Abstract
The invention discloses a panel silk screen with a corner transition structure. The panel silk screen with the corner transition structure is adaptable to the printing industry and is different to a conventional silk screen corner structure, a non-perpendicular transition structure, a finer mesh density or a different radius of the silk and an optical combination of the three arrangements are adopted in an original area by the corner transition structure. The conventional silk screen corner structure is a perpendicular right-angle structure conventionally, in operations of requiring large tension on the silk screen, local breaks occur to the corner areas and result in the finished product quality problem, and the unqualified rate is increased; by the aid of the panel silk screen with the corner transition structure, the problem can be avoided, service life of the panel silk screen can be prolonged, and the qualified rate of products can be increased.
Description
Technical field
The present invention relates to the electronic printing field, especially relate to a kind of plane silk screen.
Background technology
High-accuracy plane silk screen can be used for printing industry, because it is generally to make by techniques such as electroforming, have one-body molded, characteristic without Weaving type longitude and latitude node, can replace the silk screen of Weaving type in higher application link at many print requests, the transitional region of normally used silk screen between silk screen district sideline confluence and sideline, non-silk screen district cross is often the straight vertical corner structure, therefore at some silk screen tension force, require in larger operation, the phenomenon that there will be partial fracture, thereby cause descend the service life of silk screen, the product fraction defective promotes greatly, greatly increased production cost.
