Binyuze mu mwobo muburyo bwihuse PCB

Muburyo bwihuse bwa PCB, umwobo usa nkuworoshye akenshi uzana ingaruka mbi mubishushanyo mbonera.Binyuze mu mwobo (VIA) ni kimwe mu bintu by'ingenzi bigizeimbaho ​​nyinshi za PCB, hamwe nigiciro cyo gucukura mubisanzwe bingana na 30% kugeza 40% byikiguzi cya PCB.Muri make, buri mwobo muri PCB urashobora kwitwa guca mu mwobo.

Duhereye ku mikorere, imyobo irashobora kugabanywamo ubwoko bubiri: imwe ikoreshwa muguhuza amashanyarazi hagati yizindi, indi ikoreshwa mugukosora ibikoresho cyangwa guhagarara.Kubyerekeranye nibikorwa byikoranabuhanga, ibyo byobo bigabanijwemo ibyiciro bitatu, aribyo impumyi zinyuze, buji zinyuze.

Kugirango ugabanye ingaruka mbi ziterwa ningaruka za parasitike ya pore, ibintu bikurikira birashobora gukorwa uko bishoboka kwose mugushushanya:

Urebye ikiguzi hamwe nubuziranenge bwibimenyetso, hatoranijwe umwobo uringaniye.Kurugero, kuri 6-10 layer yibuka module PCB igishushanyo, nibyiza guhitamo umwobo wa 10 / 20mil (umwobo / padi).Kubintu byinshi-binini bito bito, urashobora kandi kugerageza gukoresha umwobo wa 8 / 18mil.Hamwe nikoranabuhanga rigezweho, biragoye gukoresha utuntu duto duto.Kubitanga amashanyarazi cyangwa umwobo wubutaka birashobora gufatwa nkugukoresha ubunini bunini, kugirango ugabanye inzitizi.

Duhereye kuri formula ebyiri zaganiriweho hejuru, dushobora kwemeza ko gukoresha ikibaho cyoroshye PCB bifite akamaro mukugabanya ibice bibiri bya parasitike ya pore.

Amapine yo gutanga amashanyarazi nubutaka agomba gucukurwa hafi.Mugihe kigufi kiyobora hagati yipine nu mwobo, nibyiza, kuko bizatuma kwiyongera kwa inductance.Muri icyo gihe, amashanyarazi hamwe nubutaka bigomba kuba binini cyane kugirango bigabanye inzitizi.

Ikimenyetso cyerekana kuriikibaho cyihuta cya PCBntigomba guhindura ibice bishoboka, nukuvuga kugabanya imyobo idakenewe.

Imyobo imwe yashizwemo ishyirwa hafi yumwobo murwego rwo guhanahana ibimenyetso kugirango itange hafi yikimenyetso.Urashobora no gushyira byinshi mubutaka bwubutaka kuriUbuyobozi bwa PCB.Birumvikana ko ugomba guhinduka mugushushanya kwawe.Icyerekezo cyanyuze mu mwobo cyaganiriweho hejuru gifite padi muri buri cyiciro.Rimwe na rimwe, turashobora kugabanya cyangwa no gukuraho padi mubice bimwe.

Cyane cyane kubijyanye n'ubucucike bunini cyane, burashobora gutuma habaho ishyamba ryacitse mubice byumuringa byumuzunguruko.Kugira ngo iki kibazo gikemuke, usibye kwimura umwanya wa pore, dushobora no gutekereza kugabanya ubunini bwa padiri yagurishijwe murwego rwumuringa.

Uburyo bwo gukoresha hejuru yumwobo: Binyuze mu isesengura ryavuzwe haruguru ryerekana parasitike iranga umwobo, dushobora kubibona muriPCB yihutaigishushanyo, bisa nkibyoroshye gukoresha nabi imyobo akenshi bizana ingaruka mbi mubishushanyo mbonera.
