Impumyi yashyinguwe Vias PCB
PCB ibinyujije muri vias irashobora kugabanywamo binyuze, impumyi ikanyuzwa hamwe.Impumyi ya burrow PCBs irashobora kuba igisubizo mugihe ushaka gushyira VTH ihagije kubibaho ariko umwanya ni muto.Impumyi zihumye zikoreshwa muguhuza PCB murwego rwo hejuru.Impumyi ikoresheje ni amashanyarazi akoresheje guhuza igice kimwe cyinyuma gusa kumurongo umwe cyangwa nyinshi imbere.Viyasi yashyinguwe ni amashanyarazi akoreshwa ahuza ibice bibiri cyangwa byinshi byimbere ariko ntaho bihuriye nigice cyo hanze.
Inyungu Zimpumyi Zashyinguwe Vias PCB
1. Imipaka yubucucike bwinsinga hamwe nudupapuro mubishushanyo birashobora kubahirizwa utarinze kongera umubare wibice cyangwa ubunini bwumuzunguruko
2. Mugabanye igipimo cyumuzingi wa PCB
Impumyi ikoresheje / yashyinguwe binyuze muri PCB kugirango ihuze ubwinshi bwubuyobozi butongereye umubare wibice cyangwa ubunini bwibibaho.Kubwibyo, impumyi / zishyinguwe zikoreshwa muri HDI PCBs.Akenshi ikoreshwa muri terefone zigendanwa, itumanaho ridafite umugozi, MID.Ikaye.
