Document Type and Number:
WIPO Patent Application WO/2023/042440
Kind Code:
A1
Abstract:
Provided are a board testing apparatus and the like that enable improvement of yield and appropriate detection of foreign matter which can cause a functional problem on a printed board. In testing a printed board 1, an image is acquired first. The image includes a component mounting area Ma corresponding to a mounting position of a component with respect to the printed board 1, and covers an area that is to be tested in the printed board 1 and that is larger than the component mounting area Ma. Then, any foreign matter X in the area to be tested is detected on the basis of the acquired image. Further, without immediately determining that the detected foreign matter X is an imperfection, determination as to whether or not the foreign matter is an imperfection is made on the basis of the position relationship of the foreign matter X with respect to the component mounting area Ma. Therefore, even if foreign matter X has been detected, in a case where the foreign matter X cannot be considered to generate a functional problem of the printed board 1 judging from the position relationship with respect to the component mounting area Ma, it is possible to ensure that the foreign matter X is not determined to be an imperfection.
