amakuru

Kuva indimu ya chip ifite ibintu nka miniaturizasiya, ubuziranenge bwo hejuru, kubika ingufu nyinshi, hamwe na DCR nkeya cyane, yagiye isimbuza buhoro buhoro insimburangingo gakondo mu bice byinshi. Mugihe inganda za elegitoronike zinjiye mugihe cya miniaturizasiya no gusibanganya, indimu za chip ziragenda zikoreshwa muburyo bwagutse bwa porogaramu. Igihe kimwe,indimuntoya na ntoya, nayo izana ingorane zo gusudira chip inductor.

Kwirinda gusudira mbere

Bitewe nubunini bwacyo kandi buto, hariho itandukaniro ryinshi hagati yo kugurisha indimu ya chip na plug-in inductor. Ni iki kigomba kwitonderwa mugihe cyo kugurisha indimu?

1. Mbere yo gusudira inductor ya chip, ni ngombwa kwitondera ubushyuhe kugirango wirinde ihungabana ryumuriro mugihe cyo gusudira.

2. Ubushyuhe bwo gushyushya busaba kuzamuka buhoro, byaba byiza 2 ℃ / amasegonda, kandi ntibigomba kurenza 4 ℃ / amasegonda.

3. Reba itandukaniro ryubushyuhe hagati yubushyuhe bwo gusudira nubushyuhe bwo hejuru Mubisanzwe, itandukaniro ryubushyuhe hagati ya 80 ℃ na 120 ℃ nibisanzwe.

4. Mugihe cyo gusudira, twakagombye kumenya ko guhagarika ubushyuhe biziyongera hamwe no kwiyongera kwubunini bwa chip inductor.

Kugurisha

Kwibiza mumaso yanyuma ya chip inductor mu itanura ryamabati kuri 235 ± 5 ℃ kumasegonda 2 ± 1 birashobora kugera kubisubizo byiza byo kugurisha.

Gukoresha flux mugihe cyo gusudira

Guhitamo ibicuruzwa bikwiye bifasha kurinda ubuso bwa inductor. Reba ingingo zikurikira.

1. Menya ko hatagomba kubaho acide zikomeye muri flux mugihe cyo gusudira inductor ya patch. Bikunze gukoreshwa mugukora rosin yoroheje.

2.Niba hatoranijwe amazi-soluble flux, hagomba kwitonderwa byumwihariko isuku ya substrate mbere yo gusudira.

3.Ku rwego rwo kwemeza gusudira neza, witondere gukoresha flux nkeya zishoboka.

Kwirinda inzira yo gusudira

1.Koresha kugurisha ibicuruzwa bishoboka kugirango wirinde kugurisha intoki.

2. Menya ko kugurisha imiraba bidasabwa kubushakashatsi bwa chip burenze ubunini bwa 1812. Kuberako iyo inductor ya chip yibijwe mumiraba yo gusudira yashongeshejwe, hazabaho ubushyuhe bukabije, mubisanzwe 240 ℃, bushobora kwangiza inductor bitewe nubushyuhe bwumuriro.

3. Gukoresha icyuma kigurisha amashanyarazi kugirango usudire inductor ya chip ntabwo ikwiriye cyane, ariko mugihe mubushakashatsi bwa injeniyeri no mubikorwa byiterambere, birakenewe gukoresha icyuma cyo kugurisha amashanyarazi kugirango intoki zogosha intoki. Hano hari ibintu bitanu ugomba kumenya

(1) Shyushya uruziga na inductor kugeza kuri 150 ℃ mbere yo gusudira intoki

(2) Icyuma kigurisha ntigomba gukora ku mubiri wa chip inductor

(3) Koresha icyuma kigurisha gifite watt 20 na diametero 1.0

(4) Ubushyuhe bwo kugurisha ni 280 ℃

(5) Igihe cyo gusudira ntigishobora kurenga amasegonda atatu

Kubindi bisobanuro, nyamuneka wumve nezatwandikire.
