Cov kua siv lead ua kua module yog cov khoom siv uas sib sau ua ke cov khoom siv ua kua siv lead ua kua, lub LCD maub los, lub voj voog tsav, thiab lub rooj tsav xwm PCB ua ke. Nws tuaj yeem txuas ncaj qha rau lub computer. Thaum siv hom qauv no, ntxiv rau lub vijtsam LCD dav dav, cov khoom hauv qab no yuav tsum raug sau tseg thaum sib dhos thiab siv:
1. Kov cov yeeb yaj kiab tiv thaiv
Muaj cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ua tiav cov kua siv lead ua kua uas tau teeb tsa los tiv thaiv nws qhov chaw los ntawm kev sib kis thaum sib dhos. Nws tsis tuaj yeem raug tshem tawm ua ntej tag nrho lub tshuab tau sib sau ua ke kom tsis txhob muaj staining lossis staining ntawm cov zaub.
2. Ntxiv padding
Nws yog qhov zoo dua rau nruab ib lub gasket txog 0.1 hli nruab nrab ntawm lub module thiab lub vaj huam sib luag pem hauv ntej. Lub vaj huam sib luag yuav tsum nyob twj ywm kiag li. Nco ntsoov tias tsis muaj lub zog sib tw yog tsim tom qab sib dhos. Thiab txhim kho kev ua haujlwm seismic.
3. nruj me ntsis tiv thaiv hluav taws xob zoo li qub
Kev tswj thiab tsav Circuit Court nyob rau hauv cov kua siv lead ua kua zaub module yog ib qho kev txhawb zog micro-voltage, tsawg-voltage CMOS Circuit Court, nws yog ib qho yooj yim raug ntaus los ntawm hluav taws xob zoo li qub, thiab tib neeg lub cev qee zaum tsim hluav taws xob hluav taws xob zoo li qub siab li ob peb volts. los yog ntau pua volts, yog li Peb yuav tsum tau ceev faj heev hauv kev ua haujlwm, sib dhos thiab siv, thiab peb yuav tsum nruj me ntsis tiv thaiv hluav taws xob zoo li qub. Vim li no: 1) Tsis txhob kov cov hlau lead sab nraud, lub voj voog ntawm lub rooj tsav xwm Circuit Court thiab cov ncej kub ntawm tes.
2) Yog tias tsim nyog los ua kev sib cuag ncaj qha, tib neeg lub cev thiab cov qauv yuav tsum tau khaws cia ntawm tib lub peev xwm, lossis tib neeg lub cev yuav tsum tau txuas nrog hauv av. 3) Cov hlau nplaum uas siv thaum vuam yuav tsum tau ua kom zoo hauv av kom ntseeg tau tias nws tsis muaj qhov hluav taws xob.
4) Qee qhov kev khiav hauj lwm hluav taws xob thiab lwm yam cuab yeej yuav tsum tau ua kom zoo hauv av kom ntseeg tau tias tsis muaj qhov xau.
5) Tsis txhob siv lub tshuab nqus tsev ntxhua khaub ncaws. Vim tias lub tshuab nqus tsev vacuum tuaj yeem tsim hluav taws xob zoo li qub.
6)) Thaum huab cua qhuav heev, hluav taws xob zoo li qub kuj raug tsim tawm. Yog li, cov av noo hauv chav ua haujlwm yuav tsum siab dua RH60%.
7) Kev tiv thaiv kev tiv thaiv yuav tsum tau tsim nyob nruab nrab ntawm hauv av, cov rooj zaum, lub laub, workbenches, rhawv thiab cov cuab yeej kom muaj peev xwm zoo ib yam, txwv tsis pub hluav taws xob zoo li qub kuj tseem raug tsim.
8) Thaum tshem tawm los yog muab rov qab rau hauv lub hnab ntim khoom lossis hloov txoj haujlwm, koj yuav tsum tau ceev faj ntxiv kom tsis txhob muaj hluav taws xob zoo li qub. Tsis txhob hloov lossis pov tseg cov khoom ntim thawj ntawm qhov xav tau.
9) Electrostatic tawg yog ib hom kev puas tsuaj uas tsis tuaj yeem kho, yog li yuav tsum ua tib zoo saib xyuas nws, tsis txhob siv nws. 4. Qee qhov kev ceev faj thaum txhim kho cov xyab thiab txav mulberry.
Cov modules tau ua tib zoo tsim thiab sib sau ua ke los ntawm cov neeg, thov tsis txhob arbitrarily txheej txheem thiab sib sau ua ke. 1) Lub claws ntawm cov ncej kub yuav tsum tsis txhob twisted thiab disassembled ntawm lub siab nyiam.
