Abstract
The utility model relates to the technical field of a screen for manufacturing a conductive thin thread, and particularly to an ultra-small-thread-diameter metal thread screen which comprises a thread net, a nylon net and a net frame. The net frame is adhibited with the nylon net, and furthermore the nylon net is adhibited with the ultra-small-diameter metal thread screen through glue. The thread net is a metal thread net with ultra-small thread diameter and ultra-high mesh number. The thread diameter is smaller than or equal with 14 mu m, and the mesh number of the metal thread net is larger than or equal with 380 meshes. The net frame is square and is made of aluminum or cast iron. According to the ultra-small-thread-diameter metal thread screen, a routine metal thread net is replaced by the Ultra-small-thread-diameter metal thread net for forming the screen. The open width of screen pattern is 50 mu m. The width of a conductive silver thread after printing is 70 mu m. Simultaneously no broken point exists on the conductive silver thread. Furthermore the ultra-small-thread-diameter metal thread screen has high surface smoothness.
Description
Technical field
The utility model relates to conduction fine rule manufacture half tone technical field, especially a kind of ultra-fine wire diameter metal gauze net version.
Background technology
Printing conductive silver line is widely used at microelectronic, and such as crystal silicon solar batteries, conductive silver wire is printed on cell piece surface, is used for collected current.On touch screen surface, conductive silver wire touches electric signal transmission panel surface and processes to processor inside.
In solar cell is manufactured, conductive silver wire forms with serigraphy conventionally.Pre-configured silver slurry is placed on half tone, utilizes scraper that pressure is provided, silver slurry was pressed to half tone figure opening, print on the silicon chip that is placed on bottom.The silver slurry seeing through reflects the figure on half tone, forms the conducting channel of collected current on silicon chip.In Trackpad is manufactured, same print principle for forming touch screen circuit on substrate.Figure on half tone is to realize by the mode of exposure imaging.
Silver-colored lines positive on solar battery sheet are comprised of two parts: main grid line and secondary grid line, and secondary grid line is comprised of tens to 100 approximately tens microns of wide lines, for collecting the photogenerated current of silicon chip surface; Main grid line is comprised of two to the five wide lines of 0.8～2 millimeter, for collecting the electric current on secondary grid line and importing to the circuit being used.But the existence of silver-colored lines, has reduced silicon chip and has been subject to the effective area of light, so lines are more carefully better.
In industry, the figure A/F design load of screen printing screens is at 50～60um at present, and after printing, silver-colored conductor width is at 80～90um; When further reduction half tone figure A/F, as 40～50um live width, the large wire diameter (wire diameter >=16um) of common metal silk screen, the negative effect of large anastomose starts to highlight, the China ink of crossing of half tone worsens, conductive silver wire starts to occur the problems such as breakpoint, poor flatness, has a strong impact on the electric conductivity of conductive silver wire.
Utility model content
The technical problems to be solved in the utility model is: use common metal screen printing, the figure A/F limiting value of half tone is 50～60um, and after printing, silver-colored conductor width reaches 80um～90um; When further reduction half tone figure A/F, as 40～50um, the large wire diameter (wire diameter >=16um) of conventional silk screen, the negative effect of large anastomose starts to highlight, the China ink of crossing of half tone worsens, conductive silver wire starts to occur the problems such as breakpoint, poor flatness, has a strong impact on the electric conductivity of conductive silver wire.For this problem, the utility model provides a kind of ultra-fine wire diameter metal gauze net version.
The utility model solves the technical scheme that its technical problem adopts: a kind of ultra-fine wire diameter metal gauze net version, comprise silk screen, nylon wire and screen frame, between screen frame and nylon wire, between nylon wire and silk screen, all by glue, stick, described silk screen is comprised of the woven wire of ultra-fine wire diameter, superelevation order number, described wire diameter size≤14um, order number >=380 order.
According to another embodiment of the present utility model, further comprise that being shaped as of described screen frame is square.
According to another embodiment of the present utility model, further comprise that described screen frame is aluminium frame or cast iron frame.
The beneficial effects of the utility model are, use ultra-fine wire diameter metal gauze net version, half tone figure A/F <50um, the width <70um of conductive silver wire after printing, conductive silver wire, without breakpoint, has good surface smoothness simultaneously; By the utility model, for the printing of crystal silicon solar batteries front conductive silver wire, solar cell photoelectric conversion efficiency can improve 0.2%～0.3%, and monolithic silver slurry consumption reduces by 10% simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure 1, screen frame, 2, nylon wire, 3, woven wire, 4, half tone figure.
The specific embodiment
If Fig. 1 is structural representation of the present utility model, a kind of ultra-fine wire diameter metal gauze net version, comprise screen frame 1, nylon wire 2 and woven wire 3, between screen frame 1 and nylon wire 2, between nylon wire 2 and woven wire 3, all by glue, stick, described woven wire 3 is comprised of the woven wire of ultra-fine wire diameter, superelevation order number, described wire diameter size≤14um, order number >=380 order.Being shaped as of described screen frame 1 is square.Described screen frame 1 is aluminium frame or cast iron frame.
The utility model can be as required printing pattern, select suitable screen cloth specification and live width thickness specification.The utility model preferred embodiment one, order number 380, wire diameter 14um, the thick 14um～35um of yarn.The utility model preferred embodiment two, order number 430, wire diameter 13um, the thick 13um～30um of yarn.The utility model woven wire has ultra-fine wire diameter advantage, when further reducing half tone figure A/F, can effectively solve the breakpoint problem that silk screen anastomose causes.The utility model adopts ultra-fine wire diameter woven wire to substitute common metal silk screen composition half tone.Half tone, by the mode of exposure imaging, can manifest half tone figure 4.The half tone figure A/F <50um obtaining, the width <70um of conductive silver wire after printing, conductive silver wire, without breakpoint, has good surface smoothness simultaneously.
By the utility model, for the printing of crystal silicon solar batteries front conductive silver wire, solar cell photoelectric conversion efficiency can improve 0.2%～0.3%, and monolithic silver slurry consumption reduces by 10% simultaneously.
More than, by description of listed embodiment, basic conception of the present utility model and basic principle have been set forth.But the utility model is never limited to above-mentioned listed embodiment, every equivalent variations of doing based on the technical solution of the utility model, improvement and deliberately become of inferior quality behavior, all should belong to protection domain of the present utility model.
