Problems solved by technology

Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has emerged. The basic structure of the screen is eternal, that is, the screen frame, the missing printing screen and the photosensitive material for printing are integrated, and the three are indispensable; and at present, exposure on the screen The method is generally to paint photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose the photosensitive glue on the mesh through negative film exposure, and get the screen printing pattern after washing. The photosensitive glue in this way is directly painted on the mesh, the stability is not good, the photosensitive glue is unevenly painted and the thickness cannot be controlled, which affects the printing performance of the printed pattern

Embodiment Construction

[0024] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as Figures 1 to 4 Shown, a kind of screen making method, the steps are as follows:

[0026] S1. Wire mesh weaving: Weave multiple metal wefts and multiple metal warps in an up-and-down staggered manner to form a mesh; the metal warps and metal wefts are made of stainless steel, tungsten steel, titanium, aluminum, copper One of nickel and nickel, the metal warp and metal weft made of aluminum can be selected in this embodiment.

[0027] S2. Stretching the net: the metal weft and the metal warp are stretched with tension and fixed on a screen frame to form a screen.

[0028] S3, prefabricated photosensitive film: choose a base film 1, evenly sprinkle activated alumina powder 5 on the base film 1, spray the first layer of photosensitive adhesive 2 on the base film sprinkled with activated alumina powder 5; The middle position of la...

Abstract

The invention discloses a method for making a screen plate, the steps are as follows: S1, screen weaving; S2, stretching the net; S3, prefabricated photosensitive film; S4, pasting the photosensitive film; S5, cutting and tearing film; S6, exposing; Provided is a method for making a screen plate with good photosensitive adhesive coating stability, uniform coating and controllable thickness.

Description

technical field [0001] The invention relates to a screen making method. Background technique [0002] Screen printing technology is an ancient civilization and a long-lasting industry, which is widely used in people's production and life. Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has emerged. The basic structure of the screen is eternal, that is, the screen frame, the missing printing screen and the photosensitive material for printing are integrated, and the three are indispensable; and at present, exposure on the screen The method is generally to paint photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose the photosensitive glue on the mesh through negative film exposure, and get the screen printing pattern after washing. The photosensitive glue of the above methods is all directly painted on the mesh, the stab...
