Title: Through-hole inspecting apparatus
Inventor: ANDOU MORITOSHI
IPC: G01N21/956
Filed: 1983-01-28
Abstract: PURPOSE:To detect the void or the defect of the inner wall of the through-hole provided in a printed board, by illuminating the printed board by an illumination means provided with a light blocking means to the opening part of the through-hole. CONSTITUTION:A printed board 11 is illuminated by a fluorescent lamp 15 to which black rubber 12 is attached as a light blocking means for covering one opening end of a through-hole 16. Light 13a permeates the printed board 11 and a part thereof detected as leaked light 13b from the void or defect of the conductive layer 16a for constituting the inner wall of the through-hole 16 through a lens 14 by CCD15. Because the light blocking means is preliminarily attached to the illumination means, a holder is simplified and mutual positional adjustment becomes unnecessary. In addition, because the elongated illumination means can be used, a large number of the through-holes over a wide area can be detected at a constant position.
