している。第10図はその代表的な例を示している。(Prior Art) Generally, in a printed wiring board, through holes are formed in order to electrically connect respective conductor circuits formed on both front and back surfaces thereof, for example. To form a through hole for conduction in such a printed wiring board, a hole is made in the board by punching or drilling, then this board is dipped in the plating pretreatment layer and the plating layer, and the inner wall of the hole is plated. Has been given. Figure 10 shows a typical example.

ある。Figure 10 shows the substrate (19) in the plating tank (21).
Is supported at its upper end, and in this state, the substrate (19) is swung in the direction of drilling the through hole (20). The swing of the substrate (19) itself attempts to obtain a liquid flow in the through hole (20).
Since 9) is swung while being supported by its upper end, as shown by the arrow in FIG. 10, this substrate (1
In the case of 9), a swing difference occurs in which a portion near the bottom of the processing tank (21) is swung smaller than a portion near the liquid surface. Therefore, the position of the through hole (20) provided on the substrate (19) causes a difference in the liquid flow generated therein, and the plating thickness for the through hole (20) varies depending on the location, and uniform plating is performed. There is a phenomenon such as not.

The aspect ratio of the substrate (19) is also increasing. Therefore, in various liquid treatment processes such as plating, even if the entire substrate (19) is inserted into the liquid, air bubbles may remain in the through hole (20) and the liquid may not be immersed in the inner wall of the hole. Since the circulation of the treatment liquid in the through hole (20) is bad, the inner wall of the hole is not uniformly treated, which causes a problem of manufacturing failure of the printed wiring board (19).
