Txoj Kev 1: Saib ua ntej thiab ntsuas tom qab Siv cov cuab yeej: multimeter, magnifying iav
Thaum tuav lub rooj tsav xwm Circuit Court ntawm lub tshuab txhaj tshuaj molding yuav tsum tau kho, nws yog ib tug cwj pwm zoo uas yuav tsum xub xyuas nws qhov muag pom, thiab siv lub iav tsom iav yog tias tsim nyog. Koj pom dab tsi?
Feem ntau saib:
1. Txawm tias muaj kev cuam tshuam;
2. Discrete Cheebtsam xws li resistors, electrolytic capacitors, inductors, diodes, triodes, thiab lwm yam yog disconnected;
3. Txawm hais tias cov ntawv luam tawm Circuit Board txuas kab ntawm lub rooj tsavxwm ntawm lub tshuab txhaj tshuaj molding puas tawg lossis daig;
4. Puas muaj leej twg kho nws? Yam khoom twg tau txav mus los? Txawm hais tias muaj kev ua haujlwm yuam kev xws li kev siv lub tshuab virtual, tsis muaj vuam, thiab thim rov qab;
Tom qab paub meej tias cov khoom yuav tsum tau kho tsis muaj cov xwm txheej saum toj no, ua ntej siv lub multimeter los ntsuas qhov kev tiv thaiv ntawm lub hwj chim thiab hauv av ntawm lub tshuab txhaj tshuaj molding tshuab Circuit Board. Yog tias qhov kev tiv thaiv tsawg dhau, tsuas yog ob peb lossis kaum ohms, nws txhais tau hais tias muaj ib qho Yog tias cov khoom tawg tau tawg lossis ib nrab tawg, kev ntsuas yuav tsum tau ua kom pom cov khoom tawg.
Txoj kev tshwj xeeb yog muab lub zog rau lub rooj tsav xwm Circuit Court kom kho, thiab kov qhov kub ntawm cov khoom ntawm lub rooj tsavxwm Circuit Court ntawm lub tshuab txhaj tshuaj molding nrog koj txhais tes. Cov kub yuav yog cov neeg raug liam tseem ceeb. Yog hais tias tus nqi kuj yog ib txwm, siv ib tug multimeter los ntsuas discrete Cheebtsam xws li resistors, diodes, transistors, teb nyhuv transistors, thiab dial keyboards ntawm lub rooj tsavxwm. Lub hom phiaj yog ua ntej kom ntseeg tau tias cov khoom ntsuas tau zoo li qub. Peb qhov laj thawj yog vim li cas peb tuaj yeem siv multimeter daws qhov teeb meem, tsis txhob ua rau nws nyuaj.
Txoj Kev 2: Ua ntej sab nraud thiab tom qab ntawd sab hauv
Cov cuab yeej siv: Circuit Court txij nkawm ntsuas ntsuas
Yog tias qhov xwm txheej tso cai, nws yog qhov zoo tshaj plaws los nrhiav ib lub rooj tsavxwm zoo uas zoo ib yam li lub rooj tsavxwm raug kho raws li kev siv, thiab tom qab ntawd siv dual-bar VI nkhaus scanning muaj nuj nqi los sib piv qhov zoo thiab qhov tsis zoo ntawm ob lub rooj tsavxwm. Qhov kev sib piv thawj zaug tuaj yeem pib los ntawm qhov chaw nres nkoj, thiab tom qab ntawd los ntawm qhov chaw mus rau sab hauv, tshwj xeeb tshaj yog qhov kev sib piv ntawm kev sib piv, tuaj yeem ua rau qhov tsis txaus uas lub multimeter nyuaj los ntsuas seb puas muaj cov xau hauv online.
Txoj Kev 3: Thawj qhov yooj yim thiab tom qab ntawd nyuaj
Cov cuab yeej siv: Circuit Court txij nkawm ntsuas ntsuas, hluav taws xob soldering hlau, cwj mem
Txhawm rau txhim kho cov txiaj ntsig kev xeem, ua ntej kev sim online ua haujlwm ntawm lub rooj tsavxwm ntawm lub tshuab txhaj tshuaj molding, qee qhov kev ua haujlwm yuav tsum tau ua rau ntawm lub rooj tsavxwm kho kom txo tau qhov tsis zoo ntawm ntau yam cuam tshuam ntawm cov txheej txheem xeem. Cov kev ntsuas tshwj xeeb yog:
1. Kev npaj ua ntej kev xeem
Short-circuit siv lead ua oscillator, thiab solder ib ceg ntawm lub loj electrolytic capacitor kom nws qhib, vim hais tias lub them thiab tawm ntawm lub capacitor kuj yuav ua rau muaj kev cuam tshuam.
