The detection circuit 3 is arranged in the open area of the outer layer of the PCB board body 1. The width of the detection circuit 3 is 10 mil. Test points are set at both ends of the detection circuit 3. After all the positions requiring beveled edges 2 in the beveled edge 2 program are completed, the beveled edge 2 is produced on the detection circuit 3. After the beveled edge 2, the detection circuit 3 is milled off. A test link is added during the post-process test. When the test result is an open circuit, the detection circuit 3 is milled off and the beveled edge 2 is not leaked. If the test result is a short circuit, the detection circuit 3 is not milled off, indicating that the PCB board body 1 leaks the beveled edge 2.
