Constitute conventional composite type mask plate silk screen be Weaving type metal gauze or polyester webs etc., this type of silk 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 starch inequality；In the manufacturing process of actual mask plate, generally require and first silk screen is extruded, thus reduce this effect of Weaving type silk screen as far as possible.But the ill effect both so operated and longitude and latitude node cannot be avoided completely to bring.
The present invention is primarily directed to this problem and proposes a kind of silk screen, preferably solves problems described above.
Summary of the invention
The technical problem to be solved is in existing accurate printing technology, owing to silk screen used has Weaving type node, cause the problem that the printing of patterned mask plate is uneven, the present invention provides a kind of new printing screen plate, the silk screen of this half tone does not have Weaving type node, smooth surface, has the advantage that printing uniformity is high.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows: a kind of Printing screen, including flat screen, it is characterized in that the net area of described flat screen is divided into masked area and graph area, described masked area is made up of polygon or circular array, described graph area is made up of the lines that the thin grid line of solar battery sheet Printing screen is corresponding, described lines are made up of bridging array, described bridging array forms specific pattern in described graph area, and described bridging array grid is difform combination pattern；At described masked area and described graph area intersection, the bridging unit of described graph area with the array element structure of described masked area by 1:(1～5) proportioning be connected.
In technique scheme, preferred technical scheme is, constitute described screen net structure is shaped as positive six polygons, tetragon, circle, triangle；The bridging unit of described graph area is 1:2 with the connection proportioning of the array element structure of masked area.
Described tetragon is square, rectangle, rhombus or other parallelogrames, and bridging region is that the grid lines of tetragon interrupts being formed；Being connected by described bridging array between the Polygonal arrays of described masked area, described bridging array is bridge line, connects polygonal angle point；The bridge line line footpath r1 of described bridging array is 10um≤r1≤r2≤80um with the line footpath r2 size range of the web lines constituting described masked area；The mesh number of the polygon or circular array that constitute described masked area is 100～800 mesh；The line footpath r1 of described bridge line is 15um≤r1≤r2≤40um with the line footpath r2 size range of the web lines constituting described masked area；The mesh number of the polygon or circular array that constitute described masked area is 200～400 mesh；The grid lines line footpath constituting described flat screen graphics field is uniform；Described flat screen line is for linking up without Weaving type node silk screen；On flat screen, the web lines line footpath of graphics field is not more than the web lines line footpath in non-graphic region.
In technique scheme, preferred technical scheme is, the grid lines line footpath constituting described flat screen graphics field is uniform；Stress buffer strip and the lateral opening band being connected with buffer strip it is provided with in the periphery in non-grid district；Described flat screen line is for linking up without Weaving type.Described flat screen mesh number is 200～450 mesh, and line footpath a size of 15～30um, thickness is 15～30um；On flat screen, remaining web lines line footpath in graphics field is not more than the web lines line footpath in non-graphic region；On described flat screen, the web lines line footpath of graphics field bridging array is uniform or two is thick greatly middle thin.
Preferably technical scheme is that the structure of described flat screen is formed in one, smooth surface, without the longitude and latitude node of Weaving type.Described flat screen is to be prepared by electroforming process, and its material is pure nickel material or nickel-bass alloy material.
The technical scheme that present invention additionally comprises is as follows: a kind of mask plate using above-mentioned flat screen to prepare, it is characterised in that the opening size of described mask plate graphics field is not more than on described flat screen the size of the web lines absent region of corresponding figure.
In technique scheme, preferred technical scheme is, the figure lacking grid lines composition described in flat screen is one group of lines being parallel to each other, and it is corresponding with the thin grid line of mask plate.
The flat screen that the present invention provides, it has the advantage that 1, described flat screen is to be prepared by electroforming process, it has surfacing, characteristic without establishment type longitude and latitude node, by its electrode of solar battery Printing screen made at printing slurry at present uniformly；2, described flat screen is in region corresponding to the thin grid line of corresponding electrode of solar battery Printing screen without the grid lines on direction, thin grid line place, decreases the flat screen inhibition to printing slurry.
The metal gauze of non-woven, silk screen smooth surface, its mask plate made will not be due to the uneven damage causing mask plate on surface during cleaning wiping.Silk screen can design different percent opening, web lines footpath size and web lines shapes as required, is ensureing also can ensure while silk screen has the most lower slurry effect the life-span of silk screen.Based on above advantage, the electrode of solar battery Printing screen that described flat screen prepares further can print " depth-width ratio " preferably silicon solar battery electrode grid line structure, it is conducive to solar battery sheet to the collection of electric current and transmission, thus has been correspondingly improved the transformation efficiency of solar battery sheet.
The grid lines density degree constituting described flat screen masked area and graph area is adjustable, and i.e. at masked area and graph area intersection, the bridging unit of graph area is connected according to a certain ratio with the array element structure of masked area.It is to say, the grid lines end points in masked area with graph area intersection not all masked area all has bridged linkage to be attached thereto.It is so designed that it has the advantage that the flat screen for same effect requirements, it is ensured that in graph area, the density degree of bridging the most i.e. can reach effect；If the array element (such as rectangle, circle, hexagon etc.) now adjusting masked area is suitable to size, then while can having same performance ensureing silk screen, it may have preferably mechanical resistance hot strength.
