ABSTRACT:
A circuit fabrication device (10) is used to develop production or prototype circuits. A circuit board (16) having a conductive layer (26) provided thereon is placed in a plotter (14). An electrode (20) connected to a power supply (18) "draws" on the circuit board, thereby vaporizing piortions of the conductive layer patterned conductive regions (30) are thus formed on the conductive layer separated by isolation regions (28) where the portions of the conductive layer have been removed by vaporization in defining a circuit pattern on the conductive layer of the circuit board.
