1. Kev ceev faj ua haujlwm:
1. Lub vijtsam zaub yog ua los ntawm iav, thov tsis txhob siv lub tshuab ua kom poob siab, xws li ntog los ntawm qhov chaw siab.
2. Yog hais tias cov zaub puas lawm thiab cov kua siv lead ua kua sab hauv, tsis txhob cia nws nkag mus rau hauv lub qhov ncauj. Yog tias nws nkag rau hauv khaub ncaws lossis tawv nqaij, ntxuav nws sai sai nrog xab npum thiab dej.
3. Tsis txhob siv lub zog ntau dhau rau qhov chaw tso saib lossis thaj chaw sib txuas ntawm LCD module, vim qhov no yuav ua rau lub suab xim hloov.
4. Lub polarizer rau ntawm qhov chaw ntawm LCD module zaub screen yog mos thiab yooj yim rau khawb. Thov ua tib zoo saib xyuas.
5. Yog hais tias qhov chaw ntawm lub LCD module zaub screen yog qias neeg, so nws nrog ib tug mos qhuav ntaub. Yog hais tias nws yog stains heev, so nws nrog isopropyl cawv los yog ethanol (cawv), dampened nrog ib daim ntaub.
6. Lwm cov kuab tshuaj yuav ua rau cov polarizer puas tsuaj, tshwj xeeb tshaj yog dej, ketones, tshuaj tsw qab, thiab lwm yam.
7. Thaum siv lub mounting qhov rau nruab lub LCD module, xyuas kom meej tias nws tsis yog twisted, khoov los yog deformed. Deformation tuaj yeem ua rau muaj kev cuam tshuam loj rau cov khoom zoo.
8. Thaum txhim kho lub LCD module, tsis txhob yuam kom rub lossis khoov I / O coj los yog lub teeb nraub qaum.
9. Kov TAB ntawm LCD module yuav ua rau cov zaub tsis zoo. Tsis txhob kov TAB.
10. Tsis txhob disassemble lub LCD module.
11. Lub NC tus pin yuav tsum qhib sab laug thiab tsis txuas nrog dab tsi.
12. Yog hais tias lub hwj chim ntawm lub logic Circuit Court raug txiav tawm, tsis txhob tso lub teeb liab.
13. Txhawm rau tiv thaiv electrostatic kev puas tsuaj rau cov khoom siv, tuav lub chaw ua haujlwm zoo.
ib. Thaum tuav lub module, tsis txhob muab tso rau hauv av.
b. Sib dhos cov cuab yeej, xws li cov hlau soldering, yuav tsum tau muab tso rau hauv av kom zoo.
c. Txhawm rau txo qhov tsim hluav taws xob zoo li qub, tsis txhob ua kev sib dhos thiab lwm yam haujlwm hauv qhov chaw qhuav.
d. Lub LCD module muaj txheej txheej ntawm zaj duab xis los tiv thaiv lub vijtsam. Ceev faj thaum tshem cov yeeb yaj kiab tiv thaiv no, vim tias hluav taws xob zoo li qub yuav raug tsim tawm.
14. Tsis txhob qhib lub voj voog, thiab ceev faj txog kev ua haujlwm ntawm cov ntawv kub-sealing.
15. Lub ntug ntawm lub iav screen yog ntse, tuav nws kom zoo.
2. Kev ceev faj cia
Thaum khaws cov LCD module, tsis txhob raug tshav ntuj ncaj qha los yog lub teeb fluorescent. Khaws lub LCD module nyob rau hauv ib lub hnab anti-static, thiab muab cia rau hauv chav tsev kub thiab av noo. (Tsis txhob muaj cov av noo / siab kub thiab kub qis dua 0 degree .) Yog tias ua tau, LCD module yuav tsum tau muab cia rau hauv cov xwm txheej thaum xa los ntawm peb lub tuam txhab.
Peb, lwm yam
1. Ntawm qhov kub thiab txias (hauv qab qhov ntsuas kub ntawm qhov ntsuas), qhov ua kom khov ntawm cov kua siv lead ua kua yuav ua rau cov kev taw qhia tsis xws luag lossis ua npuas (dub lossis dawb). Cov npuas huab cua kuj tsim tau thaum cov kua siv lead ua kua module yog vibrated muaj zog ntawm qhov kub thiab txias.
