Itandukaniro riri hagati yindimu ya magnetiki na chip nyinshi

1.

Inductors ni ibikoresho bibika ingufu kandi amasaro ya magnetiki ni ibikoresho byo guhindura ingufu (gukoresha). Indimu ya SMT ikoreshwa cyane kugirango ihagarike kwivanga kwamashanyarazi. Amasaro ya magnetique akoreshwa cyane mubizunguruka, cyane cyane kuri EMI. Amasaro ya magnetique akoreshwa mugukuramo ibimenyetso bya UHF. Kurugero, imirongo imwe yumurongo wa radio, imirongo ifunze feri, oscillator zumuzunguruko hamwe na ultra-high frequency frequency yibuka (DDR, SDRAM, RAMBUS, nibindi) byose bigomba kongeramo amasaro ya magneti mugice cyinjiza amashanyarazi. Induction ya SMD ni ubwoko bwububiko bwingufu, bukoreshwa mumuzunguruko wa LC oscillator, urwego ruciriritse kandi ruto rwo muyunguruzi, nibindi.

2. Ni izihe nyungu zo kwinjiza amashanyarazi ya magneti mu biranga uruziga?
Imashini ya magnetiki ikoreshwa mu gukurura ibimenyetso bya ultra-high frequency, nka radiyo zimwe na zimwe za radiyo yumurongo wa radiyo, imirongo ifunze feri, imiyoboro ya oscillator, harimo na ultra-high frequency frequency (DDR SDRAM, RAMBUS, nibindi) Ubu bwoko bwo kubika ingufu ikoreshwa muri LC ihindagurika ryumuzingi, iringaniye na ntoya ya filteri yumuzunguruko, kandi ikoreshwa ryayo inshuro zirenga gake 50MHZ itari yo. Ihuza ryubutaka muri rusange rikoresha inductor, guhuza ingufu nabyo bikoresha inductor, kandi isaro ya magneti ikoreshwa kumurongo wibimenyetso? Ariko mubyukuri, amasaro ya magnetique nayo agomba gushobora kwinjirira inshuro nyinshi, sibyo? Kandi inductance ya inductance nyuma yumurongo mwinshi wa resonance ntishobora kugira uruhare….

3. Indanganturo ya chip iruta iyindi indangantanga ya magneti?

1. Inductance yanduye:

Ifite kandi uburyo bwiza bwo gukingira magnetique, ubwinshi bwicyaha, hamwe nimbaraga nziza za mashini, ugereranije nubushakashatsi bwumuyaga: ubunini buto, bufasha miniaturizasi yumuzunguruko, uruziga rukuruzi rwa magneti, ntiruzabangamira ibice bikikije, kandi ntibizagira ingaruka n'ibice bikikije Birafasha cyane kwishyiriraho ibice byinshi; imiterere ihuriweho hamwe ifite ubwizerwe buhanitse, irwanya ubushyuhe bwiza, igurishwa ryiza, nuburyo busanzwe, bukwiranye nubushakashatsi bwikora bwikora. Ikibi ni uko igipimo cyujuje ibisabwa kiri hasi, igiciro ni kinini, inductance ni nto, na Q agaciro ni nto. Muri rusange, inductor nyinshi ntishobora kubona umurongo, inductor ya multilayeri ifite ubushyuhe bwiza, kandi agaciro ka ESR ni nto. Amashanyarazi ya inductor angahe? Urashobora kutugisha inama kubisobanuro wifuza!

2. Ibyiza bya indimu ya SMD itandukanijwe nizindi inductor:
A. Ingano nto.
B. Kugurisha neza no kugurisha ibicuruzwa, bikwiranye no kugurisha ibicuruzwa no kugurisha ibicuruzwa.
C. Umuzunguruko ufunze, nta kwivanga, bikwiranye no kwishyiriraho cyane.
D. Ntabwo ari icyerekezo, gisanzwe kigaragara kubikoresho byikora.
