Abstract

PURPOSE:To find an abnormal pattern rapidly with high precision, by floating the open and short circuit part of the circuit pattern part of a printed writing substrate by using a mask plate. CONSTITUTION:A pattern part 1 drawn on a printed wiring substrate with etching resist ink is exposed out, and the other part is covered with a mask plate. This mask plate is provided with mark parts 6 and 7 for location alignment. Then, this mark plate is superposed on the substrate and then adjusted so that inspection mark parts 6 and 7 provided on the substrate are coincident with the mark parts 8 and 9. At this time, if there is an open part A in the pattern part, the open part A is seen floating. Further, when the mask plate is provided covering the pattern part while exposing the other part, the short circuit part of the pattern part is seen floating. Thus, the abnormality of the pattern is found rapidly with high precision.
