The electroforming flat screen of conventional composite type mask plate is constituted for Weaving type metal plating flat screen or polyester webs etc.,
Such electroforming flat screen can cause the lower slurry effect of final molding mask plate due to the characteristic of Weaving type longitude and latitude node, such as：Under
Slurry is uneven；In the manufacturing process of actual mask plate, generally require first to extrude electroforming flat screen, so as to reduce as far as possible
This effect of Weaving type electroforming flat screen.But the bad effect for both so having operated and cannot completely having avoided longitude and latitude node from bringing
Really.
The present invention proposes a kind of electroforming flat screen primarily directed to this problem, preferably solves problems described above.
The content of the invention
During the technical problems to be solved by the invention are existing accurate printing technology, due to the mechanical resistance of flat screen used
The relatively low problem of tensile strength, the present invention provides a kind of new electroforming flat screen, and the flat screen has preferably machinery tension
Intensity.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：A kind of electroforming flat screen, main body is flat
Face structure, zone line is network, and outer rim is the lateral opening structure for fixing the electroforming flat screen, the electroforming plane silk
The circle or oval-shaped array that are provided with hollow out of net.
In above-mentioned technical proposal, preferred technical scheme is that the figure of hollow out shape is provided with the electroforming flat screen
Shape array, the graphic array of the hollow out shape forms preset pattern on the circular or oval-shaped array region.
Constitute the peripheral bridged linkage 201 or 301 of the part of the non-circular void region 20 or 30 and constitute circular array
The connection of peripheral skeleton 211 or 311 of the part of void region 21 or 31 is coherent.The center spacing of two adjacent circular hollow-out units is d,
20um≤d≤300um；The circular radius of circular hollow-out unit are r, 5um≤r≤150um.
The skeleton size of peripheral edge portion 11 of the electroforming flat screen is big with respect to the skeleton size of zone line, electroforming plane
The peripheral edge portion of silk screen is connected with outside 12, is provided with outside due to fixed lateral opening.Electroforming flat screen surface be coated with or
After overlaying one layer of photopolymer, it constitutes the half tone for printing solar cell piece.Photopolymer is distributed in electroforming and puts down
Subregion in the agent structure of face silk screen and on list structure 10, region that is uncoated or overlaying photopolymer forms hollow out
Shape.The width dimensions D1 of the width dimensions D2≤original list structure 10 of the structure void region of photopolymer is covered with, and is had
25um≤D2≤D1≤300um。
In above-mentioned technical proposal, preferred technical scheme is, the structure of electroforming flat screen be by electroforming process integrally
