Title: Pattern inspection for printed circuit board
Inventor: KITAKADO RYUJI
IPC: G06T7/00
Filed: 1991-05-31
Abstract: PURPOSE:To inspect a neck breakage of a wire pattern of a printed circuit board. CONSTITUTION:A wire pattern is read out optically to obtain a pattern image PI as binary coded image. An operator having a plurality of trains of arms is made to act on the pattern image to be separated into a land image RI corresponding to a land and a line image LI corresponding to a line. On the other hand, a hole image HI as binary coded image of a hole is obtained too. Whether a neck breakage occurs or not is judged by whether a residual value of the land image RI to be generated in the hole image HI is ensured above a threshold alpha or not. A magnification processing of the hole image HI is performed to obtain an overlapped part QI of an magnified hole image EI and a line image. The larger threshold alpha requires a larger magnification processing. The degree of the magnification processing can be determined with a due consideration given to quantization errors or the like. Thus, a neck breakage can be determined when the size of the overlapped part exceeds a certain degree.
