Ikibaho cyumuzunguruko igizwe nibice byumuringa wumuringa wumuringa, kandi ihuriro riri hagati yumuzunguruko utandukanye rishingiye kuri "vias".Ni ukubera ko uyumunsi ikibaho cyumuzunguruko gikoresha umwobo wacukuwe kugirango uhuze imirongo itandukanye.Hagati yumuzunguruko, birasa numuyoboro uhuza inzira nyinshi zamazi yo munsi y'ubutaka.Inshuti zakinnye umukino wa videwo "Umuvandimwe Mariya" zishobora kuba zizi guhuza imiyoboro y'amazi.Itandukaniro nuko imiyoboro y'amazi isabwa kugirango amazi azenguruke (Ntabwo agomba gucukurwa umuvandimwe Mariya), kandi intego yo guhuza ikibaho cyumuzunguruko ni ugukoresha amashanyarazi kubiranga amashanyarazi, bityo byitwa kunyura mumwobo, ariko niba ukoresha gusa imyitozo cyangwa laser kugirango ucukure umwobo, ntabwo bizayobora amashanyarazi.Kubwibyo rero, igice cyibikoresho bitwara ibintu (mubisanzwe "umuringa") bigomba guhindurwa amashanyarazi hejuru yumwobo wacukuwe, kugirango electron zishobore kugenda hagati yumuringa utandukanye wumuringa, kuko hejuru yumwobo wambere wacukuwe ni resin gusa idakora. kuyobora amashanyarazi ya.
Binyuze mu mwobo: Gushyira mu mwobo byitwa PTH
Ubu ni ubwoko busanzwe bwa binyuze mu mwobo.Ukeneye gusa gufata PCB ukareba urumuri, umwobo ushobora kubona urumuri rwinshi ni "unyuze mu mwobo".Ubu kandi nubwoko bworoshye cyane bwumwobo, kuko mugihe ubikora, ugomba gusa gukoresha umwitozo cyangwa laser kugirango ucukure neza ikibaho cyumuzunguruko, kandi ikiguzi kirahendutse.Ariko kurundi ruhande, ibice bimwe byumuzunguruko ntibikeneye guhuza ibi binyuze mumyobo.Kurugero, dufite inzu yamagorofa atandatu.Ikidubu gikora gifite amafaranga menshi.Naguze igorofa yacyo ya gatatu n'iya kane.Noneho, idubu ikora ubwayo iri muri etage ya gatatu.Ingazi yateguwe hagati ya etage ya kane kugirango ivugane, kandi idubu ikora ntabwo ikeneye guhuza andi magorofa.Muri iki gihe, niba indi ngazi yagenewe kunyura muri buri igorofa kuva mu igorofa rya mbere kugeza mu wa gatandatu, bizaba impfabusa.Hamwe nimbaho yumuzunguruko Inch zahabu ntigomba kwemererwa.Nubwo rero binyuze mu mwobo bihendutse, rimwe na rimwe bakoresha umwanya munini wa PCB.
Umuyoboro w'impumyi: Impumyi zinyuze mu mwobo (BVH) Umuzenguruko wo hanze wa PCB uhujwe nigice cyimbere cyegeranye hamwe nu mwobo washyizweho, ariko ntabwo unyuze, kuko uruhande rutandukanye ntirushobora kuboneka, bityo rwitwa "umwobo uhumye".Kugirango twongere imikoreshereze yumwanya wumurongo wa PCB, hagaragaye inzira "impumyi binyuze".Ubu buryo bwo gukora busaba kwitondera byimazeyo ubujyakuzimu (Z axis) kugira ngo bibe byiza, ariko ubu buryo akenshi butera ingorane zo gukwirakwiza amashanyarazi mu mwobo, bityo rero ntanumwe wabikoze yabyemeje. Birashoboka kandi gucukura umwobo kubice byumuzunguruko bigomba guhuzwa murwego rwumuzunguruko mbere, hanyuma ukabihambira hamwe.Ikibaho cya 2 + 4 kirimo, ariko ibi birasaba igikoresho gisobanutse neza kandi gihuza. Fata urugero rwavuzwe haruguru rwo kugura inyubako.Inzu y'amagorofa atandatu ifite gusa ingazi zihuza igorofa ya mbere n'amagorofa ya kabiri, cyangwa ingazi zihuza igorofa ya gatanu na etage ya gatandatu, zitwa umwobo uhumye. "Ibyobo bihumye" ni ibyobo bishobora kugaragara kuruhande rumwe rwibibaho, ariko ntabwo kurundi ruhande rwibibaho.
Yashyinguwe binyuze: Yahambwe Binyuze mu mwobo (BVH) Inzira zose zumuzingi imbere muri PCB zirahujwe ariko ntizihujwe kurwego rwo hanze.Iyi nzira ntishobora kugerwaho mugucukura nyuma yo guhuza.Igomba gucukurwa kumurongo wumuzingi.Igice cyimbere kimaze guhuzwa igice, kigomba kuba amashanyarazi mbere yuko gihuza byuzuye.Ugereranije numwimerere "unyuze mu mwobo" Kandi "umwobo uhumye" usaba akazi kenshi, bityo igiciro nicyo gihenze cyane.Ubu buryo busanzwe bukoreshwa gusa kubibaho byumuzunguruko mwinshi (HDI) kugirango wongere umwanya ukoreshwa mubindi bice byumuzunguruko.Fata urugero rwo kugura inyubako hejuru.Inzu y'amagorofa atandatu ifite gusa ingazi zihuza igorofa ya gatatu n'iya kane, bita imyobo yashyinguwe. "Gushyingura umwobo" bivuze ko umwobo udashobora kugaragara uhereye ku kibaho, ariko umwobo nyirizina ushyinguwe mu gice cy'imbere cy'ikibaho.
