Ua ntej, ua kom yuam kev me me rau kev ntsuas ntau yam SMT cov khoom
Qee qhov SMD cov khoom me me thiab tsis yooj yim rau kev sim thiab kho nrog cov cwj mem multimeter zoo tib yam. Ib qho yog tias nws yooj yim los ua kom luv luv Circuit Court, thiab lwm qhov yog tias nws tsis yooj yim rau lub rooj tsav xwm Circuit Court coated nrog cov txheej insulating kom kov cov hlau ntawm cov khoom siv tus pin. Ntawm no yog ib txoj hauv kev yooj yim qhia rau txhua tus, nws yuav coj tau yooj yim heev rau kev kuaj pom.
Siv ob rab koob me me tshaj plaws, (Kev Tswj Kev Tswj Kev Siv Tshuab Sib Nqus Tshuab), kaw lawv rau hauv multimeter cwj mem, tom qab ntawd muab cov hlau nyias nyias los ntawm ntau txoj hlua khi, thiab khi rab koob thiab rab koob rau kev sib koom ua ke, siv cov hlua khi rau. solder khov kho. Nyob rau hauv txoj kev no, tsis muaj kev pheej hmoo ntawm luv luv Circuit Court thaum ntsuas cov SMT Cheebtsam nrog lub xeem cwj mem nrog ib rab koob me me, thiab rab koob taub hau tuaj yeem tho cov txheej txheej insulating thiab ntaus cov khoom tseem ceeb ncaj qha, tsis tas yuav thab rau khawb cov yeeb yaj kiab. .
Thib ob, txoj kev saib xyuas ntawm lub rooj tsav xwm hluav taws xob pej xeem hluav taws xob luv luv Circuit Court txhaum
Hauv kev tu vaj tse hauv Circuit Court, yog tias koj ntsib qhov luv luv ntawm cov khoom siv hluav taws xob rau pej xeem, qhov txhaum feem ntau loj heev, vim tias ntau cov khoom siv tib lub zog sib faib, thiab txhua yam khoom siv hluav taws xob siv hluav taws xob no xav tias yuav luv luv. Yog tias tsis muaj ntau yam ntawm lub rooj tsavxwm, siv "hoe lub ntiaj teb" Tom qab tag nrho, koj tuaj yeem pom qhov luv luv-circuit point. Yog tias muaj ntau yam khoom, nws yuav nyob ntawm txoj hmoo kom "hoe lub ntiaj teb" kom ncav cuag qhov xwm txheej. Ib txoj hauv kev zoo dua raug pom zoo ntawm no. Siv txoj kev no yuav tau txais ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog thiab feem ntau pom qhov txhaum sai sai.
Nws yog ib qho tsim nyog yuav tsum muaj cov khoom siv hluav taws xob nrog kev hloov kho qhov hluav taws xob thiab tam sim no, qhov hluav taws xob 0-30V, tam sim no 0-3A, lub zog hluav taws xob no tsis kim, txog 300 yuan. Kho qhov qhib hluav taws xob hluav taws xob rau cov cuab yeej hluav taws xob hluav taws xob hluav taws xob, ua ntej kho qhov tam sim no kom tsawg, ntxiv qhov hluav taws xob no rau lub zog hluav taws xob hluav taws xob hluav taws xob ntawm lub voj voog, xws li 5V thiab 0V terminals ntawm 74 series nti, nyob ntawm qhov degree ntawm luv luv Circuit Court, maj mam nce tam sim no. Kov lub cuab yeej los ntawm tes. Thaum koj kov ib lub cuab yeej uas ua kom sov heev, qhov no feem ntau yog cov khoom puas, uas tuaj yeem raug tshem tawm rau kev ntsuas ntxiv thiab kev pom zoo. Tau kawg, qhov hluav taws xob yuav tsum tsis pub tshaj qhov ua haujlwm voltage ntawm lub cuab yeej thaum ua haujlwm, thiab kev sib txuas tsis tuaj yeem thim rov qab, txwv tsis pub nws yuav hlawv tawm lwm yam khoom siv zoo.
