Since it moves in synchronization with the printing squeegee, the flow rate can be stabilized and the paste can be applied evenly. Furthermore, since the stage is provided with holes that correspond in position to the through-holes of the substrate, there is no possibility of paste scattering due to convection on the backside of the substrate or short-circuiting with adjacent through-holes.

け少なくすることにより、空気の吸い込み量のバラツキ
を押え、安定したペースト塗布量を得ることができる。The operation of this embodiment will be explained below. The substrate 1 is positioned and fixed on a stage θ having a suction hole slightly larger than the through-hole hole 2, at the same position as the through-hole hole 2, and having the same number of holes. Next, the printing mask 3 is superimposed on the substrate 1, and the squeegee 4 is pushed onto the printing mask 3. At the same time, the pressure is reduced in the cavity 9 of the suction chamber 8 under the stage 6, and at least the through hole is removed. A squeegee 4 and a suction chamber 8 are synchronized and moved in the same direction while suctioning the through-hole hole 2 including the front and rear of the hole, and the paste 6 is continuously applied to the diameter inner surface of the through-hole hole 2. Here, the adjustment plate 10 brings the stage 6 and the suction chamber 8 into close contact with each other to prevent air from being trapped, and also changes the suction conditions by changing the area of the suction opening. , the conditions are changed to the optimum conditions depending on the number of holes. In this way, by minimizing the number of through-hole holes 2 that are temporarily sucked during through-hole printing, it is possible to suppress variations in the amount of air sucked in and obtain a stable amount of paste application.

スルーホール穴との短絡不良を防止することができる。In addition, by making the suction hole 7 at the same position as the through-hole hole 2 in the stage 6 a little larger, the phenomenon of the paste 5 suddenly coming out directly behind the substrate 1 can be alleviated, and the scattering of the paste can be prevented. It is possible to prevent contamination on the back surface of the board and short-circuiting with adjacent through-holes.

定したスルーホール印刷が得らｎる。In addition to the above, by providing the through-hole printing device with a flow rate regulating valve 11 that can change the through-hole suction amount and a mechanism that controls the moving speed of the squeegee 4, more stable through-hole printing can be obtained.

したスルーホール印刷が行なえる。In FIG. 2, the suction changeover switch 12 is set to side A during paste printing, and then set to side B after the printing mask has completely interacted with the substrate after printing, and through-hole suction is performed in two stages. As a result, at the end of the first stage, the necessary amount of ink can be secured on the inner surface of the through-hole hole 2, as shown in Figure 3a, and at the end of the second stage, the through-hole can be secured as shown in Figure 3. The inner surface of the hole 2 is uniformly coated with the paste 6. Here, each of the suction amounts in the first stage and the second stage can be adjusted by a flow rate adjustment valve 11. As described above, by dividing the through-hole suction into two stages and making it possible to adjust the flow rate at each n stage, uniform and stable through-hole suction can be achieved without increasing the capacity of the suction pump or drastically reducing the squeegee speed. Hole printing is possible.