2. Yog hais tias lub LCD module ua haujlwm ntev thiab qhia tib tus qauv, tus qauv yuav nyob twj ywm ntawm qhov screen zoo li phantom thiab yuav muaj qhov sib txawv me me. Yog tias koj xav rov ua haujlwm zoo li qub, koj tuaj yeem tso tseg tsis siv nws ib ntus. Nws yog tsim nyog sau cia tias qhov tshwm sim no yuav tsis muaj kev cuam tshuam tsis zoo rau kev ntseeg siab ntawm kev ua haujlwm.
Cov lus qhia rau kev siv LCD
1. Cov kua siv lead ua kua (LCD) yuav tsum tiv thaiv DC tivthaiv ntawm kev tsav tsheb los ntawm kev siv lub DC voltage tsawg li sai tau. 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 (LCD) yuav tsum muaj kev tiv thaiv los ntawm cov hluav taws xob ultraviolet: cov kua siv lead ua kua thiab cov polarizers yog cov organic, thiab cov tshuaj tiv thaiv photochemical thiab degradation yuav tshwm sim nyob rau hauv ultraviolet hluav taws xob. Yog li ntawd, thaum sib sau ua ke cov kua siv lead ua kua zaub, xav txog seb nws puas yuav tsum tau nruab rau hauv pem hauv ntej raws li nws lub hom phiaj thiab kev siv ib puag ncig. Anti-ultraviolet lim los yog lwm txoj kev los tiv thaiv ultraviolet. Tsis txhob siv lub hnub ci ncaj qha mus ntev thaum siv nws.
3. Cov kua siv lead ua kua (LCD) 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 teeb meem gases, yog li cov teeb meem roj cais yuav tsum tau noj thaum siv lawv, thiab tom qab tag nrho lub tshuab tau sib sau ua ke, Tsis txhob nqa cov ntim ntim rau lub sijhawm ntev los tiv thaiv cov khoom siv tshuaj lom neeg ntau dhau los ntawm cov yas casing thiab Circuit Court board ntxuav 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. Txij li cov kua siv lead ua kua hauv lub xeev yuav ploj mus dhau qhov kub thiab txias, nws yuav tsum tau khaws cia thiab siv nyob rau hauv qhov ntsuas kub ntawm 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 raug txiav txim siab thaum lub sij hawm tsim ntawm tag nrho lub tshuab.
7. Cov ntaub ntawv pov thawj ntawm cov khoom siv: Vim yog qhov tsis tshua muaj hluav taws xob thiab 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 (saum toj no 1X1010Ω). Yog li ntawd, qhov conductivity ntawm iav nto los ntawm noo noo tuaj yeem ua rau qhov tshwm sim ntawm "stringing" ntawm ntu thaum lub cuab yeej tso tawm. Yog li ntawd, tus tsim ntawm tag nrho cov tshuab yuav tsum xav txog cov dej-pov thawj. 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 kho mob ntawm cov kua siv lead ua kua zaub: Txij li cov kua siv lead ua kua yog ua los ntawm cov yas polarizer thiab reflector, khawb thiab stains yuav tsum zam thaum sib dhos thiab khaws cia. Tsis tas li ntawd, muaj ib qho kev tiv thaiv zaj duab xis rau pem hauv ntej polarizer, uas tau muab tshem tawm thaum siv. Yog tias qhov chaw ntawm lub cuab yeej muaj kab mob, nws tuaj yeem kho nrog cov ntaub mos mos lossis paj rwb. Yog tias koj yuav tsum siv cov kuab tshuaj los ntxuav, koj tsuas tuaj yeem siv isopropanol (glycerin), cawv, freon, thiab tsis txhob siv acetone, aromatic solvents, xws li toluene, thiab lwm yam., txwv tsis pub cov polarizer ntawm qhov chaw ntawm lub cuab yeej yuav puas.
9. Yog tias nws yog LCD nrog cov hlau pins, thaum soldering 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. Qhov siab tshaj plaws kub tsis kam ntawm qhov sib koom ua ke yuav tsum tsis pub tshaj 80 degree. Tsis txhob siv xab npum los ntxuav cov pins, vim tias cov tshuaj ntxuav tes yuav decompose chlorine nyob rau hauv tshav ntuj thiab tsim hydrochloric acid tom qab nqus dej, uas yuav corrode electrode.
