Nyob rau hauv cov txheej txheem ntawm kev kho lub xov tooj ntawm tes, cov ntawv ci tooj liab ntawm lub rooj tsav xwm Circuit Court feem ntau tev
tawm. Cov laj thawj yog raws li nram no. Ua ntej, cov neeg ua haujlwm saib xyuas feem ntau ntsib cov ntawv ci tooj liab
strips vim tsis siv technology los yog txoj kev tsis raug thaum tshuab cov khoom los yog
integrated circuits. Qhov thib ob, ib feem ntawm lub xov tooj ntawm tes uas tau corroded los ntawm kev poob
dej, thaum ntxuav nrog lub tshuab ntxhua khaub ncaws ultrasonic, ib feem ntawm cov ntawv ci tooj liab ntawm lub voj voog
board yog ntxuav tawm. Hauv qhov no, ntau tus kws kho mob tsis muaj kev xaiv tab sis txiav txim rau lub xov tooj ntawm tes
xov tooj li "tuag". Yog li yuav ua li cas thiaj li rov qab tau cov ntawv ci tooj liab txuas?
1. Nrhiav cov ntaub ntawv sib piv
Txheeb xyuas cov ntaub ntawv kev saib xyuas cuam tshuam kom pom qhov twg cov khoom siv tus pin txuas nrog
pin qhov twg daim ntawv tooj liab yog tev tawm. Thaum pom, txuas ob tus pins nrog enameled
hlau. Vim tias tam sim no txoj kev loj hlob sai ntawm cov qauv tshiab, cov ntaub ntawv txij nkawm yog lagging,
thiab cov ntaub ntawv kho ntawm ntau lub xov tooj ntawm tes yog qhov yuam kev ntau dua, thiab muaj qee yam
qhov sib txawv piv nrog cov khoom tiag tiag, yog li txoj kev no tsuas yog siv rau kev siv xwb
daim ntawv thov.
2. Nrhiav nrog ib tug multimeter
Thaum tsis muaj cov ntaub ntawv, koj tuaj yeem siv multimeter los nrhiav nws. Txoj kev yog: siv lub digital
multimeter, muab cov ntaub ntawv tso rau ntawm lub buzzer (feem ntau yog cov ntaub ntawv diode), siv ib tus cwj mem los kov
tooj liab ntawv ci tawm pins, thiab lwm yam xeem cwj mem kom txav tus so ntawm tus pins ntawm lub
Circuit Board. Thaum koj hnov ib lub suab nrov, tus pin uas ua rau lub suab nrov txuas nrog tus pin
qhov twg daim ntawv tooj liab poob. Lub sijhawm no, koj tuaj yeem siv qhov ntev ntawm qhov tsim nyog
enameled hlau thiab txuas nws ntawm ob tus pins.
3. Reweld
Yog tias ob txoj hauv kev saum toj no tsis raug, nws muaj peev xwm ua rau ko taw khoob. Tab sis yog nws yog
tsis npliag, thiab koj tsis tuaj yeem paub tias cov khoom siv twg yog txuas nrog cov ntawv ci tooj liab
kev tso tawm, koj tuaj yeem siv cov hniav los maj mam txhuam cov ntawv ci tooj liab tawm ntawm lub rooj tsavxwm.
Tom qab scraping tawm cov ntawv tshiab tooj liab, siv cov hlau soldering ntxiv Tin maj mam ua rau
pins tawm thiab solders lawv mus rau lub desoldered pins.
4. Txoj kev sib piv
Raws li qhov xwm txheej, nws yog qhov zoo dua los nrhiav ib lub rooj tsav xwm hauv Circuit Court ntawm tib yam li qub
tshuab rau kev sib piv, ntsuas qhov kev sib txuas ntawm qhov sib thooj ntawm qhov
ib txwm siv lub tshuab, thiab tom qab ntawd sib piv cov ntawv ci tooj liab uas tau poob vim qhov kev sib txuas
ua tsis tiav.
Nws yuav tsum raug sau tseg tias thaum sib txuas, nws yuav tsum paub qhov txawv ntawm qhov txuas
ib feem yog xov tooj cua zaus circuit lossis logic circuit. Feem ntau hais lus, yog lub logic
Circuit Court raug txiav thiab tsis txuas, nws yuav ua rau muaj kev phiv, thiab RF feem
kev sib txuas yuav feem ntau muaj kev phiv. Lub teeb liab zaus ntawm Circuit Court yog kuj
siab. Tom qab ib txoj kab txuas nrog, nws qhov kev faib tawm tsis muaj kev cuam tshuam ntau dua.
Yog li ntawd, nws feem ntau tsis yooj yim rau kev sib txuas hauv xov tooj cua zaus. Txawm tias nws
yog kev cob cog rua, nws yuav tsum luv li sai tau.
