When performing screen printing on a printed wiring board, in conventional screen printing machines, the printing plate is set by visually matching the printed shape of the printed wiring board with the printing shape of the printing press plate. The pattern drawn on the machine plate is not easy to see, especially when the printed wiring board is placed under the plate, and the light from the printing table side cannot pass through. Therefore, rough alignment is performed, and then the actual ink or The method of correcting the position by printing a coating material such as solder paste has been necessary, and it takes time to align the position.

An embodiment of the present invention will be described with reference to the drawings. First, to explain the printing press plate, 8 in Fig. 3 is a printing press plate made of silk screen or stainless steel, and is fixed to a frame 9 made of aluminum or the like. , a plate opening 10 for printing a pattern at a planned printing position 2 of the printed wiring board 1, and at least two positioning openings 11 corresponding to the positioning holes 3 provided in the printed wiring board 1 are arranged in a predetermined position. It is formed by positional relationships. Incidentally, if the printing press plate 8 is a silk screen, the plate opening 10 and the positioning opening 11 are formed by applying resin or the like to the parts excluding the plate opening 10 and the positioning opening 11.
In the case of stainless steel, the plate opening 10 and the positioning opening 11 are formed by drilling holes in the stainless steel.

設ける必要がある。 By the way, the planned printing position 2 of the printed wiring board 1
A coating material such as paste solder is printed on the plate, and in order to do so, it is necessary to align the plate opening 10 with the intended printing position 2 without any error. Therefore, in the present invention, the positioning opening 11 is composed of a square inner opening 12 and an outer opening 13 provided to surround the inner opening 12, and the size of the square inner opening 12 is printed. The diameter of the positioning hole 3 of the wiring board 1 is sized to form an inscribed circle. still,
When forming the inner opening 12 and the outer opening 13, there is no problem when using silk screen, but when using stainless steel, it is necessary to provide a bridge 17 as shown in FIG.

The plate opening 10 is placed on the printed wiring board 1 and the positioning hole 3 provided in the printed wiring board 1 is visually aligned with the square inner opening 12, thereby aligning the plate opening 10 with the planned printing position 2. can be matched. In this case, since the inner opening 12 is formed to a size such that the diameter of the positioning hole 3 is the inscribed circle, mutual positions are easy to see and alignment is easy, and the inner opening 12 is surrounded. Since the outer opening 13 is formed, even if the position of the positioning hole 3 is significantly shifted, it can be easily found.

布材を印刷予定位置２に印刷することができる。 Next, a method for actually aligning the above-mentioned printing press plate 8 and printed wiring board 1 will be explained. First, in FIG. A through hole 16 is provided in the printing table 14 so as to correspond to the positioning hole 3, and a light source is provided below the through hole 15. Therefore, when the printed wiring board 1 is placed on the printing stand 14 so that the positioning hole 3 of the printed wiring board 1 is positioned above the through hole 15, the light from the light source 16 passes through the through hole 15 and the positioning hole 3. It turns out. Therefore, when the printing press plate 8 is stacked on the printed wiring board 1, the light passing through the positioning holes 3 can be visually observed from above the printing press plate 8 through the positioning openings 11, so that the positioning holes 3 You can easily check the location of In other words, even if the positioning hole 3 is misaligned with the inner opening 12 of the positioning opening 11 to the extent that it does not overlap at all, the positioning hole 3 is an outer opening provided so as to surround the inner opening 12. 13 and the light passes therethrough, the position of the positioning hole 3 and the direction of deviation can be easily determined. Therefore, the printing press plate 8 can be moved while checking the direction of deviation. By moving,
The diameter of the positioning hole 3 can be accurately inscribed in the inner opening 12 of the positioning opening 11 of the printing press plate 8. As a result, the plate opening 10 of the printing press plate 8 precisely matches the intended printing position 2 of the printed wiring board 1, so that a coating material such as paste solder can be printed at the intended printing position 2 in this state.

As explained above, the printing press plate of the present invention has a double positioning opening consisting of an inner opening and an outer opening, and the inner opening is arranged so that the diameter of the positioning hole of the printed wiring board is the same as the inscribed circle. Because it is square, the positional relationship between the positioning holes and the positioning openings can be easily determined, and when aligning the printing press plate and the printed circuit board, the positioning openings of the printing press plate can be easily aligned. Even if the positioning holes of the printed wiring board are misaligned to the extent that they do not overlap at all with respect to the inner openings that form the Since the position and direction of deviation can be easily determined, the diameter of the positioning hole of the printed wiring board can be accurately inscribed in the square inner opening of the printing press plate at once.
従つて、従来のように何度も修正を行うことな