2) Tsis txhob' t arbitrarily hloov cov duab, Circuit Court, sib dhos qhov L thiab cov khoom ntawm cov txheej txheem PCB board. 3) Nws tsis tuaj yeem hloov daim kab xev conductive.
4) Thov tsis txhob hloov kho ib qho khoom siv sab hauv.
5) Tsis txhob' kov, tswj, khoov lossis ntswj nws cov qauv. 5. Vuam
Thaum welding sab nraud thiab interface circuits ntawm lub module, cov txheej txheem hauv qab no yuav tsum tau ua. 1) Qhov kub ntawm cov hlau taub hau yuav tsum tsawg dua 280 ° C
2) Lub sijhawm vuam yuav tsum tsawg dua 3-4 teev. 3) Cov khoom siv vuam: eutectic, qis melting point. 4) Don' tsis siv cov kua qaub.
5) Sim tsis txhob rov ua dua qhov vuam ntau dua peb zaug, thiab txhua qhov rov ua dua yuav tsum muaj sijhawm li 5 feeb. 6. Kev siv thiab tu cov pwm acetylene
1) Thaum lub module siv los txuas thiab tshem tawm cov khoom siv hluav taws xob, nws yuav tsum tau nqa tawm raws li lub sijhawm teev qhia hauv daim duab. Ntawd yog: nws yuav tsum tau tawm tswv yim los ntawm qhov zoo fais fab mov (5 ± 0.25V) ua ntej lub teeb liab voltage tuaj yeem nkag. Yog hais tias lub teeb liab voltage yog input ua ntej lub hwj chim yog stably txuas los yog tom qab nws yog disconnected, lub integrated circuit nyob rau hauv lub module yuav puas thiab module yuav puas.

2 Dot matrix module yog ib tug high-channel tooj liab LCD zaub, uas muaj kev sib raug zoo nrog cov duab sib piv, saib lub kaum sab xis, kub thiab tsav voltage. Yog li ntawd, Vee yuav tsum tau kho kom zoo tshaj qhov sib piv thiab saib lub kaum sab xis. Yog tias Vee raug kho siab dhau lawm, nws yuav tsis tsuas cuam tshuam rau cov zaub, tab sis kuj cuam tshuam rau lub neej ntev ntawm cov khoom siv.
3) Thaum siv nyob rau hauv qis qis ntawm qhov ntsuas kub ntawm kev ua haujlwm, cov lus teb yuav qeeb heev. Thiab thaum siv nyob rau hauv qhov kev khiav hauj lwm kub ntau yam, tag nrho cov zaub interface yuav ncaj qha tig dub, uas tsis yog kev puas tsuaj. Tom qab qhov ntsuas kub tau rov qab los, nws tuaj yeem rov qab los li qub.
4) Nias nyuaj rau ntawm qhov pom yuav ua rau muaj qhov txawv txav. Tsuav yog peb txiav tawm lub hwj huam mov thiab rov txuas nws, nws yuav rov qab los.
5) Thaum condensation tshwm sim nyob rau saum npoo ntawm cov kua siv lead ua kua los yog cov pwm, tsis txhob ua hauj lwm nrog hluav taws xob, vim hais tias qhov no yuav ua rau cov tshuaj tiv thaiv ntawm cov electrode thiab tawg cov hlau. 6) Thaum siv rau lub sijhawm ntev nyob rau hauv tshav ntuj thiab lub teeb muaj zog, qhov ntxoov ntxoo tuaj yeem tsim cov duab seem.
7. Cia ntawm LCD module
Rau kev khaws cia ntev (xws li ntau xyoo lossis ntau dua), peb tuaj yeem pom zoo rau cov hauv qab no. 1) Muab tso rau hauv ib lub hnab polyethylene (nyiam dua nrog cov tshuaj tiv thaiv zoo li qub), thiab kaw lub qhov ncauj. 2) Khaws ntawm -10 ° C thiab +35 ° C.
3) Khaws cia rau hauv qhov chaw tsaus thiab tsis txhob muaj lub teeb muaj zog.
4) Tsis txhob tso dab tsi rau saum npoo.
5) nruj me ntsis txwv tsis pub cia nyob rau hauv huab cua kub / av noo, xws li cia nyob rau hauv tshwj xeeb tej yam kev mob, nws tseem yuav khaws cia ntawm 40 ° C, 85% RH, los yog 60 ° C. Tsawg dua 60% RH, tab sis nws yuav tsum tsis pub tshaj 168 teev.
