Kev teeb tsa lub chaw kuaj hluav taws xob tsuas yog siv ob peb yam khoom siv thiab cov cuab yeej xwb. Txawm hais tias cov khoom tshwj xeeb ntawm cov khoom siv yuav yog qhov tseem ceeb rau koj daim ntawv thov, cov cuab yeej siv tau zoo ib yam rau yuav luag txhua lub tshuab hluav taws xob.
Multimeter
A multimeter qhov ntsuas qhov yooj yim ua ke nrog nws qhov tseeb thiab qhov tseeb ua rau multimeters yog ib qho cuab yeej siv tau zoo hauv txhua lub tshuab hluav taws xob. Multimeters ntsuas AC thiab DC voltage thiab tam sim no nrog rau kev ua haujlwm. Multimeters feem ntau yog siv los daws teeb meem tsim thiab sim cov qauv qauv. Multimeter accessories muaj xws li transistor test modules, kub sensor probes, high voltage probes, thiab sojntsuam cov khoom siv. Multimeters muaj nyob rau tsawg li $ 10 thiab tuaj yeem khiav ntau txhiab rau qhov raug siab, siab-precision benchtop unit.
LCR Meter
Raws li ntau yam xws li multimeters, lawv tsis tuaj yeem ntsuas qhov capacitance lossis inductance, uas yog qhov chaw inductance, capacitance, thiab qhov ntsuas tsis kam tuaj rau hauv daim duab. LCR meters tuaj nyob rau hauv ob qhov sib txawv-tus nqi qis dua uas ntsuas tag nrho cov impedance ntawm ib feem thiab hom kim dua uas ntsuas tag nrho cov khoom ntawm impedance ntawm cov khoom, sib npaug series kuj, thiab qhov zoo ntawm cov khoom. Qhov tseeb ntawm tus nqi qis LCR meters feem ntau yog qhov tsis zoo, nrog rau siab ntev li 20 feem pua. Txij li thaum muaj ntau lub capacitors muaj 20 feem pua siab ntev rau lawv tus kheej, kev sib xyaw ua ke ntawm cov ntsuas thiab cov khoom ua rau muaj teeb meem ntxiv hauv kev tsim thiab kho cov khoom siv hluav taws xob.
Oscilloscope
Electronics yog txhua yam hais txog cov teeb liab thiab oscilloscope yog lub hauv paus ntsuas cov cuab yeej los soj ntsuam cov duab ntawm cov teeb liab. Oscilloscopes, feem ntau hu ua o-scopes lossis tsuas yog scopes, tso tawm cov cim hauv cov duab nraaj ntawm ib khub ntawm axes, feem ntau nrog Y raws li qhov voltage thiab X raws li lub sijhawm. Hom ntawv no muaj txoj hauv kev muaj zog heev kom nkag siab cov duab ntawm lub teeb liab, txiav txim siab dab tsi tshwm sim hauv hluav taws xob hluav taws xob, thiab saib xyuas nws cov kev ua tau zoo lossis taug qab cov teeb meem. Oscilloscopes muaj nyob rau hauv digital thiab analog variants, pib ntawm ob peb puas duas las thiab khiav mus rau kaum tawm txhiab rau cov qauv saum toj kawg nkaus. Cov scopes muaj ntau yam kev ntsuas thiab kev xaiv ua rau hauv lub cev, uas ua rau kev ntsuas ntawm qhov siab tshaj-rau-nruab nrab voltage, zaus, mem tes dav, nce lub sij hawm, teeb liab sib piv, thiab sau cov waveforms yooj yim cov hauj lwm.
Ntxhais Hlau
Cov cuab yeej tseem ceeb rau kev sib sau cov khoom siv hluav taws xob yog cov hlau nplaum, cov cuab yeej siv tes ua kom cov hlau nplaum los tsim cov hluav taws xob thiab lub cev sib txuas ntawm ob qhov chaw. Soldering irons tuaj nyob rau hauv ob peb daim ntawv, nrog rau pheej yig tshaj plugged ncaj qha mus rau hauv ib lub qhov hluav taws xob los ntawm txhais tes. Thaum cov hlau nplaum no tau ua tiav txoj haujlwm, rau cov khoom siv hluav taws xob feem ntau ua haujlwm qhov chaw tswj qhov kub thiab txias ua haujlwm zoo dua.
