課題を有していた。Next, when the current plate 3 is used, the suction strength of the conductive ink is stabilized by the difference in size between the holes 4 and 5 between the circumferential part and the central part of the current plate 3, but When the density of the provided null-holes 7a changes, the amount of conductive ink applied to the inner walls thereof becomes unstable. In other words, the current plate 1
Even if the size and spacing of the rectifying holes 2, 4, and 6 in 3 are changed, if the density of the through holes 7a provided in the printing substrate 7 is not constant, the suction force will partially change. The problem was that the coating amount was unstable and it was difficult to form a uniform conductor layer.

A support plate 6 with holes corresponding to the through holes is attached, and a printing medium 7 with a required number of null holes 7a is placed thereon. In this state, when conductive ink (not shown) is printed on the printing material 7 and sucked through the suction hole 8a provided at the bottom of the printing table 8, the conductive ink flows into the through hole 7a of the printing material 7. It is sucked in and forms a conductive layer on the inner wall of the through-hole a. At this time, if the distribution density of the through holes 7a of the printing material 7 differs within the area of the main current plate 9, the suction force in the null holes 7a of the printing material 7 will change, making it impossible to form a stable conductor layer. In order to keep this suction force constant, the sub-straightening plate 11 is moved, the position with respect to the main rectification plate 9 is adjusted, and the overlapping degree of the main rectification hole 1o and the sub-straightening hole 12 is controlled to adjust the suction force to the printing material. It is made to be constant for any null-hole (Via) of 7.
