Yog li kuv muaj lub ntsuas pokit (https://pokitmeter.com/) tab sis cov hlau lead tau ua puas, kuv tus tub tau ua rau lawv sib tw hauv cov txheej txheem rub tawm. Tu siab Pokitmeter tsis txaus siab muab cov khoom seem, tab sis kuv tau teeb tsa qhov ntsuas qhov ntsuas ib txwm tsis tu ncua.
Qhib lub pokit meter qub yog qhov yooj yim yooj yim, thaum tshem tawm lub roj teeb, lub pob tshab sab nrauv npog qhib. Sab hauv yog cov ntu koj pom saum toj no. Cov hlau lead raug kaw thiab muab tso rau ntawm PCB.
Kauj Ruam 1: Tshem Cov Thawj Coj Qub
Siv me me, ntse, ntswj ntswj kom ua tib zoo muab khoom plig tuav cov xim liab thiab dub qhib me ntsis. Ceev faj tsis txhob plam thiab desolder ib qho ntawm cov khoom me me saum npoo, lossis kho qhov no tsuas yog nyuaj dua.
Tam sim no thov cov hlau txuas rau cov clamps thiab rub ib qho ntawm cov coj mus deb. Rov ua dua rau lwm cov hlau lead.
Kauj Ruam 2: Cuam Tshuam ntawm Cov Thawj Coj Tshiab
Txiav cov txiv tsawb ntsaws tawm ntawm cov coj qub*.
Muab cov xov hlau tso nrog lub raj kub me ntsis.
Muab cov hlau lead coj los khi rau ntawm pcb, nco ntsoov kom liab thiab dub yog txoj kev nyob ib puag ncig kom koj lub 'meter' nyeem qhov zoo thiab tsis raug rau txoj kev yog, thaum kho.
Pinch lub clamps kaw kom muab qee yam nyem nyem.
*Nws ib txwm them kom tso 2-3cm ntawm cov hmoov txhuas uas koj txiav tawm, yog li koj tuaj yeem khaws lawv, thiab tej zaum txuas lawv mus rau lwm yam uas koj yuav tsim yav tom ntej. Yog tias koj txiav lawv ze rau cov ntsaws koj yuav tsum muab pov tseg, vim koj yuav tsis tuaj yeem koom nrog ib yam dab tsi rau lawv tom qab.
Kauj Ruam 3: Hloov Kho Tus Neeg Rho Tawm Yog tias Koj Cov Thawj Coj Loj Tshaj Li Cov Thawj
Tam sim no koj tuaj yeem pib rov sib sau ua ke. Yog tias koj cov thawj coj yog thawj tus tsuas yog muab nws rov qab ua ke thaum nws sib nrug. Tam sim no koj ua tiav.
Yog tsis yog…
Koj yuav tsum tau hloov kho qhov no yog tias koj cov kab tshiab coj los puag lossis muaj cov rwb thaiv tsev me me ntau dua li cov thawj coj uas tau tiaj thiab nqaim kom haum rau hauv lub tshuab nqus tsev. Kuv lees tias yuav tsis muaj kev thim cov thawj coj tam sim no.
Kuv txiav cov yas me me los ntawm ntu no tso cai rau txoj hauv kev tawm ntawm lub tsev.
Tam sim no koj tuaj yeem txuas cov yas dawb rau hauv pcb, nco ntsoov npog me me rau cov kab fuse nrog cov tooj liab rau lub fuse ntawm pcb.
Kauj Ruam 4: Hloov Kho Sab Nrauv Sab Nrauv Sab Nrauv
Thaum koj tau ntsia ob lub ntsej muag dawb (thiab cov ntsia hlau me me tuav rov qab) nyob ib puag ncig koj lub pcb, koj tuaj yeem xa qhov no mus rau ib nrab ntawm sab nraud ntawm cov ntaub ntawv sab nraud, lub caij nplooj ntoo hlav rov qab haum rau hauv qhov, hauv ib nrab ntawm sab nraud rooj plaub. Tsis txhob tso cua nruj rau nws, vim qhov no tsis yog cov cuab yeej siv rov qab tau.
Kev sib tw haum rau ib nrab ntawm sab nrauv ntawm rooj plaub pcb sib dhos. Muaj feem yuav yog cov coj tshiab yuav tsis haum los ntawm qhov nqaim nqes nyob rau ib nrab ntawm cov ntaub ntawv sab nrauv. Yog li txiav me ntsis ntawm nws tam sim ntawd, zoo li hauv daim duab. Kuv siv cov hlau txiav me me los txiav qee cov duab peb sab. Xyuas kom lawv du kom lawv tsis txhob abrade koj rwb thaiv tsev tom qab. Tsis tas li, nco ntsoov tias koj sim ua kom haum rau ib nrab ntawm cov ntaub ntawv sab nrauv, tom qab ntawd kos qhov chaw uas koj xav tau txiav tawm, vim tias cov coj tsuas yog tshwm sim hauv ob qho chaw thiab cov no raug kho, koj yuav tsum txiav tawm thaj chaw raug.
Kauj Ruam 5: Rov Kho Tus Kheej Li Cas
Cov ntaub ntawv tseem ceeb snaps ua ke. Tom qab ntawd lub fuse tuaj yeem haum. Nws tsuas yog ua haujlwm nrog cov blobs ntawm lub ntsej muag tig rov qab, thiab tom qab ntawd tsuas yog tias nws yog txoj hauv kev ib puag ncig. Yog tias nws tsis ua haujlwm tig nws sab qaum teb mus rau sab qab teb thiab sim dua.
Cov hlau zoo li lub ntsej muag thiab lub caij nplooj ntoo hlav me me uas tuav lub khawm khawm rov qab tam sim no yog cov khoom seem.
Haum lub roj teeb, ua kom lub zog muaj zog thiab sim nws.
