Hauv kev tshawb nrhiav ntawm PCB thim rov qab thev naus laus zis, thim rov qab daim duab kab lus hais txog kev thim rov qab ntawm PCB daim duab duab lossis PCB daim duab kos duab kos ncaj qha raws li lub cev lub cev ntawm cov khoom, txhawm rau piav qhia lub hauv paus ntsiab lus thiab lub xeev ua haujlwm ntawm pawg thawj coj saib xyuas. Ib qho ntxiv, daim duab qhia chaw tseem siv los tshuaj xyuas cov yam ntxwv ua haujlwm ntawm cov khoom nws tus kheej. Hauv kev tsim ua ntej, kev tsim khoom dav dav yuav tsum xub ua cov qauv tsim, thiab tom qab ntawd ua tiav PCB tsim raws li cov qauv tsim.

Cov txheej txheem PCB muaj lub luag haujlwm tshwj xeeb, txawm hais tias nws tau siv los tshuaj xyuas cov hauv paus ntsiab lus ntawm Circuit Court thiab cov yam ntxwv khoom lag luam hauv kev kawm thim rov qab, lossis raws li lub hauv paus thiab lub hauv paus ntawm PCB tsim hauv kev tsim qauv. Yog li, yuav ua li cas thim rov qab PCB cov txheej txheem, thiab cov ntsiab lus dab tsi yuav tsum rov ua cov txheej txheem them nyiaj rau, raws li cov ntaub ntawv lossis yam tiag?

1. Tsim nyog faib thaj chaw ua haujlwm

Thaum daim duab qhia chaw ntawm PCB pawg thawj coj tau hloov pauv, qhov tsim nyog faib ua haujlwm ntawm thaj chaw tuaj yeem pab cov kws kho tsheb txo cov teeb meem tsis tsim nyog thiab txhim kho kev kos duab zoo.Feem ntau, cov khoom siv nrog tib lub luag haujlwm ntawm PCB yuav raug teeb tsa hauv lub hauv paus, thiab thaj chaw ua haujlwm tau tuaj yeem muaj lub hauv paus yooj yim thiab raug yog thaum cov phiaj xwm tau thim rov qab. Txawm li cas los xij, kev faib ntawm thaj chaw ua haujlwm no tsis yog qhov xav tau. Nws xav kom cov kws tsim txuj ci kom nkag siab txog kev paub txog hluav taws xob hauv xov tooj cua. Ua ntej, tshawb xyuas cov khoom tseem ceeb hauv chav ua haujlwm, thiab tom qab ntawd raws li qhov txuas txuas, nrhiav lwm yam khoom siv ntawm tib lub chaw ua haujlwm, thiab tsim kev faib ua haujlwm. Kev tsim cov kev faib ua haujlwm yog lub hauv paus ntawm cov txheej txheem. Tsis tas li, tsis txhob hnov ​​qab siv cov lej lej ntawm lub rooj tsavxwm thaum lub sijhawm txheej txheem, uas tuaj yeem pab koj faib ua haujlwm tau sai dua.

2. Nrhiav cov cim

Qhov kev siv no tseem tuaj yeem hais tias yog lub hauv paus tseem ceeb ntawm PCB daim ntawv theej ntawm qhov pib ntawm kev kos duab. Tom qab cov npe siv tau txheeb xyuas, kos raws li cov pins ntawm cov ntu siv no tuaj yeem ua kom raug qhov tseeb ntawm daim duab qhia chaw kom ntau dua. Kev txiav txim siab ntawm ntu siv tsis yog qhov teeb meem nyuaj rau cov kws tsim khoom. Feem ntau, cov khoom siv uas ua lub luag haujlwm tseem ceeb hauv Circuit Court tuaj yeem raug xaiv ua cov khoom siv. Lawv feem ntau loj thiab muaj ntau tus pin, uas yooj yim rau ncab. Xws li kev sib xyaw ua ke, hloov pauv, transistors, thiab lwm yam, tuaj yeem ua raws li qhov tsim nyog siv.

3, kom paub qhov txawv kab, kab tsim nyog

Txhawm rau kom paub qhov txawv hauv av, lub zog thiab kab teeb liab, cov kws tsim khoom kuj tseem yuav tsum muaj kev paub txog kev siv hluav taws xob, kev txuas hluav taws xob, PCB thaiv thiab lwm yam. Qhov sib txawv ntawm cov xov hluav taws xob no tuaj yeem tshuaj xyuas los ntawm kev sib txuas ntawm cov khoom sib txuas, qhov dav ntawm cov ntawv tooj liab hauv kab hluav taws xob, thiab cov yam ntxwv ntawm cov khoom siv hluav taws xob lawv tus kheej. Hauv daim duab qhia kab, cov xov hlau hauv av tuaj yeem siv ntau tus cim hauv av kom tsis txhob hla thiab cov kab tawg. Cov kab tuaj yeem pom qhov sib txawv los ntawm kev siv kab sib txawv hauv cov xim sib txawv, thiab cov cim tshwj xeeb tuaj yeem siv rau ntau yam khoom siv, thiab txawm tias cov khoom siv hluav taws xob tuaj yeem kos tus kheej thiab thaum kawg ua ke.

4. Xib fwb cov hauv paus ntsiab lus thiab xa mus rau cov duab kos zoo sib xws

Rau qee qhov txheej txheem hluav taws xob hluav taws xob yooj yim thiab cov hauv paus ntsiab lus kev kos duab, cov kws tshaj lij yuav tsum tau ua tus tswv, tsis yog kom ncaj qha kos cov hauv paus yooj yim ntawm qee qhov yooj yim thiab cov khoom siv hluav taws xob ib txwm muaj, tab sis kuj suav tag nrho cov txheej txheem ntawm hluav taws xob hluav taws xob. Ntawm qhov tod tes, tsis txhob quav ntsej cov khoom siv hluav taws xob zoo sib xws hauv PCB daim phiaj phiaj xwm kab kos duab muaj qee qhov zoo sib xws. Cov kws tshaj lij tuaj yeem siv tag nrho cov txheej txheem zoo sib xws los ua qhov rov qab ntawm cov khoom lag luam tshiab raws li kev paub.

5. Tshawb xyuas thiab ua kom zoo dua qub

Tom qab ua tiav cov txheej txheem, koj yuav tsum thim rov qab tsim cov txheej txheem PCB los ntawm kev sim thiab txheeb xyuas qhov txuas. Lub npe qhov tseem ceeb ntawm cov khoom siv cuam tshuam rau PCB kev faib khoom yuav tsum tau tshuaj xyuas thiab ua kom zoo dua. Raws li PCB cov ntaub ntawv teeb duab, cov duab kos sib piv thiab tshuaj xyuas kom ntseeg tau tias cov duab kos yog zoo ib yam nkaus li cov duab kos. Yog tias cov txheej txheem txheej txheem pom tsis ua tau raws li qhov yuav tsum tau ua thaum kuaj xyuas, cov txheej txheem yuav raug kho kom txog thaum nws tsim nyog, tus qauv, raug thiab meej.