Lub taub hau ntawm lub taub hau yog rhuab los ntawm lub qhov cub hluav taws xob thiab feem ntau saib xyuas los ntawm qhov ntsuas kub kom ua kom qhov kub ntawm qhov taub tsis tu ncua. Cov tswv yim hlau soldering feem ntau tshem tau thiab muaj nyob rau hauv ntau yam duab thiab cov qauv kom haum rau ntau hom kev ua haujlwm.
Precision Mechanical Tools
Txhua lub chaw kuaj hluav taws xob xav tau ob peb lub cuab yeej siv tes ua haujlwm tseem ceeb los pab nrog cov haujlwm yooj yim thiab ua kom cov haujlwm nyuaj dua yooj yim dua. Qee cov cuab yeej tseem ceeb suav nrog cov cuab yeej txiav, cov hlau strippers, ESD-kev nyab xeeb tweezers, koob lub qhov ntswg pliers, precision screwdriver set, "thib tes tes" cov cuab yeej, thiab alligator/test clips thiab leads. Qee cov cuab yeej, xws li ESD cov tweezers nyab xeeb, yog qhov tseem ceeb rau kev ua haujlwm saum npoo av thaum lwm cov cuab yeej, xws li "thib peb tes" cov cuab yeej siv tau zoo thaum koj siv cov khoom sib txuas rau lub rooj tsav xwm luam tawm thiab cov khoom siv, PCB, cov hlau nplaum, thiab solder txhua tus yuav tsum tau tuav hauv qhov chaw.
Optics
Cov khoom siv hluav taws xob tau txais me me heev-me me txaus uas lawv tuaj yeem tuav tau yooj yim nrog cov tweezers. Basic lab optics xws li magnifying loupes thiab loj articulated magnifying lo ntsiab muag yog pab tau nyob rau hauv ntau rooj plaub tab sis tsis muab ib tug ntau ntawm magnification, nrog 5x-rau-10x magnification ntawm lub siab tshaj plaws kawg. Loupes thiab magnifying lo ntsiab muag ua haujlwm zoo rau cov kev xav tau hauv chav sim, tab sis yog tias qhov chaw mount lub rooj sib txoos thiab kev soj ntsuam yuav ua tiav, ces lub stereomicroscope yog qhov zoo tagnrho.
Rau qhov chaw mount ua haujlwm, lub stereomicroscope muab nruab nrab ntawm 25x thiab +90x magnification, uas txhawb precision soldering ntawm nto mount chips thiab board-theem soj ntsuam. Stereomicroscopes pib ntawm ib ncig ntawm $ 500 thiab muaj nyob rau hauv qhov ruaj khov lossis sib txawv zoom, ntau yam kev xaiv teeb pom kev zoo, thiab cov kev kho qhov muag ntxiv rau kev teeb tsa lub koob yees duab lossis rau ntau tus neeg siv.
Power Supply
Nws nyuaj rau kev sim lub voj voog yam tsis siv lub zog rau nws. Ntau hom khoom siv hluav taws xob txhawb nqa hluav taws xob tsim thiab kev sim nrog ntau qhov sib txawv ntawm cov yam ntxwv. Rau lub hom phiaj dav dav hauv chav kuaj fais fab, qhov sib txawv voltage-thiab-tam sim no tswj yog ib qho tseem ceeb tshaj plaws. Feem ntau cov khoom siv hluav taws xob no ua haujlwm nyob rau hauv qhov tsis tu ncua-voltage lossis tsis tu ncua-tam sim no, tso cai rau kev sim nrawm ntawm cov khoom lossis feem ntawm cov qauv tsim yam tsis muaj kev tsim hluav taws xob tshwj xeeb Circuit Court.
