クリーン印刷が行なわれる。 Generally, wiring patterns of electronic components, heat generating layers of thermal printing heads, conductive layers, insulating layers, etc. are sometimes formed by screen printing. A printing screen is used for such screen printing. This printing screen is made by braiding thin wires of stainless steel, polyester, etc. into a mesh, which is then fixed into a frame. In order to form a desired print pattern on a substrate using this printing screen, for example, as shown in FIG. On the other hand, a printing paste 3 containing metal powder is placed on the other surface of the printing screen 1, and a squeegee 4 is slid in contact with the printing screen 1 at a predetermined printing pressure. This spreads the printing paste 3, so that the printing paste 3 that has passed through the portions of the printing screen 1 where the emulsion 2 is not present is deposited on the substrate 5. Screen printing is performed in this manner.

まり等を起こすなどして印刷精度が損なわれる。 By the way, in the conventional printing screen 1, the material such as stainless steel is exposed as it is, so when the squeegee 4 is slid, the contact resistance with the printing screen 1 becomes large, and a force exceeding the sliding force originally required for printing is generated. A load is applied to the printing screen 1. If this frictional force is large, the elastic limit of the material is exceeded and the printing screen 1 is deformed. That is, the printing screen 1 is stretched or wrinkled, the printing pattern is distorted, the printing screen 1 becomes clogged, etc., and printing accuracy is impaired.
本考案は上記の問題点に鑑みてなされたもので

らない。 The printing screen 10 of this embodiment has a mesh 14 formed by braiding thin wires 12, 12, etc. of stainless steel, polyester, etc., and a frame 16 is attached to the outer periphery of this mesh 14. Further, a coating 18 having an anti-friction effect is formed on one side 14a of the mesh 14, that is, the side that comes into contact with the squeegee. This coating 18 is formed by depositing a metal oxide such as molybdenum dioxide (MoO 2 ) by sputtering or vapor deposition. The film thickness is preferably a thickness that does not impair printing accuracy or passage of the printing paste, particularly about 100 Å to 10 μm. Therefore, in screen printing, printing paste is placed on one side 14a of the mesh 14 of the printing screen 10 provided with the coating 18, and a squeegee is slid on the surface 14a. Since the film 18 is interposed between the squeegee and the thin wires 12, 12, .

できる。 In the above embodiment, the coating 18 was formed only on one side 14a of the mesh 14.
It is also possible to form a coating on both sides of 4.
In addition, the thin wires 12 and 1 before being braided into the mesh 14
It is also possible to form the coating 18 on the printing screen 10 in advance and then knit it into the mesh 14 to form the printing screen 10.

効果が得られる。 As described above, according to the present invention, since a metal oxide coating having a friction reducing effect is formed on at least one side of the mesh, the squeegee slides extremely smoothly during printing, and almost no extra load is applied to the printing screen. . Therefore, the excellent effect that deformation of the printing screen is reduced and printing can be performed with high precision over a long period of time can be obtained.
