    • In order to inspect a board, a measurement area is set on a board, and reference data and measurement data of the measurement area are acquired. Then, a conversion condition is established for the measurement area, and a conversion relation is acquired according to a distortion degree between reference data and measurement data. Thereafter, validity of the conversion relation is verified by using at least one of verifying that a comparison feature object satisfies the conversion relation, verifying that a verification feature object selected from feature objects satisfies the conversion relation and verifying that a pad formed on the board satisfies the conversion relation. Then, the conversion condition is confirmed, and an inspection area for inspecting a measurement target is set according to the confirmed conversion condition. Thus, an inspection area may be correctly set so that distortion is compensated for.
    • 为了检查电路板,在电路板上设置测量区域,并且获取测量区域的参考数据和测量数据。 然后,对于测量区域建立转换条件,并且根据参考数据和测量数据之间的失真度获取转换关系。 此后,通过使用验证比较特征对象满足转换关系中的至少一个来验证转换关系的有效性,验证从特征对象中选择的验证特征对象是否满足转换关系,并且验证板上形成的垫是否满足 转换关系。 然后,确认转换条件,根据确认的转换条件设定检查对象的检查区域。 因此,可以正确地设置检查区域,从而补偿失真。
