Kev tsim cov txheej txheem ntawm cov ntawv qhia cov av noo suav nrog ntau cov kauj ruam tseem ceeb. Cov tub ntxhais yog cov txheej txheem meej ntawm cov dej noo-sensing cov ntaub ntawv mus rau ib lub substrate, ua raws li cov txheej txheem tom ntej los tsim ib daim ntawv qhia uas qhia meej cov av noo hloov. Tam sim no, cov txheej txheem tseem ceeb tau hloov pauv los ntawm cobalt- cov khoom siv rau ib puag ncig tus phooj ywg cobalt- cov ntaub ntawv pub dawb kom tau raws li EU RoHS thiab lwm yam kev cai ib puag ncig.
Cov txheej txheem kev tsim khoom tseem ceeb ntws
Kev Npaj Substrate: Cov ntawv nqus tau zoo heev (xws li cov ntawv ntoo ntoo) yog siv los ua cov substrate kom ntseeg tau tias cov dej tsis sib haum ntawm cov dej noo - hnov cov tshuaj thiab cov lus teb sai rau cov av noo.
Moisture-Sensing Material Coating: Cov txheej txheem dej tau npaj-sensing tov (xws li cobalt-dawb compound lossis cobalt chloride tov) yog dotted los yog luam tawm mus rau qhov chaw uas siv lub tshuab txheej. Cov txheej txheem no yuav tsum tau tswj cov txheej thickness thiab uniformity ntawm kev faib tawm kom ntseeg tau cov xim rhiab heev thiab sib xws.
Kev ziab thiab kho: Cov ntawv coated yog muab tso rau hauv qhov cub kom qhuav thiab ziab ntawm 40-60℃kom ruaj khov thiab kho cov txheej, tiv thaiv smudging los yog tsis ua hauj lwm thaum thauj thiab khaws cia.
Slitting thiab Forming: Cov nplooj ntawv loj ntawm cov khoom raug txiav rau hauv qhov ntau thiab tsawg (piv txwv li, credit card loj). Qee cov khoom lag luam muaj cov kab sib npaug los tiv thaiv khawb ntawm cov khoom sab hauv.
Kev soj ntsuam zoo: Ib qho colorimeter yog siv los xyuas seb qhov kev hloov xim ntawm txhua qhov taw qhia ua tau raws li qhov kev teeb tsa (piv txwv li, 5%, 10%, 60% RH), kom ntseeg tau tias cov xim hloov pauv tau meej meej thiab ua raws li cov qauv kev lag luam xws li JEDEC J-STD-033 thiab MILAI-8.
Ntim thiab Cia: Cov khoom tiav tau muab ntim rau hauv cov hnab ntawv aluminium lossis cov kaus poom hlau nrog cov desiccant ntxiv los tiv thaiv kom tsis txhob muaj xim tsis zoo vim ya raws thaum khaws cia. Kev ntim khoom ib txwm yog 100 nplooj ntawv ib lub kaus poom, nrog ntau lub kaus poom ntim rau hauv ib lub thawv.
