SMD Coil Guide: Inama, Kwishyira hamwe & Inyungu zumushinga

Intangiriro kuri Coil Coil

Amashanyarazi ya SMD ni iki?

SMD coil ni ikintu cyingenzi cya elegitoroniki ya none; batanga uburyo bworoshye kandi bworoshye bwo kwinjiza inductance mumuzunguruko. Ibi bikoresho biratandukanye nibisanzwe byinjira mubwoko bwa inductors kuberako bigenewe kwishyiriraho PCBs. Iyi mikorere irakomeye cyane mubidukikije bya elegitoroniki yumunsi, aho umwanya uri murwego rwo hejuru kandi kugabanya imyanda yo guterana ni ugushakisha buri gihe. Kumenyekanisha ibiceri bya tekinoroji ya SMD, byatumye byinshi muri EVM biba bito kandi byoroshye EVM, kandi bifite uburyo bwinshi bwo gukoresha mubikoresho bya elegitoronike nkibikoresho byitumanaho rigendanwa nibikoresho byubuvuzi bigezweho.

SMD coil iraboneka muburyo buteganijwe gukoreshwa muburyo butandukanye. Kurugero, ibyuma bikomeretsa insinga bizwi cyane kubera agaciro kinshi ka inductance, kandi bitanga imikorere myiza yo gukoreshwa mumashanyarazi no gukwirakwiza radiyo (RF). Hagati yabyo ni ibiceri byinshi bya SMD biha uwashushanyije ibyiza byisi byombi aho igipande cyubwubatsi bwa coil bivuze ko kubwinshi bwa inductance ingano yagabanutse. Iri tandukaniro ryemeza ko niba gusaba kwawe ari inshuro nyinshi, umwanya ufungiwe cyangwa ibikorwa binini bigezweho birashoboka ko SMD coil coil izahuza fagitire.

Byongeye kandi, kwinjizamo ibiceri bya SMD bihuye nuburyo bwo gukora byikora (nk'imashini zitwara-ahantu) byihutisha cyane inzira yo guhuza transceiver kandi bigira uruhare runini mubiciro. Uku guhuza na automatike ntabwo byongera umusaruro gusa, ahubwo binatanga ubuziranenge busubirwamo bwinteko za elegitoroniki. Hamwe na elegitoroniki ihora itera imbere, umwanya wa SMD coil mu nganda uracyiyongera, bivuze ko gukora neza no gushushanya biri hejuru murwego rwose rwa porogaramu.

Ibyiza byo gukoresha ibiceri bya SMD

SMD coil ifite ibyiza byinshi muburyo bwa elegitoroniki. Ibintu byabo bito, imiterere mike, hamwe na voltage yo hejuru ituma biba byiza mugihe umwanya ari ukureba. Morevoer, ni ubwoko bwa smd bushobora gutanga igishushanyo mbonera cya pcb kugirango uburinganire bwiza bwibimenyetso nibikorwa bya EMI. Mubyongeyeho, imikorere ya coil ya SMD irerekanwa kandi mugukoresha ingufu hamwe nubushyuhe bwumuriro bityo rero birashobora gukoreshwa kumurongo mwinshi wa porogaramu. Usibye kunoza imikorere yibikoresho, ibiceri bya SMD bitanga inyungu zo kwinjizwa mubishushanyo mbonera hanyuma amaherezo bikagabanya ikiguzi cyo gukora nigihe.

Porogaramu ya SMD Coil

SMD coil irashobora gukoreshwa muburyo butandukanye bwibicuruzwa nibikoresho bya elegitoroniki, bitewe nuburyo bwinshi. Ibi tubisanga cyane cyane mubitumanaho kubiyungurura na inductors, imiyoboro y'amashanyarazi kugirango ikore neza kandi iyungurure amashanyarazi, no mubisabwa byinshi bya RF aho ubunini bwuzuye kandi bworoshye aribintu bikenewe. Ibikoresho bya elegitoroniki bigendanwa (terefone ngendanwa, paje, PDA na kamera ya digitale, nibindi) nabyo bibara imikoreshereze myinshi ya coil ya SMD bitewe nubunini bwayo kandi bukora neza. Byongeye kandi, abakora amamodoka bakoresha ibyo bintu muburyo bwa sensor sisitemu na sisitemu yoroshye bityo bagashimangira akamaro ka coil ya SMD mugutezimbere ikoranabuhanga rigezweho mubikorwa bitandukanye.

Guhitamo Igiceri Cyiza cya SMD kumushinga wawe

Gusobanukirwa Ibisobanuro

Inzira yo guhitamo ibiceri byiza bya SMD kumushinga wawe bitangirana no gusobanukirwa nibisobanuro byayo. Inductance, kwihanganira, ibigezweho na Q biri mubintu byingenzi. Ibipimo bya inductance bitangwa muri Henries (H) kandi bisobanura ubushobozi bwa coil yo kubika ingufu mumashanyarazi, ikintu cyingenzi cyane cyane mugushungura no kubika ingufu. Ubworoherane ni itandukaniro muri inductance yemerewe kuva ku giciro cyagenwe ubwacyo kigira ingaruka kumyizerere yawe. Igipimo kiriho (cyangwa amp) nicyo kintu cyingenzi gitekerezwaho kuko nubushobozi bwa coil kugirango ikemure ingano yumuriro bisaba kugirango ukoreshe umutwaro wamashanyarazi utarashyuha cyane kugeza aho ucumba kandi ukangiza. Hanyuma, Q ibintu bigereranya imikorere ya coil kuri resonance kandi nini Q nini, niko gutakaza ingufu.

