Process for cleaning high-precision screen printing plates

Abstract

The invention relates to a process for cleaning high-precision screen printing plates, which comprises the steps of: 1 rapidly taking down a screen printing plate in one minute after printing, and collecting residual silver paste on the screen printing plate in two minutes; 2 simultaneously wiping the front side and the back side of the screen printing plate with non-woven fabric wetted in a TM plate washing agent along the direction of mesh stretching angles; 3 after the both sides of the screen printing plate are cleaned by the TM washing agent, simultaneously wiping the front and the back sides of graphics fields with non-woven fabric wetted in a DM plate washing agent along the direction of mesh stretching angles, 4 checking graphs with lights, if partial graphs are invisible, simultaneously wiping the front and the back sides of the field with non-woven fabric wetted in the DM plate washing agent along the direction of mesh stretching angles, until the graphs are visible, wherein the whole wiping process is not more than ten minutes; and 5 after the screen plating plate is wiped clean, drying the screen printing plate with an ion blower gun. The process can rapidly clean the high-precision screen printing plates completely, and is quite effective to plates with high-precision screen printing silver paste that is difficult to be cleaned, has low cleaning cost, and guarantees the normal production.

Description

technical field [0001] The invention relates to a screen printing screen cleaning process, in particular to a high-precision screen printing screen cleaning process. Background technique [0002] American Sam Hurt invented touch technology in 1971, which brought a novel, easy-to-use human-machine interface, and such an interface can be easily improved and updated to achieve new system features or applications. There are five types of touch screens commonly used at present: resistive, surface capacitive, projected capacitive, surface acoustic wave, and infrared. Apple iPhone and LG Prada mobile phone use projected capacitive touch screen, which brings us a fantastic control experience. The reason why the projected touch screen has such a powerful function is because it has an exquisite structural design, and it is very difficult for the manufacturer of the touch screen to realize these exquisite designs. special material. Among these special materials, the screen printing ...

Problems solved by technology

Due to the smaller gaps and thin graphic lines, the screen is more difficult to clean

At the same time, another important factor affecting screen cleaning is the silver paste used, because the adhesion of the line must meet the requirements of ASTM grade: 5B, so the viscosity of the ink will also increase accordingly. As we all know, the more difficult the ink is bigger, harder to clean

Therefore, the previous conventional screen cleaning process is no longer suitable for routine operations under new conditions.

On the other hand, the price of 500-mesh stencil is quite high, and some even reach 10,000 yuan per piece. The cleaning process of the screen is becoming more and more important. If the screen cannot be cleaned, it will inevitably increase the production cost and affect the normal operation. production operations
