Lub tshuab ntim khoom sib xyaw ua ke ntsuas kev ntsuas, lub ntsiab yuav tsum ntsuas cov ntsiab lus tseem ceeb.
Txoj kev dav dav yog siv cov cuab yeej ntsuas txhua qhov taw qhia qhov hluav taws xob thiab tus pin rau hauv av tsis kam, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kev siv hluav taws xob thiab cov khoom siv hluav taws xob / tso zis waveform, thiab cov txiaj ntsig kev xeem sib piv nrog cov kev sib xyaw ua ke hauv ib puag ncig, tuaj yeem txiav txim siab qhov sib xyaw ua ke kom kuaj tau. ib txwm.
hauv
ntim tshuab, feem ntau siv integrated circuit microprocessors, tuab zaj duab xis integrated circuit thiab hloov fais fab mov ua hauj lwm amplifier IC.
Cia peb piav qhia ntxaws txog cov no.
packing tshuab integrated circuit testing nyob rau hauv qhov tseem ceeb ntawm cov ntsiab lus ntsuas kev sib txuas hauv Circuit Court.
1.
Tus yuam sij rau microprocessor integrated circuit test point
tus yuam sij rau microprocessor integrated circuit test point yog tsuas yog VDD fais fab mov sab, RESET, RESET, siv lead ua IN vibration teeb liab input, Xor siv lead ua vibration teeb liab tso tawm kawg ntawm cov tswv yim, tso zis, thiab lwm yam circuits.
Kev ntsuas online ntsuas qhov tseem ceeb ntawm qhov tsis kam thiab tus nqi hluav taws xob thiab ib txwm tuaj yeem txiav txim siab qhov sib xyaw ua ke yog qhov qub;
2.
Tus yuam sij ntawm qhov hloov hluav taws xob hloov hluav taws xob IC xeem point
Tus yuam sij rau lub zog hloov hluav taws xob IC xeem taw tes yog feem ntau Vc nrhiav kom pom cov tswv yim kawg, qhov hluav taws xob, qhov ntsuas tam sim no, cov zis hluav taws xob, thiab lwm yam.
Kev sim hauv online tau siv los ntsuas qhov sib xyaw ua ke ntawm qhov hluav taws xob thiab qhov tsis kam ntawm txhua tus pin, thiab tom qab ntawd muab piv nrog cov ntaub ntawv ntawm ib txwm muaj, xws li qhov sib txawv loj, yuav tsum tau kuaj cov khoom sib txuas, cov khoom siv yog txiav txim siab nyob rau hauv cov xwm txheej ntawm ib txwm muaj, tuaj yeem txiav txim siab. integrated circuit tau puas lawm.
Nyob rau hauv lub hloov integrated Circuit Court hloov raj yog lub ntsiab tivthaiv, lub built-in tuab zaj duab xis integrated Circuit Court ntawm loj fais fab hloov raj thaum nws tsis zoo rau kev tsis ntseeg hloov raj yuav ntsuas los ntawm switching tube c, b, e heev ntawm pem hauv ntej thiab thim rov qab. mus rau kev txiav txim.
3.
Qhov tseem ceeb ua haujlwm amplifier IC test point
tus yuam sij ntawm kev ua haujlwm amplifier IC xeem point feem ntau yog cov tswv yim thiab cov zis.
Qhov no point ntawm static voltage tus nqi yog siab dua.
kuaj, lub multimeter rau dc voltage, ntsuas qhov tso zis voltage tus nqi ntawm qhov kawg thiab tsis zoo fais fab mov kawg.
Nrog tes hlau tweezers, nyob rau hauv lem, tapping ob lub tswv yim kawg ntawm lub lag luam amplifier (
Koom nrog lub teeb liab jamming)
, thiab saib lub moos oscillation qhov xwm txheej, ib txwm, multimeter pointer yuav muaj oscillation loj dua, xws li pointer tsis txav, ces lub lag luam amplifier tau puas lawm.
4.
Fais tsheb kauj vab tshwj xeeb integrated circuit point test.
nyob rau hauv lub ntim tshuab, feem ntau siv 555 lub sij hawm puag integrated circuit TL494 Circuit Court thiab Circuit Court.
Cia peb saib tshwj xeeb ntawm cov ntsiab lus tseem ceeb ntawm cov kev sim tshwj xeeb (
1)
Kev txiav txim siab ntawm kev sib koom ua ke Circuit Court T494
packing tshuab integrated circuit test rau kev txiav txim siab ntawm kev sib txuas ntawm T494 hauv cov kauj ruam raws li hauv qab no.
1)
Npaj ntsuas.
Kev ntsuas kev sib xyaw ua ke los xaiv ntau lub zog, xws li digital multimeter, qauv nrog MY68 hom tswv yim thiab MS820 hom digital multimeter.
Lawv tuaj yeem ntes cov zaus ntawm 150 KHZ thiab 200 KHZ.
Kuj xav tau ib lub oscilloscope, adjustable kuj hlau winding, thiab lwm yam.
2)
Oscillation zaus ntsuas.
Thawj ntsia hlau multimeter rau 200 KHZ, qhov kev tshawb fawb ua ntej T494 oscillation tus nqi (
Ntawm lwm yam kev sib xyaw ua ke xws li hauv qab 200 hz, tuaj yeem kho lub iav)
, nyob rau hauv thiaj li yuav raug.
T494 oscillation nyob rau hauv 5, thiab 6 ko taw, yog li lub multimeter cwjmem thiab nyob rau hauv ob txhais taw, lawv muaj peev xwm txiav txim seb lub sawtooth yoj.
Charger thiab tswj Circuit Court ntawm oscillation zaus ntawm 20 ~ 80 kh, qhov kev txiav txim tau ntawm tej yam muaj nuj nqis, lub integrated circuit oscillation yog ib txwm, kuj capacitance tus nqi yog lawm.
Yog tias tsis muaj cov cim qhia ntawm oscillation, yuav tsum xyuas qhov chaw tiv tauj thiab cwj mem thiab, xaim, thiab lwm yam.
Yog tias rov ntsuas dua yog qhov tsawg dua qhov ntsuas tus lej ntawm kev sib xyaw ua ke muaj teeb meem.
yog tias qhov zaus tsis tso cai, qhia rau Rr lossis Cr, pom qhov xwm txheej tsim nyog hloov kho lossis hloov.
3)
Ntsuas lub luag haujlwm piv.
Npaj rau oscilloscope, yuav T494 tso zis tus pin 9, 10, txuas lub input interface ntawm oscillograph, thiab nce mus rau 9, 10 ko taw thiab rated load.
Ntawm no nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis muaj kev ntsuas load, lub luag hauj lwm piv tsis yog qhov tseeb ntsuas, deviates los ntawm tus nqi ntawm tus thawj tsim.
Saib xyuas oscilloscope 9, 10 feet ntawm cov zis waveform, tib lub sij hawm kho cov dej num piv: los tswj cov khoom, kho qhov ceev regulating kov, los ntawm 0 spin;
Lub charger, kho tus nqi kuj ntawm 0 mus rau 6 ko taw (
Lub capacitance C, tib lub sijhawm kho)
.
Lub sijhawm no los ntawm oscilloscope yuav tsum pom lub luag haujlwm hloov pauv ntawm xoom mus rau ib puas feem pua.
packing tshuab integrated circuit yog ib txwm los yog tsis muaj feem xyuam rau lub tshuab tuaj yeem ua haujlwm li qub, yog li nws yog ib qho tseem ceeb, Kuv vam tias tsab xov xwm no packing tshuab integrated circuit test yuav pab tau rau koj.
