Abstract
The invention discloses a technology for stripping metal of a touch screen. A piece of stripping equipment adopts TMAH (developing liquid, tetramethyl ammonium hydroxide) of which the mass ratio is 2.38% as stripping liquid. The metal stripping process is implemented in the stripping equipment by a manner of bearing the touch screen through a small vehicle at speed of 2.0-3.0m/min. The temperature of the stripping liquid is 22-26 DEG C. The light resistance can be effectively removed while the photo-etched metal is stripped by a manner of matching a UV lamp with the TMAH of which the mass ratio is 2.38%, the breakage of the low-temperature metal jumper conductor made of ITO (indium tin oxide) can be reduced, and the product qualification rate can be improved.
Description
Technical field
The present invention relates to touch-screen metal-stripping making technology.
Background technology
At present the touch-screen applications scope has become more and more extensive, and touch-screen is just receiving increasing user and developer's concern as a kind of new human-computer interaction device, and becomes the at present input equipment of the simplest, most convenient.But touch-screen production control processing procedure is the most critical place, metal-stripping processing procedure (Metal stripping) the normal operation NMP (1-METHYLPYRROLIDONE) of photoetching (Photo) gold-tinted processing procedure is as stripper, because principal ingredient is resin in the photoresistance, organic solvent and emulsion, so that the organic stripper solution of composition is very fast to photoresistance dissolving ratio, easily make the PI(insulation course) dilatational strain and attack Metal(metal M O/AL/MO), specifically, photoresistance organic solvent in hard roasting process can volatilize and solidify, but the photoresistance after solidifying still can absorb the NMP organic solvent, and generation dilatational strain, along with soak time increases, photoresistance can progressively be dissolved, and therefore can cause top jump metal (Metal Jumper) to rupture because of change in displacement, form fracture, cause the production qualification rate to reduce.
Summary of the invention
Technical matters to be solved by this invention is to realize that touch-screen can effectively reduce the making technology of jump metal fracture in photoetching metal-stripping processing procedure production run.
To achieve these goals, the technical solution used in the present invention is: a kind of touch-screen metal-stripping making technology, membrane stripping device adopts the TMAH2.38%(developer solution, mass ratio is 2.38% hydroxide four potassium aqueous ammoniums) as stripper spray, and entered by dolly carrying touch-screen and to carry out the metal-stripping processing procedure in the membrane stripping device.
Described membrane stripping device porch is provided with the UV lamp, and lamp shines the photoresist face of the touch-screen that enters peel-off device.
Described UV lamp radiation energy is 500mj/ cm
2, power is 4KW.
Described little vehicle speed is 2.0-3.0m/min., and the stripper temperature is 22-26 ℃.
The invention has the advantages that when using the UV lamp to cooperate the mode of TMAH2.38% to carry out the photoetching metal-stripping, photoresistance effectively can be removed, can reduce the jump metallic conductor fracture of low temperature ITO, improve product percent of pass.
Description of drawings
The below is briefly described the content of every width of cloth accompanying drawing expression in the instructions of the present invention and the mark among the figure:
Fig. 1 is metal-stripping making technology schematic flow sheet;
Fig. 2-5 is that NMP and TMAH2.38% are to the swelling property contrast test linear graph of PI;
Mark among the above-mentioned figure is: 1, peel-off device; 2, UV lamp; 3, ito glass; 4 photoresists.
Embodiment
The touch-screen manufacturing process passes through successively: supplied materials, clean, coating, soft roasting, exposure, develop, hard roasting, etching, stripping, the present invention is mainly for the improvement of final step stripping technique, referring to Fig. 1 as can be known, the stripper NMP of peel-off device 1 is replaced to TMAH2.38%, simultaneously set up UV lamp 2 in the membrane stripping device porch, 4 layers of dolly carrying touch-screen photoresists up, ito glass is towards 3 times, pass this equipment with 2.0-3.0m/min. speed via being provided with UV lamp 2 peel-off devices 1 entrance, TMAH2.38% is evenly sprayed in touch screen surface by the linear mouth spray of peel-off device 1, and wherein UV lamp 2 plays the effect of deteriorated photoresist 4.Preferred 2.5 m/min. of little vehicle speed, preferred 24 ℃ of stripper temperature, UV lamp 2 is take radiation energy as 500mj/ cm
2, best results when power is the 4KW irradiation, residual without photoresistance.
Referring to Fig. 2-5, take to verify the corresponding technological means of feasibility, to NMP and the TMAH2.38% swelling property contrast to PI, peels off with NMP after PI is firmly roasting, peel off processing procedure 1 time after the PI thickness can increase by 6%, along with peeling off the processing procedure increased frequency, thickness reduces gradually, this is very large to jump metal (Metal Jumper) harm, yet uses high concentration TMAH to peel off processing procedure, peel off processing procedure 1 time after the PI thickness almost do not change.
TMAH is organic alkali, and metal is had certain corrosivity, and is larger if long time high concentration is soaked the metal impact, records by experiment, only uses the TMAH stripping 1 time, is subjected to extent of corrosion slighter.After using TMAH2.38% to peel off, the check of finished product touch-screen major light: dirty without stripping, metal particle has certain color distortion, checks under 2D: metal particle has sawtooth or white edge, and metal jumper has white edge, but does not affect outward appearance,
Following table is for using NMP to peel off rear PBT﹠amp; VMI result:
Following table is for using TMAH2.38% to peel off rear PBT﹠amp; VMI result:
To sum up experimental result as can be known, use UV lamp 2 and TMAH2.38% developer solution to replace NMP to peel off, photoresistance effectively can be removed, metal can be attacked by TMAH, white edge or sawtooth situation that 1um is approximately arranged, it is qualified that this is judged to be in the VMI inspection unusually, and PBT splits to have more obviously and improves, and does not find that also the jump metal has the phenomenon of disconnection.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
