PURPOSE:To sense shortcircuit between a cancel loop circuit and an FG circuit on a printed circuit board for motor during the manufacturing processes. CONSTITUTION:A cancel loop circuit 2 and an FG circuit 3 are formed in the condition out of continuity so that their termins are in connection with lands 6, 7 and ones 8, 9. The circuits 2, 3 in the condition out of continuity are subjected to a current application test to check if there is any shortcircuit between them. After this inspection, the lands 7, 9 on one side of the circuits 2, 3 are connected to put the circuit 2 in continuity to the one 3, and thereby a coil circuit is accomplished. |
