Title: Jointing inspection device
Inventor: BABA YOICHIRO
IPC: H05K3/00
Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To remove the influence due to intensity distribution of X-ray irradiation, when determining a joint defect by imaging an X-ray radiographic image of a jointed article formed by the solder joint of electronic components. SOLUTION: For each pixel of the radiographic image (with determination range) acquired by irradiation of X-rays, the lightness difference between the pixel itself and the adjacent pixel is calculated, and when the lightness difference exceeds a prescribed threshold, the pixel is set to have maximum lightness (contour pixel extraction) (S108). Then, all pixels in a domain enclosed by the contour pixels are set (filled) to have the same maximum lightness as the contour pixels (S110). The number of pixels having the maximum lightness is measured, and defect in the joint is decided, based on the number of the pixels (S112, S114). The lightness difference between adjacent pixels on a contour part appears large in the case of a bubble defect, and the lightness difference between adjacent pixels, based on the X-ray intensity distribution, appears small. Therefore, the influence of the X-ray intensity distribution can be removed by setting a proper value as the prescribed threshold, to thereby decide the joint defects more accurately.
