Umuringa shit lit core pcb kugirango ugaragaze uburyo bwo kwerekana hanze
Iyi ni igice cya 2umuringaPCB kurikumurikainganda. Icyuma cyicyuma cyacapwe inama yumuriro (McPcb), cyangwa PCB yubushyuhe, ni ubwoko bwa PCB ifite ibikoresho byicyuma nkishingiro ryayo yo gukwirakwiza ubushyuhe bwinama.

Icyuma core pcb cyangwa mcpcb
Icyuma core pcb (mcpcb) izwi nkibyuma byanyuma pcb cyangwa pcrmal pcb. Ubu bwoko bwa PCB bukoresha ibikoresho byicyuma aho kuba fr4 isanzwe, ubushyuhe bukabije bwinama.
As birazwiUbushyuhe bwakozwe ku Bunama kubera impamvu zimwe na zimwe ibice bya elegitoroniki mugihe cyo gukora. Icyuma cyohereza ibyuma bivuye mubuyobozi bwumuzunguruko no kugashyikiriza ibyuma byicyuma cyangwa ibyuma bikabora byinjira nibihe byingenzi byo kuzigama.
Muri PCB Multilayer PCB uzasangamo umubare wimyandikire yagabanijwe kuruhande rwibyuma. Kurugero, niba urebye kuri PCB 12 ya PCB, uzasangamo ibice bitandatu hejuru nibice bitandatu hepfo, hagati ni chare.
McPCB cyangwa icyuma core pcb izwi kandi nka icpb cyangwa ibyuma bya PCB, ims cyangwa byizewe cyangwa ibyuma byambukiranya ibyuma, PCB ya Clad PCB na PCBLE CCBs.
FCyangwa wowe kugirango usobanukirwe neza tuzakoresha ijambo ryicyuma Core PCB muriyi ngingo.
Imiterere yibanze yicyuma core pcb ikubiyemo ibi bikurikira:
Umuringa - 1oz.to 6oz. (Bisanzwe ni 1oz cyangwa 2oz)
Umuzunguruko
Umubano
Mask y'umucuruzi
Ubushyuhe bukabije cyangwa ubushyuhe bwa sink (list core igice)
Ibyiza kuri McPcb
Ubushyuhe
CEM3 cyangwa FR4 ntabwo ari byiza gukora ubushyuhe. Niba bishyushye
Itsinda ryakoreshejwe muri PCB rifite imishinga mibi kandi irashobora kwangiza ibice by'Inama y'Ubutegetsi ya PCB. Nibwo ibyuma bya core pcbs biza mubiryo.
McPCB ifite imyitwarire myiza yubushyuhe kugirango irinde ibice byangiritse.
Hkurya amacakubiri
Itanga ubushobozi bwiza bwo gukonjesha. Icyuma core PCB irashobora gutandukanya ubushyuhe muri ICC neza cyane. Igice cya none kigenda cyanduza ubushyuhe kumutwe wicyuma.
Igipimo gihamye
Itanga umutekano mwinshi kuruta ubundi bwoko bwa PCBS. Nyuma yubushyuhe bwahinduwe kuva kuri dogere 30 celsius kugeza kuri 140-150 dielsius, impinduka zigabanijwe rya aluminium yicyuma ni 2.5 ~ 3%.
REduce kugoreka
Kubera ko icyuma core pcbs zifite amashuri meza yubushyuhe nubucuruzi bwubushyuhe, ntibikunda guhindura bitewe nubushyuhe buteye inkunga. Bitewe nibi biranga ibyuma, PCBS ni uguhitamo kwambere kubisaba imbaraga zisaba guhindura hejuru.
