Description
Technical field
The present invention relates to touch screen technology field, more particularly to a kind of novel touch screen low temperature manufacturing process.
Background technology
Touch-screen is a kind of input equipment for significantly improving man machine operation interface, is had the advantages that directly perceived, simple, quick.
Touch-screen has been obtained for being widely applied in many electronic products, for example smart mobile phone, PDA, multimedia, public information are looked into
Inquiry system etc..
In traditional process for manufacturing touch panel, conductive silver paste solidification temperature used can just be fully cured more than 130 DEG C.
Therefore need substrate membrane material by least 150 DEG C, 1 it is small when more than burin-in process process, can ensure in follow-up silver paste
In curing process, substrate membrane material is not in that deformation, fold, harmomegathus etc. are abnormal.
And time-consuming for burin-in process process, more than the 30% of whole touch-screen manufacturing time is accounted for；Efficiency is low, easily because of waiting
Substrate membrane material carries out burin-in process and causes the idle material of producing line, shut-down, high energy consumption, adds the energy loss in production process；Process
Numerous and diverse, easily the scuffing of base substrate, folding line etc. are abnormal caused by operating reason in operation.
Therefore, if burin-in process process can be reduced, the production efficiency of touch-screen can be greatly improved, reduce production energy
Consumption, shortens manufacturing step, improves product yield.
