Printing technology of knotless screen

Abstract

The invention provides a printing technology of a knotless screen. The knotless screen comprises a screen frame, a plurality of longitude lines and latitude lines are fixed into the screen frame, the parallel longitude lines are perpendicularly interwoven with the parallel latitude lines, the contact positions between the longitude lines and the latitude lines are bonded and fixed, the two ends of the longitude lines and the latitude lines are fixed to the screen frame, a printing pattern is arranged in the middle of the screen frame, and fine line printing silver slurry is adopted for printing, wherein the width of each longitude line or each latitude line is 30 [mu]m. According to the printing technology of the knotless screen, compared with a conventional screen printing, the situation that knots hinder the ink permeability is avoided, the grid line width of the longitude lines and the latitude lines on the screen can be made 30 [mu]m or below under the condition that using conditions of the screen are not changed, the depth-width ratio is optimized, a silver slurry using window is expanded, then the fine line printing silver slurry is used cooperatively, and the efficiency can be improved by 0.15% or over.

Description

technical field [0001] The invention relates to a printing process of a knotless screen plate. Background technique [0002] Screen printing, also known as screen printing, is widely used because of its unified production method and simple equipment. Screen printing mainly includes two kinds of net-knot screen printing and net-knot screen printing, and the net-knot screen technology can make the ink penetrate during printing because there is no net knot between the lines during the production process. Better performance, better vertical effect after printing, thinner grid lines, the focus is to improve the conversion efficiency of the final cell during wafer printing, but its disadvantage is that the production process is cumbersome, and the output is higher than that of conventional screens. Production is about twice as slow. [0003] How to reliably improve the printing effect and improve production efficiency is an urgent problem to be solved. Contents of the inventio...
