Problems solved by technology

[0006] However, since a stainless steel mesh is used as a support body, the recovery of the position coordinates after being deformed by the pressure of the squeegee is not good, and the printed pattern is easily distorted.
As a result, it is difficult to obtain the desired printing accuracy
In addition, the s

Example Embodiment

[0044] figure 1 The first embodiment of the combined screen plate for contact printing of the present invention is shown. The combined screen plate 1 includes: a frame 2; a printing screen 3; and a support body 4. The inner periphery of the support 4 is joined to the outer periphery of the printing screen 3, and the outer periphery of the support 4 is fixed to Box 2.

[0045] The frame 2 is formed into a quadrangular frame shape by a member having a thickness, and is formed into a size that allows the squeegee to move inside the frame 2. The material of the frame 2 is formed of a metal material such as aluminum or aluminum alloy. In the conventional screen printing board, the frame 2 has a function of maintaining the tension of the printing screen 3, but in this embodiment, the support 4 maintains the tension of the printing screen 3. Therefore, the support body 4 has a function of firmly supporting the printing screen 3 to the frame 2.

[0046] As the screen 3 for printing, a m...

Abstract

A combined screen plate suitable for contact printing is capable of performing high-precision printing and is high in durability. The combined screen plate (1) includes: a frame (2); a printing screen(3); and a support (4), wherein an inner peripheral portion of the support (4) and an outer peripheral portion of the printing screen contact, and the outer peripheral portion of the support (4) is fixed to the frame. The printing screen (3) is a metal screen, and compared with the printing screen, the support (4) is formed of, during scraping, a metal sheet which has smaller stretching in the planar direction and a smaller amount of displacement in the thickness direction and is high in strength. Therefore, the combined screen plate (1) can be obtained, can suppress stretching of the printing screen (3) in the planar direction during contact printing, and is high in the precision and durability.

Description

technical field [0001] The present invention relates to a combination screen plate used in contact screen printing. Background technique [0002] In screen printing, in order to cope with fine wire printing (Japanese: ファインライン printing), the thinning of the screen is promoted, and the direct bonding of the printing screen directly to the frame in order to use a low-strength and expensive screen Compared with the structure, the wire mesh panel with combined structure has become the mainstream. The combined screen board is a member that fixes the periphery of the printing screen to the frame via a support. [0003] In the case of a combined screen board, since the load of the printing screen is absorbed by the support during printing, a synthetic fiber screen with more elasticity than the printing screen is generally used as the support (such as , Patent Document 1). [0004] However, due to the miniaturization and multifunctionalization of electronic components in recent ye...
