Ibigize ikibaho cyumuzingo cyacapwe (PCB)

1. Umurongo

Icapa ryumuzunguruko (PCB) igabanyijemo ibice byumuringa nubundi butari umuringa, bikunze kuvugwa ko ibice bike byubuyobozi ari ukugaragaza umubare wumubare wumuringa.Mubisanzwe, gusudira amakariso n'imirongo bishyirwa kumurongo wumuringa kugirango urangize amashanyarazi.Shyira ibintu bisobanura imiterere cyangwa ibisobanuro kubitekerezo bitari umuringa;Ibice bimwe (nkibikoresho byubukanishi) bikoreshwa mugushira amakuru yerekana ibijyanye no gukora ikibaho nuburyo bwo guterana, nkumurongo wibipimo bifatika byubuyobozi, ibimenyetso byerekana ibipimo, amakuru yamakuru, binyuze mumakuru yumwobo, amabwiriza yo guterana, nibindi.

2.Via

Binyuze mu mwobo ni kimwe mu bice byingenzi bigize PCB.Igiciro cyo gucukura umwobo mubusanzwe ni 30% kugeza 40% yikiguzi cyumuzingo wacapwe (PCB).Muri make, buri mwobo uri kuri PCB urashobora kwitwa umwobo.Duhereye ku buryo bwo gukora, kunyura mu mwobo birashobora kugabanywamo ibyiciro bibiri: kimwe gikoreshwa nk'umuyoboro w'amashanyarazi hagati ya buri cyiciro;Iya kabiri ikoreshwa mugukosora cyangwa gushakisha ibikoresho.Kubireba inzira yikoranabuhanga, umwobo muri rusange ugabanijwemo ibyiciro bitatu, ni ukuvuga impumyi binyuze.Yashyinguwe binyuze no kunyura.

3. Pad

Padiri ikoreshwa mugusudira ibice, kumenya imiyoboro y'amashanyarazi, gutunganya pin yibigize cyangwa gushushanya insinga, imirongo yo kugerageza, nibindi. Ukurikije ubwoko bwa paki yibigize, padi irashobora kugabanywamo ibyiciro bibiri: padi yinjizamo inshinge nubuso ipaki.Urupapuro rwo gushiramo inshinge rugomba gucukurwa, mugihe ipamba yo hejuru idakenera gucukurwa.Isahani yo gusudira yubwoko bwinjizamo inshinge yashyizwe mubice byinshi, kandi isahani yo gusudira yibice byubwoko bwa SMT yashyizwe mubice bimwe hamwe nibigize

4.Gukurikirana

Umugozi wa firime wumuringa ni insinga ikora kuri PCB nyuma yo gutunganya isahani yumuringa.Byitwa insinga kubugufi.Mubisanzwe bikoreshwa mugutahura isano iri hagati yipadiri kandi nigice cyingenzi cyibibaho byacapwe (PCB).Umutungo wingenzi wumugozi nubugari bwawo, biterwa nubunini bwo gutwara amashanyarazi hamwe nubunini bwumuringa wumuringa.

5. Ibikoresho

Ipaki yibigize bisobanura gusudira ibice bifatika kubibaho byacapwe (PCB) kugirango biyobore pin hanze.Noneho ibipapuro byagenwe bihinduka byose.Ubwoko busanzwe bwa encapsulation ni plug-in encapsulation hamwe nubuso bwashyizwe hejuru.
