Title:
DEVICE AND METHOD FOR MARKING CIRCUIT BOARD
Document Type and Number:
Japanese Patent JP2002033564
Kind Code:
A
Abstract:
To mark a printed circuit board without any error.
A fuse 4 is arranged at a visible position on the printed wiring board. An inspecting device outputs a marking indication signal 10 to a control circuit 11 when it becomes evident that the printed circuit board is normal by inspecting the printed circuit board. Consequently, the control circuit 11 supplies an electrification signal 6 to an electrifying circuit 8, which then supplies a sufficient current for the blowing of the fuse 3 to the fuse 4, so that the fuse 4 is blown. The printed circuit board is therefore inspected by viewing the state of the fuse 4 on the printed circuit board and it can be always accurately known whether or not the printed circuit board is normal.