Peb. Ib tug me me lwv tuaj yeem daws teeb meem loj
Ntau thiab ntau cov laug cam yog siv rau hauv kev lag luam tswj, thiab ntau cov laug cam siv cov ntiv tes kub los ntxig rau hauv cov qhov. Vim yog qhov chaw ua haujlwm hnyav, plua plav, av noo, thiab corrosive gas ib puag ncig, lub rooj tsavxwm yuav muaj kev sib cuag tsis zoo. Cov phooj ywg yuav daws tau qhov teeb meem los ntawm kev hloov lub rooj tsavxwm, tab sis tus nqi ntawm kev yuav lub rooj tsavxwm yog qhov tseem ceeb heev, tshwj xeeb tshaj yog cov laug cam ntawm qee cov khoom siv txawv teb chaws. Qhov tseeb, koj kuj tseem siv tau cov nplaum nplaum los txhuam tus ntiv tes kub ob peb zaug, ntxuav cov av ntawm tus ntiv tes kub, thiab sim lub tshuab dua. Qhov teeb meem yuav daws tau! Txoj kev yog yooj yim thiab siv tau.
Forth. Kev soj ntsuam ntawm cov hluav taws xob tsis zoo hauv lub sijhawm zoo thiab lub sijhawm tsis zoo
Hais txog qhov tshwm sim, ntau yam hluav taws xob tsis zoo nrog lub sijhawm zoo thiab tsis zoo suav nrog cov xwm txheej hauv qab no:
1. Kev sib cuag tsis zoo
Kev sib cuag tsis zoo ntawm lub rooj tsavxwm thiab lub qhov, thaum lub cable tawg sab hauv, nws yuav tsis ua haujlwm, lub ntsaws thiab lub davhlau ya nyob twg tsis sib cuag, thiab cov khoom siv yog soldered.
2. Lub teeb liab cuam tshuam
Rau cov digital circuits, qhov yuam kev tsuas yog tshwm sim hauv qee yam xwm txheej. Nws yog qhov ua tau tias kev cuam tshuam ntau dhau tau cuam tshuam rau kev tswj hwm thiab ua rau muaj kev ua yuam kev. Kuj tseem muaj cov kev hloov pauv ntawm tus kheej cov khoom tsis sib xws lossis kev ua haujlwm tag nrho ntawm lub rooj tsav xwm Circuit Court kom tsis txhob cuam tshuam. Muaj peev xwm nyhav rau qhov tseem ceeb, uas ua rau tsis ua haujlwm;
3. Tsis zoo thermal stability ntawm cov khoom
Los ntawm kev saib xyuas ntau, qhov thermal stability ntawm electrolytic capacitors yog thawj zaug uas tsis zoo, ua raws li lwm cov capacitors, triodes, diodes, ICs, resistors, thiab lwm yam;
4. Cov dej noo thiab plua plav ntawm lub rooj tsav xwm Circuit Court.
Cov dej noo thiab plua plav yuav ua hluav taws xob thiab muaj kev tiv thaiv, thiab tus nqi kuj yuav hloov thaum lub sij hawm thermal expansion thiab contraction. Tus nqi tiv thaiv no yuav muaj qhov cuam tshuam nrog lwm cov khoom. Thaum cov nyhuv no muaj zog, nws yuav hloov qhov tsis sib xws hauv Circuit Court thiab ua rau muaj kev ua haujlwm tsis zoo. tshwm sim;
5. Software kuj yog ib qho kev txiav txim siab
Ntau qhov ntsuas hauv Circuit Court raug kho los ntawm software. Cov npoo ntawm qee qhov ntsuas tau hloov qis dhau thiab nyob rau hauv qhov tseem ceeb. Thaum cov kev ua haujlwm ntawm lub tshuab ua tau raws li cov laj thawj ntawm cov software los txiav txim qhov tsis ua haujlwm, ces lub tswb yuav tshwm sim.
Thib tsib, yuav ua li cas kom sai nrhiav cov ntaub ntawv tivthaiv
Cov khoom siv hluav taws xob niaj hnub no muaj ntau haiv neeg, thiab cov khoom ntawm cov khoom siv tau ua ntau thiab ntau yam. Hauv kev tu vaj tse, tshwj xeeb tshaj yog nyob rau hauv kev lag luam kev lag luam Circuit Court board tu, ntau yam tsis pom lossis tsis hnov tsw ntawm. Tsis tas li ntawd, txawm tias cov ntaub ntawv ntawm cov khoom ntawm ib lub rooj tsavxwm ua tiav, Tab sis yog tias koj xav xauj thiab txheeb xyuas cov ntaub ntawv no ib qho los ntawm ib qho hauv koj lub computer, yog tias tsis muaj txoj kev tshawb nrhiav ceev, kev saib xyuas yuav raug txo kom tsawg. Hauv kev lag luam hauv kev lag luam hluav taws xob, kev ua haujlwm yog nyiaj, thiab kev ua haujlwm zoo ib yam li cov nyiaj hauv hnab tshos.
