Yuav ua li cas xaiv qhov zoo nti inductor rau SMT nti ua?
1. Tag nrho qhov dav ntawm cov nti inductor yuav tsum qis dua qhov dav dav ntawm inductor kom tsis txhob muaj cov khoom siv ntau dhau los ntawm kev ua kom muaj zog tensile ntau dhau los hloov tus nqi inductor thaum cov dej txias.
2. Qhov tseeb ntawm cov nti inductors muaj nyob rau hauv kev muag khoom lag luam feem ntau yog ± 10%. Yog tias qhov tseeb siab dua ± 5%, koj yuav tsum xaj kom ntxov.
3. Qee cov nti inductors tuaj yeem welded los ntawm reflow qhov cub thiab yoj soldering, tab sis kuj tseem muaj qee cov nti inductors uas tsis tuaj yeem welded los ntawm yoj soldering.
4. Thaum overhauling, nws tsis tuaj yeem hloov lub inductor nrog lub nti inductor tsuas yog los ntawm tus nqi ntawm inductor. Txhawm rau kom paub meej cov yam ntxwv ua haujlwm, nws tseem yuav tsum nkag siab txog kev ua haujlwm zaus ntawm cov nti inductors.
5. Cov qauv tsim thiab kev qhia tshwj xeeb ntawm cov nti inductors zoo sib xws, thiab cov qauv tsim tsis muaj qhov cim tseem ceeb. Thaum xuas tes ua los yog xuas tes ua, koj yuav tsum tau ceev faj heev thiab tsis txhob ua yuam kev lossis khaws cov khoom tsis raug.
6. Nyob rau theem no, muaj peb hom chip inductors: thawj hom, high-frequency inductors rau microwave cua sov. Muaj feem xyuam rau kev siv ntau zaus nyob ib ncig ntawm 1GHz. Qhov thib ob yog high-frequency nti inductors. Nws yog tsim rau series resonance tswj Circuit Court thiab zaus xaiv fais fab mov Circuit Court. Qhov thib peb yog cov tswv yim inductors. Feem ntau siv tau rau lub zog hluav taws xob ntawm kaum ntawm megahertz.
7. Cov khoom sib txawv siv cov kab sib txawv ntawm cov hlau nplaum sib nqus. Txawm hais tias tib tus nqi ntawm inductor siv, qhov ntsuas kev tiv thaiv pom tsis zoo ib yam. Nyob rau hauv lub high-frequency tswj voj, kev ntsuas kuj yog heev teeb meem rau tus nqi Q, yog li xyuam xim rau nws thaum tsim lub tswv yim.
8. Nws raug tso cai los ua tus nqi ntsuas ntawm cov nti inductance raws li qhov loj ntawm tam sim no. Thaum lub hwj huam mov Circuit Court yuav tsum tau lub luag hauj lwm rau qhov loj npaum li cas ntawm tam sim no, qhov Performance index tus nqi ntawm lub capacitor yuav tsum tau muab coj los xav.
9. Thaum lub hwj chim inductors siv nyob rau hauv DC / DC converters, qhov loj ntawm lawv inductors tam sim ntawd cuam tshuam rau tus cwj pwm ua hauj lwm ntawm lub hwj chim Circuit Court. Raws li qhov teeb meem tiag tiag, txoj kev kho cov hlau nplaum feem ntau tuaj yeem siv los hloov cov inductors kom ua tiav cov txiaj ntsig.
10. Hlau-qhov txhab inductors muaj nyob rau hauv cov khoom siv sib txuas lus ua haujlwm nyob rau hauv ntau zaus ntawm 150 ~ 900MHz. Nyob rau hauv lub zaus fais fab Circuit Court nyob ib ncig ntawm 1GHz, microwave cua kub zaus inductors yuav tsum tau siv. Thaum tus neeg siv khoom siv smt thaj hom, tau kawg, nws kuj tau teev tseg hauv ntau yam. Tsuas yog cov neeg ua haujlwm tuaj yeem lees paub tias nws tau koom ua ke tiag tiag rau hauv kev muag khoom tom qab txiav txim siab tag nrho cov kev cai ntawm cov neeg siv khoom.
