ABSTRACT:
A unique general-purpose circuit board and a unique burning jig implement a wiring pattern for the trial manufacture of a new electronic circuit. The circuit board is implemented as an insulative plate on which horizontal and vertical parallel conductive lines are provided, and in which through holes are formed at the junctions of the lines. Each through hole is surrounded by four conductive portions insulated from each other and each being connected to a particular conductive line. The burning jig has a flat base and burning pins studded on the base and each corresponding to one of the through holes. Each burning pin has four metal pieces at one end thereof. The four metal pieces are insulated from each other and respectively correspond to the four conductive portions surrounding a single through hole. After the pins of the jig have been inserted into the through holes of the circuit board, the line connecting any nearby through holes is burned off by a current fed to between the metal pieces of the corresponding pins.
