Manufacturing method of high-opening SE net-knot-free screen printing plate

Abstract

The invention discloses a manufacturing method of a high-opening SE net-knot-free screen printing plate. The manufacturing method comprises the following steps of piece cutting, net aligning, film laminating, pressing, net opening, scanning, laser removing, coating, film layer laser removing, alignment exposure, inspection and shipment. According to the method, the gauze in an effective area of apattern is removed at a fixed point by using laser, so that the film raw material cost is greatly saved, the overall platemaking time is saved, and the platemaking efficiency is improved; meanwhile, the gauze in the corresponding area is removed through lasers, poor screen printing plates and raw material scrapping caused by the screen stretching process are reduced, the production cost of a company is reduced, meanwhile, a scanning program and a laser removing program run synchronously, and the existing platemaking working hours are reduced; and the gauze in the area corresponding to the pattern is removed by laser without changing the pattern of a client, so that a net-knot-free screen printing plate required by SE technology printing can be manufactured.

Description

technical field [0001] The invention relates to the technical field of screen making, in particular to a method for making a high opening SE knotless screen. Background technique [0002] The existing knot-free production generally goes through processes such as net cutting, aligning the net, fixing the net, cutting, pressing, stretching, scanning, coating, alignment exposure, development, and inspection. [0003] Combined with the existing process, since the knot-free process requires that each mesh in the warp direction must maintain a certain level, and the fluctuation range is within 50 μm, so the process requirements for the mesh are particularly strict. It consumes a lot of man-hours, and at the same time, a lot of mesh yarns will be scrapped due to alignment deviation, resulting in waste of raw materials. At the same time, the well-aligned mesh will also cause a certain mesh offset during the netting process, resulting in the difficulty of alignment exposure. At the ...

[0003] Combined with the existing process, since the knot-free process requires that each mesh in the warp direction must maintain a certain level, and the fluctuation range is within 50 μm, so the process requirements for the mesh are particularly strict. It consumes a lot of man-hours, and at the same time, a lot of meshes will be scrapped due to the offset of the alignment, resulting in waste of raw materials

At the same time, the well-aligned mesh will also cause a certain mesh offset during the netting process, resulting in the difficulty of alignment exposure. At the same time, due to the increase in offset, it will cause customer printability problems and affect customer products. electrical performance, which leads to the reduction of customer product quality. In addition, the serious deviation of the net will cause part of the mesh to be scrapped.

The alignment exposure process is difficult and demanding. Since the no-network process requires that each line width must be aligned between two meshes, an electron microscope is required to magnify the alignment during the alignment exposure process, which takes a lot of time. Working hours and manpower, and due to the special scanning process of the non-network stretching process, each screen must correspond to a film negative, which increases the production cost of the film and indirectly increases the customer's manufacturing cost

At the same time, due to the scanning of the non-network graphics, the straightness of the customer's graphics is fine-tuned, so it cannot be applied to the printing of SE cells
