Circuit moulding process.
Background technology
Touch screen is also known as " touch screen ", " touch panel ", is a kind of induction type liquid of the input signals such as receivable contact
Crystal device, when contacting the graphic button on screen, the haptic feedback system on screen can be according to the journey of preprogramming
Formula drives various connection devices, is substituted for mechanical push button panel, and produces by liquid crystal display picture lively
Visual and sound effects.Touch screen is as a kind of newest computer input apparatus, it is most simple at present, conveniently, naturally one kind is man-machine
Interactive mode.It imparts multimedia with brand-new looks, is extremely attractive completely new multimedia interactive equipment.Main application
In the inquiry of public information, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, premises
Produce presell etc..
In general, there are mainly three types of the forming methods of the pattern conductive circuit inside touch screen：The first is yellow light
Micro-photographing process technology, using crosslinking (cross-linking) is generated after photoresistance exposure, collocation development, etching technique are formed conductive
Circuit, this production method is slow and production technology is complicated, while can cause the problem of environmental pollution of spent acid salkali waste；Second method
It is to utilize printing technology, is directly printed on glass or film via halftone using electrically conductive ink, this method must largely use halftone,
It often designing a kind of circuit and just needs to manufacture a kind of halftone and limited for fear of halftone material, line width minimum can only achieve 50 μm,
It cannot be satisfied touch screen narrow frame design demand；The third method is to carry out patterning process using the printing of radium-shine auxiliary, is first printed
After the large stretch of conductive film of brush, then laser engraving is carried out, using the principle of radium-shine etching conductive film, completes the demand of one patterned,
It is radium-shine to take 1064nm or 532nm wave spectrums more, but this method also has the limitation that program complexity and line width are unable to reach 30um.
For touch screen, the best material of pattern conductive circuit is Jin Heyin, because having good chemical stability
And low-resistivity, but gold is of high cost, so being mostly used silver to make conductive ink.The silver ink water now used is mostly with silver ink
In the majority, mainly particle silver is dispersed in solvent, and carrier (TiO is added2Deng) or reducing agent etc., nano silver is adsorbed onto on carrier and is formed
Particle.Because the resistivity of conductive film can be influenced containing nonconducting carrier, need (general using high temperature sintering in processing procedure
More than 200 DEG C), so that particle of the surface with silver ion is uniformly distributed arrangement, reduces impedance.This process costs are higher and may not
It is suitble to all touch screen base materials, such as PET film, while also contains toxic solvents or auxiliary agent.
Therefore, a kind of molding electrically conductive ink of less toxic low-temperature curable how is produced, and uses the electrically conductive ink cloth
