Corner transition structure for flat silk screen

Abstract

The invention discloses a corner transition structure for a flat silk screen in the printing industry. Different from a conventional silk screen corner structure, the corner transition structure is of a non-perpendicular transaction structure, or a structure with finer grid density, or a structure with different grid line diameters or an optional combination of the above three structures in the original corner area. Normally, a perpendicular right-angle structure is adopted as the conventional silk screen corn structure, and in operation requiring large silk screen tensioning force, the corner area partially fractures to cause product quality problems finally, and reject ratio is increased. The corner transaction structure can avoid the above phenomena, service life of the flat silk screen is prolonged, and yield of the products is improved.

Description

[0001] technical field [0002] The invention relates to the field of electronic printing, in particular to a plane screen. [0003] Background technique [0004] High-precision planar screen can be used in the printing industry. Because it is generally produced by electroforming and other processes, it has the characteristics of one-piece molding and no weaving warp and weft nodes. It can replace the weaving type in many applications with high printing requirements. Wire mesh, the transition area between the edge intersection area of ​​the wire mesh area and the edge line intersection of the non-screen area is often a vertical right-angle structure in the commonly used wire mesh, so in some operations that require a large wire mesh tension, local cracks will occur The phenomenon, which leads to the decrease of the service life of the screen, greatly increases the defective rate of the product, and greatly increases the production cost. [0005] figure 1 Shown is the over...

AI Technical Summary

Problems solved by technology

When the wire mesh is subjected to a large external tension, the uneven force here will easily cause the wire mesh to break, making the wire mesh scrapped and affecting the final product
