PCB ni impfunyapfunyo yumurongo wumuzingo wanditse mucyongereza. Inzira zacapwe zikunze kwitwa uburyo bwo kuyobora bukozwe mumuzingo wacapwe, ibice byacapwe, cyangwa guhuza byombi, bishingiye kubishushanyo mbonera byateganijwe kubikoresho. Uburyo bwo kuyobora butanga amashanyarazi hagati yibigize kuri insulateri yiswe byitwa umuzenguruko wacapwe. Muri ubu buryo, ibicapo byacapwe cyangwa imbaho ​​zarangiye zumuzingo wacapwe byitwa imbaho ​​zicapye, bizwi kandi nkibibaho byacapwe cyangwa imbaho ​​zicapye. Kuri PCB yibanze cyane, ibice byibanze kuruhande rumwe naho insinga zegeranijwe kurundi ruhande. Kuberako insinga zigaragara kuruhande rumwe gusa, twita ubu bwoko bwa PCB kuruhande rumwe PCB. Kuberako PCB imwe imwe ifite imbogamizi zikomeye muburyo bwo kuzunguruka, kuko zifite uruhande rumwe gusa, insinga ntishobora gutandukana kandi igomba kugenda yigenga.

PCB ihindagurika yakoreshejwe cyane ku isoko kandi yabaye ibicuruzwa byingirakamaro mu nganda za elegitoroniki. Irashobora guhuza nibikorwa bitandukanye bya PCB byoroshye, nkibikoresho byambarwa, ingingo zubuhanga, ibikoresho byubuvuzi, modul ya RFID, nibindi. Ihuriro rya PCB rikomeye kandi ryoroshye rikoreshwa cyane cyane kuri terefone igendanwa nibicuruzwa byambarwa. Byombi byoroheje kandi byoroshye PCBs itanga ibishushanyo bihamye hamwe nuburyo bworoshye bwo kwimuka cyangwa kunyeganyeza ibicuruzwa.

PCBs yoroheje PCBs irashobora kugororwa, kuzingirwa, cyangwa kuzunguruka, hanyuma igashyirwa mubicuruzwa bitandukanye. Zitanga ubworoherane, guhinduka, no kugenda kubikoresho byikurura. Harimo amakarita yo kwagura na bateri kuri mudasobwa zigendanwa cyangwa mudasobwa ya desktop. Igice cyoroshye cya PCB kirashobora kugororwa cyangwa kugoramye, ariko ntabwo byoroshye nkibibaho byoroshye guhuza ikibaho. Nibisubizo byigikoresho cyibikoresho byoroshye kuko bidasaba guhuza gukomeye mubice bifite umuhanda munini wabanyamaguru, kuko bishobora kunama bitavunitse cyangwa ngo bitandukane. Iyi blog yanditse izinjira mubikorwa bitandukanye bya PCB yoroheje kandi yoroheje ya PCB.

Ikibaho cyumuzunguruko cyacapwe (PCB), kizwi kandi nk'icapiro ry'umuzunguruko cyangwa icapiro ry'umuzunguruko. Ibibaho byinshi byacapwe bivuga ku mbaho ​​zacapwe zifite ibice birenga bibiri, bigizwe no guhuza insinga ku byiciro byinshi byo kubika insimburangingo hamwe n’ibikoresho byo kugurisha bikoreshwa mu guteranya no gusudira ibikoresho bya elegitoroniki. Ntabwo bafite umurimo wo kuyobora imirongo ya buri cyiciro, ariko bafite n'umurimo wo kwigizanya.

Ikibaho kinini cya PCB bivuga ikibaho cyumuzunguruko cyinshi gikoreshwa mubicuruzwa byamashanyarazi, bikoresha ibyuma byinshi cyangwa bibiri. Ikibaho cyumuzunguruko cyanditse gikoresha uruhande rumwe rwimbere rwimbere, ibice bibiri byo hanze byuruhande rumwe, cyangwa ibice bibiri byimbere byimbere, hamwe nibice bibiri byo hanze, kandi bigahuzwa nigishushanyo mbonera gikurikije ibishushanyo mbonera ukoresheje sisitemu yo guhagarara hamwe nibikoresho byuzuzanya, bihinduka icyapa cyumuzingo cyacapishijwe ibice byinshi.

Urufatiro rwicyuma rugizwe nicyuma fatizo, icyuma cyiziritse, hamwe numuzunguruko wumuringa. Nibikoresho byumuzunguruko wibyuma bigizwe nibikoresho rusange bya elegitoroniki, bigizwe nubushyuhe bwumuriro, icyuma, hamwe nicyuma. Ifite imbaraga zidasanzwe za rukuruzi, gukwirakwiza ubushyuhe bwiza, imbaraga za mashini nyinshi, hamwe nuburyo bwiza bwo gutunganya.

Icyuma cyo gukuramo ibyuma kigizwe nicyuma cyububiko bwicyuma, icyuma gikingira, hamwe numuringa wambaye umuringa. Igice cyo hejuru ni umuringa wuzuye umuzenguruko, ubanza ugizwe numuringa. Ukurikije amashanyarazi asabwa guhuza, umuzenguruko urashobora kwangirika mukuzunguruka gusabwa. Imbaraga za tristoriste, chip igenzura chip, nibindi birashobora kugurishwa muburyo butaziguye umuringa wambaye umuringa. Mu rwego rwo koroshya gusudira no kwirinda okiside, ipaderi yagurishijwe yometseho Ti, Pt, Cu, Au nizindi firime zinanutse zahabu, ifite ubunini bwa microni 35, 50, 70105140; Urwego ruciriritse ni urwego ruciriritse, rusanzwe rukozwe muri epoxy ikirahuri cya fibre fibre yometse hamwe nubushyuhe bwiza bwumuriro, epoxy resin, cyangwa firime dielectric ya firime yuzuyemo ibikoresho byubutaka. Umubyimba wacyo ugabanijwemo ibintu bine: 50, 75, 100, 150 micron.

Ikibaho kinini PCB yerekana ubwoko bwihariye bwumuzunguruko ufite amashanyarazi menshi ya elegitoroniki, ikoreshwa mumirima yumurongo mwinshi (inshuro zirenga 300MHz cyangwa uburebure bwumuraba uri munsi ya metero 1) na microwave (inshuro zirenze 3GHz cyangwa uburebure bwa metero 0.1). Nibibaho byumuzunguruko bikozwe kuri microwave substrate yumuringa wambaye umuringa ukoresheje inzira zimwe zisanzwe zisanzwe zikora imashanyarazi cyangwa uburyo bwihariye bwo gutunganya.

Igice kinini cyumuringa PCB nigice gikura mubikorwa byacu. Kugirango dushyigikire iki gice cyingenzi, turimo guteza imbere umubano umaze igihe ninganda nyinshi zatoranijwe neza mugushakisha isoko.
