to the specified burning insertion pins 6 from a connector 5, and the wiring pattern 1 between two adjacent through-holes 2 is cut off by burning. Thereby, a new desired electronic circuit wiring pattern is easily formed.</p> |
