Abstract:
1. A method of using image taking means for inspecting a plurality of target portions on a substrate larger than the field of vision of said image taking means and having components mounted thereon by using images taken of said substrate a plural number of times by said image taking means, said method comprising inspection steps for an inspection and preparation steps carried out prior to said inspection steps, said inspection steps and preparation steps are performed using a computer, said preparation steps including: step A of setting a plurality of target areas according to the field of vision of said image taking means on a standard substrate of a standard substrate considered to be of acceptable quality such that mutually adjacent ones of said target areas have an overlapping portion by a specified amount and taking individual images of said target areas; step B of creating a whole image of said standard substrate by combining the images obtained in said step A; step C of specifying the image in each area in said whole image created in said step B as standard image in corresponding target areas at a time of the inspection; step D of specifying position and size of inspection area suitable to the standard image specified in said step C based on substrate design data corresponding to said standard substrate and setting the specified data as set data of said inspection area; and step E of registering said standard image specified in said step C and the set data of the inspection area specified in said step D for each the target areas at the time of said inspection; said inspection steps including:
