Dab tsi yuav tsum tau them sai sai rau thaum siv LCD npo:
1. Lub vijtsam LCD yuav tsum tiv thaiv kom tsis txhob raug tsav los ntawm DC voltage. Qhov me me ntawm DC tivthaiv ntawm qhov voltage, qhov zoo dua. Tsis txhob ntau tshaj 50mV. Kev siv lub sijhawm ntev ntawm cov khoom siv DC ntau dhau yuav ua rau electrolysis thiab electrode aging, uas yuav txo tau lub neej.
2. Cov kua siv lead ua kua yuav tsum tau tiv thaiv los ntawm cov hluav taws xob ultraviolet: cov kua siv lead ua kua thiab cov polarizers yog cov organic, thiab cov tshuaj photochemical thiab degradation yuav tshwm sim nyob rau hauv ultraviolet hluav taws xob. Yog li ntawd, thaum cov khoom siv ua kua siv lead ua tau sib sau ua ke, nws yuav tsum tau txiav txim siab seb nws puas tsim nyog rau nruab ib lub cuab yeej tiv thaiv rau pem hauv ntej raws li nws lub hom phiaj thiab ib puag ncig siv. UV lim lossis lwm txoj kev tiv thaiv UV. Tsis txhob siv lub hnub ci ncaj qha mus ntev thaum siv nws.
LCD
3. Cov kua siv lead ua kua yuav tsum muaj kev tiv thaiv los ntawm corrosion ntawm cov pa phem: cov kua siv lead ua kua thiab cov polarizers yog cov organic thiab chemically reacted thiab deteriorated nyob rau hauv ib puag ncig ntawm cov pa phem. Yog li ntawd, kev ntsuas cais rau cov pa phem yuav tsum tau siv. Tsis tas li ntawd, tom qab tag nrho lub tshuab tau sib sau ua ke, Tsis txhob nqa lub sijhawm ntev kaw kom tsis txhob muaj cov pa roj ntau dhau los ntawm cov yas casing thiab Circuit Court board tu tus neeg saib xyuas los ntawm kev puas tsuaj rau cov kua siv lead ua kua thiab polarizer.
4. Cov khoom siv ua kua siv lead ua kua yog ua los ntawm ob daim iav, tsuas yog 5 ~ 10um ntawm lawv, uas yog nyias heev. Ntxiv mus, sab hauv ntawm lub iav yog coated nrog ib txheej ntawm oriented zaj duab xis, uas yog ib qho yooj yim rau kev puas tsuaj. Yog li ntawd, cov ntsiab lus hauv qab no kuj yuav tsum tau sau tseg: Tsis txhob siv lub zog ntau dhau ntawm cov khoom siv ua kua siv lead ua kom tsis txhob muaj kev puas tsuaj rau txheej txheej. Nyob rau hauv cov ntaub ntawv ntawm lub siab dhau los yog tes-nias ntawm lub cuab yeej thaum lub sij hawm sib dhos txheej txheem, nws yuav tsum tau tso cai rau sawv ntsug rau ib teev ua ntej qhib lub hwj chim. Nco ntsoov tsis txhob muaj qhov kub thiab txias hloov thaum lub sijhawm ua haujlwm ntawm lub hwj chim. Lub siab yuav tsum yog txawm tias thaum txhim kho, tsuas yog nias sab ntawm lub cuab yeej, tsis yog nruab nrab, lossis qaij thiab quab yuam.
5. Vim tias cov kua siv lead ua kua hauv lub xeev yuav ploj mus yog tias nws dhau ntawm qhov kub thiab txias, nws yuav tsum tau muab khaws cia thiab siv nyob rau hauv qhov ntsuas kub. Yog tias qhov kub thiab txias dhau lawm, cov kua siv lead ua kua hauv lub xeev yuav ploj mus thiab ua kua, cov duab saum npoo yuav dub, thiab nws yuav tsis ua haujlwm. Thov ceev faj tsis txhob siv fais fab rau lub sijhawm no, thiab nws tuaj yeem rov qab los ntawm nws tus kheej tom qab qhov kub thiab txias. Yog tias qhov ntsuas kub qis dhau, cov kua siv lead ua kua pib khov, ua rau muaj kev puas tsuaj mus tas li. Tsis tas li ntawd, yog tias khaws cia ntawm qhov kub thiab txias rau lub sijhawm ntev lossis raug kev co lossis kev poob siab, lub LCD kuj tseem yuav tsim cov npuas.
6. Tiv thaiv iav tawg: Txij li cov khoom siv iav yog ua los ntawm iav, yog tias nws ploj lawm, lub iav yuav tawg tiag tiag. Yog li ntawd, txoj kev sib dhos thiab kev co thiab kev cuam tshuam ntawm kev sib dhos yuav tsum tau txiav txim siab thaum lub tshuab tag nrho tsim.
7. Cov khoom pov thawj noo noo: Vim qhov tsis tshua muaj hluav taws xob thiab lub zog siv hluav taws xob tsawg ntawm cov khoom siv ua kua siv lead ua kua, qhov kev tiv thaiv ntawm cov khoom siv lead ua kua yog siab heev (txog 1X1010Ω). Yog li ntawd, vim hais tias ntawm cov iav nto los ntawm ya raws, qhov tshwm sim ntawm "stringing" ntawm cov ntu yuav tshwm sim thaum lub cuab yeej tso tawm, yog li kev tsim ntawm tag nrho lub tshuab yuav tsum xav txog kev ya raws. Nyob rau lub sijhawm ib txwm, sim muab tso rau ntawm qhov kub ntawm 5-30 degree thiab av noo ntawm 65 feem pua.
8. Kev tuav thiab ntxuav cov khoom siv ua kua siv lead ua kua: Txij li cov khoom siv lead ua kua yog ua los ntawm cov yas polarizers thiab cov reflectors, nws yog mos thiab yooj yim rau khawb, yog li ceev faj thaum tuav thiab sib sau ua ke los tiv thaiv LCD los ntawm kev sib tsoo ntawm txhua qhov. lwm yam thiab ua rau cov iav tawg Thiab khawb, kom cov neeg ua haujlwm tuaj yeem ntxuav cov iav tawg thiab lwm cov khib nyiab ntawm cov txee hauv lub sijhawm. Lub vijtsam LCD muaj cov yeeb yaj kiab tiv thaiv ntawm lub polarizer ua ntej tawm hauv lub Hoobkas, thiab nws raug tshem tawm ua ntej sib dhos cov khoom. Yog tias tsis muaj pob tshab tiv thaiv npog ntawm qhov chaw ntawm lub vijtsam LCD ntawm cov khoom tiav, cov yeeb yaj kiab tiv thaiv yuav tsum tau muab tso rau ntawm qhov screen.
Thaum muaj impurities nyob rau saum npoo ntawm lub vijtsam LCD, koj tuaj yeem tshuab nws ua ntej. Yog tias nws tsis tuaj yeem tshuab tau, siv cov ntaub mos mos, ntaub tsis muaj plua plav lossis paj rwb los so nws maj mam. Yog tias koj yuav tsum siv cov kuab tshuaj los ntxuav, koj tsuas tuaj yeem siv isopropanol (glycerin), cawv, thiab Freon, tab sis tsis yog dej, acetone, lossis cov kuab tshuaj tsw qab xws li toluene, txwv tsis pub cov polarizer ntawm lub tshuab yuav puas. Yog tias cov tee dej nyob ntawm lub LCD module tau ntev, nws yuav ua rau tsis muaj xim los yog stains, yog li nco ntsoov ntxuav nws hauv lub sijhawm.
9. Yog tias nws yog cov kua siv lead ua kua nrog cov hlau pins, thaum soldering cov pins, cov pob qij txha yuav tsum yog 4 hli los yog ntau tshaj ntawm cov hauv paus hniav, thiab lawv yuav tsum tsis txhob raug quab yuam los yog overheating kom tsis txhob muaj kev puas tsuaj rau kev sib txuas. Kub kub: 280 ± 10 degree Vuam lub sij hawm:<3 s; soldering="" material:="" eutectic,="" low="" melting="" point;="" repeated="" soldering="" shall="" not="" exceed="" 3="">
Cov ntsiab lus saum toj no yog kev qhia txog yam koj yuav tsum tau them sai sai rau thaum siv cov ntxaij vab tshaus LCD. Tsis tas li ntawd, nws raug txwv tsis pub siv cov kuab tshuaj organic xws li cawv, lossis daim ntaub ntxhib lossis ntawv, vim tias cov tshuaj no nquag khawb thiab cuam tshuam rau cov zaub. nyhuv. Tsis tas li yuav tsum tau ceev faj tsis txhob tsuag tus neeg saib xyuas ncaj qha rau ntawm qhov chaw ntawm lub vijtsam LCD, kom tus neeg saib xyuas tuaj yeem yooj yim ntws mus rau hauv lub vijtsam, ua rau luv luv hauv lub vijtsam LCD thiab ua rau lub tshuab puas.
