Ni ubuhe buryo busanzwe bwo guhitamo ibice nibikoresho mugihe inteko PCB?

Gutunganya inteko ya PCB birimo igishushanyo mbonera cyacapwe, prototyping ya PCB,Ubuyobozi bwa SMT PCB, ibice biva hamwe nibindi bikorwa.None, ni ibihe bice bigize PCBA itunganya ibice hamwe nuburyo bwo guhitamo substrate?

1. Guhitamo ibice

Guhitamo ibice bigomba gufata konti yuzuye yubuso bwa SMB, nibisanzwe bigomba guhitamo kure hashoboka.Ibice bito bito ntibigomba gukurikiranwa buhumyi kugirango birinde kongera ibiciro.Ibikoresho bya IC bigomba kumenya ko imiterere ya pin hamwe nintera ya pin;QFP ifite intera iri munsi ya 0.5mm pin igomba gutekerezwa neza, urashobora gukoresha pake ya BGA.

Byongeye kandi, uburyo bwo gupakira ibice, kugurishwa kwa PCB, kwizerwa kwiteraniro rya SMT PCB, hamwe nubushobozi bwo gutwara ubushyuhe bigomba kwitabwaho.Nyuma yo guhitamo ibice, ububiko bwibigize bigomba gushyirwaho, harimo ingano yubushakashatsi, ingano ya pin hamwe nuwakoze SMT nandi makuru afatika.

2.Guhitamo ibikoresho fatizo kuri PCB

Ibikoresho fatizo bizatoranywa hakurikijwe serivisi ya SMB n'ibisabwa mu mashini n'amashanyarazi.Umubare wumuringa wuzuye umuringa (umwe, kabiri cyangwa ibice byinshi) bya substrate ugenwa ukurikije imiterere ya SMB;ubunini bwa substrate bugenwa ukurikije ubunini bwa SMB hamwe nubwiza bwibigize kuri buri gace.Mugihe uhisemo insimburangingo ya SMB, ibintu nkibisabwa mumashanyarazi asabwa, agaciro ka Tg (ubushyuhe bwikirahure), CTE, uburinganire nigiciro nibindi… bigomba kwitabwaho.

Ibyavuzwe haruguru nincamake ngufi yaicapiro ryumuzungurukogutunganya ibice hamwe na substrate yo guhitamo.Kubindi bisobanuro, urashobora gusura kurubuga rwacu: www.pcbfuture.com kugirango umenye byinshi!
