Uru ni urwego 2umuringaPCB yakumurikainganda.Ikigo Cyuma Cyacapwe Cyumuzunguruko (MCPCB), cyangwa PCB yumuriro, ni ubwoko bwa PCB bufite ibikoresho byicyuma nkibishingiro byigice cyo gukwirakwiza ubushyuhe bwinama.

Ibyuma Byibanze PCB cyangwa MCPCB
Ibyuma Core PCB (MCPCB) izwi nka Metal Backplane PCB cyangwa Ubushyuhe bwa PCB.Ubu bwoko bwa PCB bukoresha ibikoresho byicyuma aho gukoresha FR4 isanzwe kugirango ibe ishingiro, igice cyo gushyushya ibice.
As irazwiubushyuhe butangwa ku kibaho kubwimpamvu ibice bya elegitoronike mugihe ikora.Ibyuma byohereza ubushyuhe buva mukibaho cyumuzunguruko hanyuma kukuyobora kuri Metal core cyangwa icyuma gishyushya ibyuma inyuma hamwe no kuzigama byingenzi Element.
Muri PCB igizwe nabantu benshi uzasangamo umubare umwe wibice byagabanijwe kuruhande rwicyuma.Kurugero, niba urebye Kuri PC-12-PCB, uzasangamo ibice bitandatu hejuru naho ibice bitandatu hepfo, hagati ni icyuma.
MCPCB cyangwa Ibyuma Byibanze PCB Bizwi kandi nka ICPB cyangwa Isohora Ibyuma PCB, IMS cyangwa Ibyuma Byubatswe Byuma, PCBs Byuma Byuma na PCB.
Fcyangwa wowe Kugira ngo ubyumve neza tuzakoresha gusa ijambo ibyuma byibanze PCB muriyi ngingo.
Imiterere shingiro yicyuma cyibanze PCB ikubiyemo ibi bikurikira:
Umuringa - 1oz.to 6oz.(ibisanzwe ni 1oz cyangwa 2oz)
umuzenguruko
Igice cya dielectric
Mask
Shyushya cyangwa ubushyuhe (icyuma cyibanze)
Inyungu kuri MCPCB
Amashanyarazi
CEM3 cyangwa FR4 ntabwo ari byiza kuyobora ubushyuhe.niba bishyushye
Substrates ikoreshwa muri PCBs ifite ubushobozi buke kandi irashobora kwangiza ibice byubuyobozi bwa PCB.Nibwo ibyuma byibanze PCBs biza bikenewe.
MCPCB ifite ubushyuhe bwiza cyane bwo kurinda ibice kwangirika.
Hkurya ibiryo
Itanga ubushobozi bwiza bwo gukonjesha.Ibyuma byibanze PCBs birashobora gukwirakwiza ubushyuhe muri IC neza.Ubushyuhe bwo gutwarwa nubushyuhe noneho bwohereza ubushyuhe kuri substrate yicyuma.
Igipimo gihamye
Itanga urwego rwo hejuru kurenza ubundi bwoko bwa PCBs.Ubushyuhe bumaze guhinduka kuva kuri dogere selisiyusi 30 kugera kuri dogere selisiyusi 140-150, ihinduka ryibipimo byibyuma bya aluminium ni 2,5 ~ 3%.
Rkwigisha kugoreka
Kubera ko ibyuma bya PCBs bifite ubushyuhe bwiza bwo gukwirakwiza nubushyuhe bwumuriro, ntibikunda guhinduka bitewe nubushyuhe buterwa.Bitewe nibi biranga ibyuma byibanze, PCB nizo guhitamo kwambere kubikoresho bitanga amashanyarazi bisaba guhinduranya cyane.
