Claims

[Scope of utility model registration request]

In an apparatus for inspecting the dimensions of wiring patterns on both the front and back sides of a printed wiring board, a double-sided imaging means for simultaneously capturing images of both the front and back sides of the printed wiring board by holding CCD cameras at respective plane-symmetrical positions with respect to the printed wiring board; An image pattern matching means for pattern matching the images of the CCD camera of the stand pixel by pixel and evaluating the pattern matching status; A means for inspecting the matching state of the wiring patterns on both the front and back surfaces of the entire printed wiring board, and after inspecting the matching state of the wiring patterns on both the front and back sides of the entire printed wiring board by the above series of means, the position of the wiring pattern on the printed wiring board is determined. A wiring pattern storage stage that automatically determines and stores dimensional data regarding the shape;
Based on the data stored by the wiring pattern storage stage, the area to which the double-sided imaging means and the wiring pattern matching means are automatically sequentially applied is limited to the wiring pattern of the printed wiring board and its vicinity, and the printing A dimension inspection device equipped with a means for inspecting the matching status of wiring patterns on both the front and back sides of an entire printed wiring board having the same wiring pattern as the wiring board.