2. Siv txoj kev cais tawm los kuaj lub cuab yeej
Thaum lub sijhawm kuaj online lossis sib piv ntawm cov khoom siv, thov ncaj qha lees paub qhov kev xeem rau cov khoom siv uas dhau qhov kev xeem (lossis kuj yog ib txwm muaj) rau kev kaw; yog tias qhov kev xeem tsis ua tiav (lossis tsis kam lees), koj tuaj yeem sim nws dua. Yog tias koj dhau, koj tuaj yeem lees paub qhov kev xeem ua ntej, thiab txuas ntxiv kev sim zoo li no kom txog thaum cov khoom siv ntawm lub rooj tsavxwm raug kuaj (lossis muab piv), thiab rov qab mus rau cov khoom siv uas ua tsis tau qhov kev xeem (lossis kuj tawm ntawm kam rau ua).
Rau cov khoom siv uas ua tsis tau qhov kev sim ua haujlwm hauv online, qhov ntsuas kuj tseem muab txoj kev kho tsis zoo tab sis siv tau ntau dua. Txij li thaum lub hwj chim ntawm lub twj tso kua mis mus rau lub rooj tsavxwm Circuit Court ntawm lub tshuab txhaj tshuaj molding tuaj yeem siv rau cov khoom siv hluav taws xob sib txuas thiab tus pin hauv av ntawm cov cuab yeej los ntawm kev sim clip, yog tias txiav lub hwj chim tus pin ntawm lub cuab yeej nrog ib rab riam, thiab cov cuab yeej siv. yuav raug cais tawm ntawm lub hwj huam mov ntawm lub rooj tsav xwm Circuit Court ntawm lub tshuab txhaj tshuaj molding. Lub sijhawm no, kev sim ua haujlwm hauv online ntawm lub cuab yeej yuav ua tiav. Cov nyhuv yog sib npaug rau "quasi-offline", thiab qhov tseeb tus nqi yuav zoo dua.
3. Siv ASA-VI nkhaus scan test los sib piv thiab sim cov cuab yeej uas tsis tau them los ntawm lub tsev qiv ntawv xeem
Vim tias ASA-VI ntse nkhaus scanning thev naus laus zis tuaj yeem siv rau qhov kev sib piv ntawm ib qho khoom siv, tsuav yog qhov kev sim clip tuaj yeem clamp lub cuab yeej, thiab muaj lub rooj tsav xwm siv, los ntawm kev sib piv, cov cuab yeej kuj muaj qhov ua txhaum loj. muaj peev xwm nrhiav tau. Qhov kev ua haujlwm no ua rau qhov tsis txaus ntseeg tias qhov kev sim ua haujlwm hauv online ntawm lub cuab yeej yog nyob rau hauv lub tsev qiv ntawv xeem, thiab nthuav dav qhov kev tshawb nrhiav ntau yam ntawm cov cuab yeej rau lub Circuit Court board tsis ua haujlwm ntawm lub tshuab txhaj tshuaj molding.
Hauv kev muaj tiag, nws feem ntau tshwm sim tias lub rooj tsav xwm zoo tsis tuaj yeem pom raws li kev siv, thiab cov qauv ntawm lub rooj tsavxwm yuav tsum tau kho tsis muaj qhov sib luag. Hauv qhov no, ASA-VI nkhaus scanning kev sib piv kev xeem ua haujlwm tsis ua haujlwm, thiab kev sim ua haujlwm hauv online Vim lub tsev qiv ntawv ntsuas cov khoom tsis tiav, nws tsis tuaj yeem kuaj txhua yam ntawm lub rooj tsavxwm ntawm lub tshuab txhaj tshuaj molding, thiab lub Circuit Court. board ntawm lub tshuab txhaj tshuaj molding tseem tsis tuaj yeem kho. Qhov no yog qhov txwv ntawm Circuit Court txij nkawm ntsuas ntsuas, ib yam li tsis muaj kev kho rau txhua yam kab mob. .
Txoj Kev 4: Ua ntsiag to ua ntej tsiv mus
Txij li thaum lub ntsuas hluav taws xob hauv online tsuas tuaj yeem ua qhov kev sim hauv online thiab kev soj ntsuam zoo li qub ntawm cov khoom hauv Circuit Court board ntawm lub tshuab txhaj tshuaj molding tam sim no, seb nws puas kho tag nrho lossis tsis yuav tsum tau kuaj los ntawm tag nrho lub tshuab. Yog li ntawd, nws yog qhov zoo tshaj plaws los xyuas seb lub hwj chim ntawm cov khoom puas raug muab rau lub rooj tsav xwm Circuit Court ntawm lub tshuab txhaj tshuaj molding raws li qhov yuav tsum tau ua.
