Title: Inspecting device for printed circuit board
Inventor: KATAOKA KENSEI
IPC: H05K3/34
Filed: 1988-11-02
Abstract: PURPOSE:To facilitate the inspection of condition of soldering at required points by performing a magnified projection at required points of a printed circuit board fixed on a moving table with a monitor camera. CONSTITUTION:A printed circuit board having electronic components mounted thereon is fixed on a moving table 40. Moreover, a motor is driven to move the moving table 40 by the operation of a moving switch 21. A magnified projection is performed on a monitor TV 63 with a monitor camera 61 at required points of the printed circuit board to facilitate an inspection. Here, the position of the moving table 40 is stored by depressing a memory switch 22 to store stop positions of the moving table 40 sequentially beforehand, which allows automatic operation with an automatic change-over switch 24 and a start switch 25. Information on the stop position and sequence can be stored into an IC card. Then, when any abnormal point is discovered, a mark is applied with a marking pen 67 using a stop switch 26 and a marking switch 27.
