Title: Substrate inspection device and substrate inspection method
Inventor: YAMASHITA MUNEHIRO
IPC: G01R31/02
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To inspect a substrate in a short time with a universal type inspection device. SOLUTION: To a switch part SW1, a constant voltage E is given from a signal source 46. A computer 44 turns on a switch part SW2 and then turns on the SW1. By this, an equivalent circuit closes, a current (i) flows and an input voltage Vx to an amplifier 74 is caused. The voltage Vx is amplified by the amplifier 74 and the maximum value is detected and held by a peak hold circuit 76. Based on the maximum value, the computer 44 judges the conduction state of the printed pattern of a substrate 32. The input voltage Vx to the amplifier 74 shows a maximum voltage at the same time the switch part SW1 is almost turned on. Therefore, the maximum value detection process can be finished in a very short time. And the judging process of the conduction state of the printed pattern can be done in a very short time.
