Ibyerekeye Via-Muri-Pad PCB

Via-In-Pad PCBs muri rusange ni ibyobo bihumye, bikoreshwa cyane cyane muguhuza igice cyimbere cyangwa igice cya kabiri cyinyuma cya HDI PCB nigice cyo hanze, kugirango tunoze imikorere yamashanyarazi nubwizerwe bwibicuruzwa bya elegitoronike, gabanya ibimenyetso insinga zohereza, gabanya reaction ya inductive na capacitive reaction yumurongo wogukwirakwiza, kimwe nimbaraga zo mumashanyarazi nizimbere.

Byakoreshejwe mu kuyobora.Ikibazo nyamukuru cyo gucomeka mu nganda za PCB ni ugutemba amavuta ava mu byobo, twavuga ko ari indwara ikomeje mu nganda.Ihindura cyane ubwiza bwumusaruro, igihe cyo gutanga no gukora neza PCB.Kugeza ubu, PCBs nyinshi zo mu rwego rwo hejuru zifite ubu bwoko bwo gushushanya.Kubwibyo, inganda za PCB zikeneye byihutirwa gukemura ikibazo cyamavuta ava mumyobo

Ibintu Bikuru byamavuta yoherezwa muri Via Muri Pad Plug Hole

Umwanya uri hagati yumwobo na padi: mubikorwa nyabyo bya PCB birwanya gusudira, usibye umwobo wa plaque biroroshye guhunga.Ibindi byacometse hamwe nu idirishya biri munsi ya 0.1mm 4mil) hamwe nu mwobo wacometse hamwe na anti-kugurisha idirishya tangensi, isahani ihuza nayo iroroshye kubaho nyuma yo gukiza amavuta yamenetse;

Ubunini bwa PCB hamwe na aperture: uburebure bwa plaque hamwe na aperture bifitanye isano neza nurwego nigipimo cyo gusohora amavuta;

Igishushanyo mbonera cya firime: mugihe Via-In-Pad PCB cyangwa umwobo muto utandukanijwe uhuza padi, firime ya paralelike muri rusange izashushanya aho itumanaho ryerekanwa mumadirishya (kugirango yerekane wino mumwobo) "kugirango wirinde wino umwobo winjira muri padi mugihe cyiterambere, ariko igishushanyo mbonera cyohereza urumuri ni gito cyane kugirango ugere ku ngaruka zo guhura, kandi ahohereza urumuri ni runini cyane kuburyo byoroshye gutera offset.Yibyara amavuta yicyatsi kuri PAD.

Ibihe byo gukiza: kubera ko igishushanyo mbonera cya Via-In-Pad PCB kuri firime kigomba kuba gito kuruta umwobo, igice cya wino mu mwobo kiba kinini kuruta aho cyoroshye iyo gishyizwe ahagaragara ntigaragare ku mucyo.Inkingi ntabwo ikiza kwifotoza, iterambere nyuma yubusanzwe ikeneye guhindura imiterere cyangwa UV inshuro imwe, kugirango ikize wino hano.Igice cyo gukiza firime gikozwe hejuru yumwobo kugirango hirindwe kwaguka kwinshi kwa wino mumwobo nyuma yo gukira.Nyuma yo gukira, igihe kinini cyicyiciro cyo hasi yubushyuhe, hamwe nubushyuhe bwo hasi yubushyuhe buke, niko umubare ugereranije nurwego rwohereza amavuta;

Gucomeka wino: abakora inganda zitandukanye za wino ingaruka nziza nazo zizagira itandukaniro runaka.
