Description
Technical field
The invention belongs to silver slurry printing technology, be specifically related to a kind of capacitive touch screen silver slurry circuit typography.
Background technology
In capacitive touch screen (English abbreviation: TP) industry, domestic capacitive touch screen produces accepts whole world demand
More than the 90% of amount, wherein the internal current derivation passage overwhelming majority uses printing silver slurry to realize.
Existing capacitive touch screen electric current is derived in the silver slurry typography of passage, the most as shown in Figure 1.Fine rule is starched at silver
During the printing of road, printing according to golden finger direction (namely direction of arrow), in printing process, need repeatedly to adjust machine, adjusting machine time is long,
And the fine rule lines instability printed, easily occur that burr and printing process easily occurring, silver slurry infiltrates into printing screen plate
Another side.What is more important, in printing process, easily occurs that line between adjacent fine rule causes short circuit.
For this reason, it is necessary to existing technique is improved, to improve silver slurry printing effect.
Summary of the invention
The printing lines existed for the slurry circuit printing of current capacitive touch screen silver are unstable, burr, silver easily occur
Slurry infiltrates into there are the problems such as line between printing screen plate another side and fine rule, embodiments provides a kind of condenser type
Touch screen silver slurry circuit typography.
In order to realize foregoing invention purpose, the technical scheme of the embodiment of the present invention is as follows:
A kind of capacitive touch screen silver slurry circuit typography, the printing surface being at least included in elargol printing screen plate attaches one
Layer pad carries out the step of silver slurry printing again；Described pad attaches along elargol line direction.
Capacitive touch screen silver slurry circuit typography in above-described embodiment, by attaching one layer to printing screen plate surface
Pad, the height at padded golden finger, facilitate printer hand adjustment machine；And adjust print direction, prevent printing fine line Lu Shiyin
Slurry infiltration causes elargol the phenomenons such as line, burr, infiltration occur, such that it is able to reduce the workload at elargol repair station, and fall
The short-circuit risks that low Sensor elargol line causes, promotes the yields of Sensor functional test.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of capacitive touch screen silver slurry circuit printing screen plate in prior art；
Fig. 2 is capacitive touch screen silver slurry circuit printing screen plate part A enlarged diagram in prior art；
Fig. 3 is the structural representation that embodiment of the present invention capacitive touch screen silver slurry circuit printing screen plate attaches pad.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
As it is shown on figure 3, present example provides a kind of capacitive touch screen silver slurry circuit typography, at least it is included in
The printing surface of elargol printing screen plate 1 attaches one layer of pad 2 and carries out the step of silver slurry printing again；Described pad is along elargol line direction
Attach.
In any embodiment, also include first elargol printing screen plate 1 being carried out, it is to avoid because printing screen plate 1
Unholiness and cause in printing process elargol line that protruding or pit occurs.
In a preferred embodiment, the thickness of pad 2 is 0.15～0.25mm, and width is 0.5～1.0cm.When pad 2
When thickness is more than 0.25mm, printing screen plate scraper is during scraping, and silver slurry is uneven；And the thickness of pad 2 is less than 0.15mm
Time, silver slurry is susceptible to infiltration.
In a preferred embodiment, pad 2 is impermeable adhesive tape.It is further preferred that impermeable adhesive tape is polyester tape.
The impermeable adhesive tape periphery of this type straight, easily tear up, do not stay cull.
On the premise of above-mentioned pad, the embodiment of the present invention preferably silver slurry viscosity is 1100～1800dPa.s.Viscous at this
In the range of degree, during silver slurry printing, elargol line is smooth, and without infiltration, burr, breach etc. is bad, and after baking, elargol adhesive force is strong.
For reaching printing effect, the mesh number of the elargol printing screen plate used in the present embodiment is 400～500 mesh.
It is further preferred that the elargol line width of printing is 80～150 μm；Distance between centers of tracks is 80～120 μm.Live width, line-spacing
The biggest more easily print, and printing elargol line effect is the best, otherwise, live width line-spacing is the least, and printing difficulty increases, elargol line effect
Can be deteriorated, for improvement printing effect, use the embodiment of the present invention preferred live width line-spacing, can obviously improve the silver after silver slurry printing
Tree lace effect
By above-mentioned to pad and pad parameter, silver slurry viscosity, elargol printing screen plate and elargol live width and the limit of distance between centers of tracks
Fixed, at padded golden finger height, silver slurry infiltration when preventing printing, prevent the bad phenomenon such as elargol line, burr, from
And the capacitive touch screen silver slurry circuit typography work at elargol repair station of the embodiment of the present invention can be shortened in a large number
Reduce the short-circuit risks that Sensor elargol line causes, promote the yields of Sensor functional test.
Below by way of multiple embodiments illustrate the embodiment of the present invention capacitive touch screen silver slurry circuit typography,
Effect and the effect reached.
Embodiment 1
A kind of capacitive touch screen silver slurry circuit typography.Wherein, the silver as it is shown on figure 3, silver paste printing ink thaws → checks
Slurry printing screen plate → attach impermeable adhesive tape → frame version → tune machine → examination printing, inspection printing effect → measurement live width line-spacing → print
Brush silver slurry → recovery ink → remove impermeable adhesive tape → cleaning half tone.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, within all should being included in protection scope of the present invention.
