LCD module yog ib yam khoom tseem ceeb heev hauv peb lub neej, yog li koj puas paub dab tsi yog cov teeb meem uas yuav tsum tau them sai sai rau thaum tsim cov qauv ntawm cov khoom siv ntawm LCD module? Nov yog cov lus qhia ntxaws:
1. Lub LCD module muaj cov kev cai siab. Thaum debugging thiab txhim kho, nws yog ib qho tsim nyog kom tsis txhob muaj kev cuam tshuam sab nraud.
2. Tsis txhob cuam tshuam nrog ib qho kev tawm tsam ntawm lub rooj tsav xwm hauv Circuit Court thiab hlau thav duab, tsuas yog zam kom nws tsim nyog.
3. Nco ntsoov tias lwm yam khoom siv yuav tsum tsis txhob kov cov khoom siv lossis cov pob qij txha ntawm lub LCD module PCB kom tsis txhob muaj kev cuam tshuam luv luv.
4. Tsis txhob kov cov roj hmab conductive nrog cov kua siv lead ua kua uas muaj cov nplaum nplaum nplaum. Kev sib cuag me ntsis tuaj yeem ua rau cov nplaum nplaum nplaum hloov pauv.
5. Thaum txhim kho lub LCD module, xyuas kom meej tias PCB tsis deformed vim twisting los yog lwm yam quab yuam los tiv thaiv lub sab hauv tooj liab hlau ntawm lub Circuit Court board los ntawm kev tawg mus ntev.
6. Tsis txhob nias cov hlau taw rau ntawm qhov chaw thiab sab nraub qaum ntawm cov ncej hlau, uas tuaj yeem ua rau cov khoom siv roj hmab ua kom deform thiab plam kev sib cuag, ua rau tsis muaj khawb. Cov hlau thav duab tsim los ntawm Nanjing Rohm LCD yog tag nrho cov thickened thiab tiv thaiv stainless hlau hlau ncej. , tuaj yeem ua kom ruaj khov siv sijhawm ntev.
7. Cov hluav taws xob zoo li qub. Txij li thaum lub LCD module muaj precision chips thiab circuits, kev ntsuas yuav tsum tau ua kom tsis txhob muaj hluav taws xob zoo li qub, xws li hnav khaub ncaws los tiv thaiv zoo li qub, hnav ib txoj hlua electrostatic, hnav cov ntiv tes cots, thiab lwm yam.
8. Vuam, tsuas yog rau I / O terminals. Tsuas yog siv cov hlau nplaum uas tsim nyog hauv av thiab tsis muaj qhov xau tam sim no. Siv cov hlau tsis kub kub nrog cov khoom siv sab hauv. Yog tias koj siv flux, koj yuav tsum npog lub ntsej muag ntawm cov kua siv lead ua kua kom tiv thaiv cov flux los ntawm kev txaws, thiab tom qab ntawd tshem cov flux residue.
9. Vuam kub: 280°C+10°C
10. Lub sijhawm vuam: 3-4 vib nas this.
11. Vaj huam sib luag ntxuav dej, peb feem ntau ntsib cov neeg muas zaub uas yuam kev infiltrate lub vaj huam sib luag ntxuav dej rau hauv lub LCD npo thaum ntxuav, ua rau tsis ua hauj lwm ntawm cov conductive strips thiab cov scrapping ntawm lub backlight board. Yog li, nws raug pom zoo tias LCD module yog soldered, thiab lub vaj huam sib luag ntxuav dej yuav tsum tsis txhob siv ntau li ntau tau. Rau kev ntxuav, tin dross tuaj yeem raug tshem tawm kom tsis txhob muaj qhov tshwm sim saum toj no.
