Manufacture method of multi-angle or zero-angle screen printing plate

Abstract

The invention discloses a manufacture method of a multi-angle or zero-angle screen printing plate. The manufacture method comprises the following specific steps of 1) drawing a net and compounding thenet; 2) carrying out a screen printing plate washing treatment; 3) performing graph scanning; 4) preparing a film layer; 5) coating an adhesive layer; 6) coating a film; 7)drying; 8) carrying out laser etching; 9) cleaning; and 10) detecting and packaging. By means of the mode, the manufacture method of the multi-angle or zero-angle screen printing plate has the advantages that the contour of theline formed by laser is clear and flat, the line width is uniform, the shape of the painted line is better, and has obvious advantages compared with conventional plate making; the polymer composite layer is not easy to fall off, so that the plate making yield is greatly improved; when the screen printing plate is used, the film layer is not easy to wear and break, the printing life is prolonged by more than one time, the printing lines in the later period cannot be expanded, and the efficiency of the battery piece is obvious; and the manufactured screen printing plate line is better in ink permeability, so that the limitation of the high-precision narrow line width can be greatly reduced, the printing is good, the line type is good, and the efficiency of the battery piece is improved moreobviously.

Problems solved by technology

The screen produced by this method has certain limitations: 1. The resolution of the photosensitive emulsion under the action of light is not easy to grasp, and the flatness of the edge of the line after exposure and development is not good, and it is easy to affect the printing quality of the line when used; 2. The adhesion between the emulsion and the steel mesh yarn is not good, and it is easy to cause the plate emulsion to fall off after exposure and development, which greatly affects the plate-making yield; 3. The abrasion resistance of the emulsion is not good, and the friction with the substrate during printing is easy to wear and leak, which affects Surface printing quality and service life; 4. The lines are greatly affected by the stability of light energy during exposure, which can easily lead to uneven line thickness, which affects the production yield during mass production and affects printing stability during use; 5. Emulsion penetration Due to the influence of ink properties, the printing line cannot be narrowed to a narrower range, which cannot meet the requirements of high-precision fine line printing

However, with the reduction of the opening of the sub-grid line, due to the inherent defects of the traditional mesh screen (biased stretched net), the occlusion disadvantages of the net knot become more and more obvious, which will inevitably affect the ultra-fine grid printing and the further change of the sub-grid opening. The narrow trend, so the photovoltaic industry's demand for the no-network version is becoming stronger and stronger