Ubwoko bwa Coil Coil

SMD coil iraboneka mubishushanyo bitandukanye kubikorwa bitandukanye. Ubwoko bumwe busanzwe ni bwinshi, igikomere cyinsinga hamwe na firime yoroheje. Ibice byinshi bya coil muyunguruzi ntibihendutse kandi bito mubunini, kubwibyo, birakwiriye kubikorwa rusange mugushungura no gutunganya ibimenyetso. Ibikomere by'insinga bitanga inductance yo hejuru hamwe nu rutonde rwibikoresho bitanga amashanyarazi na RF. Inductance nyayo nibintu byinshi Q yibintu byoroshye bya firime birakwiriye gukoreshwa mumashanyarazi menshi. Kumenya ubwoko butandukanye nibyingenzi muguhitamo coil nziza kumushinga wawe.

Urashobora guhitamo ubwoko bwa inductor iburyo bwa porogaramu yawe mugupima ibikenewe byihariye mubikorwa, ingano, ikiguzi no gukora neza. Buri bwoko bugira ibyiza byabwo bitewe nurwego rwinshyi, urwego rwifuzwa nu mwanya uhari.

Ibintu ugomba gusuzuma mugihe uhisemo

Hano haribintu byinshi byingenzi ugomba gusuzuma mugihe uhisemo SMD coil yo gusaba. Menya inshuro zikoreshwa mubikorwa byawe. Kubishobora gukoreshwa cyane-coil hamwe na Q yo hejuru irashobora gukenerwa kugirango igabanye ingufu. Agace kaboneka kuri PCB yawe (Icapiro ryumuzunguruko wacapwe) naryo rizagena ingano ya coil ushobora gukoresha, kubwibyo ingano hamwe nibintu byingenzi ni ibintu byingenzi ugomba gusuzuma. Na none, ubushyuhe, ubushuhe, nubundi bwoko bwibidukikije kuri coil birashobora kugira ingaruka kumikorere no mubuzima bwe, ibi bituma guhitamo ibikoresho hamwe no gutwikisha umwanzuro wingenzi. Kumenya ibipimo bituma ukora igiceri cya SMD wahisemo ntiguhaza gusa ibyo ukeneye bya tekiniki, ariko kandi bihuye numubiri nibidukikije byumushinga wawe.

Kwinjiza ibiceri bya SMD mubishushanyo byawe

Ibishushanyo mbonera

Iyo ushushanya hamwe na coil ya SMD, ni ngombwa kumenya aho amashanyarazi agarukira. Ugomba guhitamo igiceri cya SMD ukurikije inductance yacyo, igipimo cyubu, Q nibindi biranga. Ingano nyayo n'ibirenge bifatika bya coil birakomeye nkuko bikenewe guhuza umwanya uboneka kuri PCB yawe. Ibintu bidukikije birimo ubushyuhe bwimikorere no guhura nubushuhe nabyo bigomba gutekerezwa kuko bishobora kugira ingaruka zigaragara kumikorere nubuzima bwa coil. Imyiteguro myiza muriki cyiciro izorohereza inzira yo kwishyira hamwe byoroshye kandi bihenze cyane mugihe kirekire.

Inama zo kugurisha no guterana

SMD coil isanzwe iboneka muburyo bunini bwubunini nagaciro. Kugurisha ibiceri bya SMD bisaba igihe no kwihangana. Kubicuruzwa byizewe byingirakamaro, gukoresha ubushyuhe bugenzurwa nicyuma kirasabwa cyane kandi bifite ireme, ntagishobora gukoreshwa neza. Mugushushanya PCB urashobora gukuraho ihungabana iryo ariryo ryose kuri coil ya SMD. Kugaburira padi / ibice biganisha / gufatanya icyarimwe gukoraho hamwe nuwagurishije icyuma kugurisha icyuma / ibice biganisha kubigurisha neza. Ntuzigere ushyuha ubundi ubushyuhe burashobora kwangiza coil cyangwa PCB.

Umaze gukora kugurisha, genzura buri gihuza munsi ya lens cyangwa microscope kugirango umenye neza ko nta bihuza bikonje cyangwa ibiraro bikonje. Niba hari igihe ugomba gukoraho ikintu hejuru, menya neza ko ushyira flux hanyuma ususurutsa hamwe hamwe nu mucuruzi mushya ushoboka. Uku kwitondera amakuru arambuye bigiye gutanga amashanyarazi meza azagufasha neza mumyaka iri imbere.

Kwipimisha no Gukemura Ibibazo

Nyuma yo kugurisha ibiceri bya SMD kuri PCB, ni ngombwa kugenzura ko bikora, kugirango umushinga wawe ukomeze gukora ibyo ugomba gukora. Banza urebe n'amaso yawe niba ibishishwa byose bishyizwe neza kandi niba kugurisha bisa neza. Koresha multimeter kugirango ugerageze ibintu byayobowe mugenzura inductance hamwe nuburwanya bwa buri cyerekezo kirwanya ibisobanuro. Ikintu cyose gitandukanye cyane cyerekanaga ikibazo hamwe na coil, cyangwa umugurisha mubi.

Mugihe wahuye nibibazo nkibisanzwe bidasanzwe byo gusoma, inzinguzingo ngufi nibindi, hanyuma ugenzure kabiri Solderings yawe kugirango ushakishe icyuho cyikiraro hamwe nabandi bagurisha / bakonje. Rimwe na rimwe, igiceri cya SMD kigomba guhinduka. Kugenzura imbaraga zawe zose zo kugerageza no gukemura ibibazo birashobora kuba inzira nziza yo gushakisha no gukemura ibibazo uhura nabyo, kandi bikagufasha kurushaho guterana neza.
