Ihiganwa rya PCB

MCPCB ni impfunyapfunyo ya Metal core PCBs, harimo PCB ya aluminium, PCB y'umuringa na PCB ishingiye ku cyuma.

Ubuyobozi bushingiye kuri aluminium nubwoko busanzwe. Ibikoresho fatizo bigizwe na aluminiyumu, bisanzwe FR4 n'umuringa. Igaragaza ubushyuhe bwumuriro ukwirakwiza ubushyuhe muburyo bukora neza mugihe gikonje. Kugeza ubu, PC ya Aluminium PCB ifatwa nkigisubizo cyimbaraga nyinshi. Ikibaho gishingiye kuri aluminiyumu kirashobora gusimbuza ikibaho gifatika ceramic, kandi aluminiyumu itanga imbaraga nigihe kirekire kubicuruzwa bidafite ishingiro.

Substrate yumuringa nimwe mubyuma bihenze cyane, kandi ubushyuhe bwayo bwumuriro buruta inshuro nyinshi kurenza iyitwa aluminium substrate. Irakwiriye gukwirakwizwa cyane nubushyuhe bwumurongo mwinshi, ibice byo mukarere bifite itandukaniro ryinshi mubushyuhe bwo hejuru kandi buke hamwe nibikoresho byitumanaho neza.

Ubushyuhe bwo gutwika ubushyuhe ni kimwe mu bice byingenzi bigize substrate yumuringa, bityo ubunini bwumuringa wumuringa ni m 35 m-280 m, bushobora kugera kubushobozi bukomeye bwo gutwara. Ugereranije na aluminium substrate, substrate y'umuringa irashobora kugera ku ngaruka nziza zo gukwirakwiza ubushyuhe, kugirango harebwe niba ibicuruzwa bihagaze neza.

Imiterere ya Aluminium PCB

Umuzunguruko wumuringa

Umuzunguruko wumuringa wumuzunguruko watejwe imbere kandi ushizwemo kugirango ube umuzenguruko wacapwe, substrate ya aluminiyumu irashobora gutwara umuyoboro muremure kuruta uburebure bwa FR-4 nubugari bumwe.

Gukingira

Icyuma gikingira ni tekinoroji yibanze ya aluminium substrate, ikina cyane cyane imirimo yo kubika no gutwara ubushyuhe. Aluminium substrate insulasiyo nini ninzitizi nini yubushyuhe mumashanyarazi. Nibyiza ko ubushyuhe bwumuriro bwurwego rwimikorere, nuburyo bwiza bwo gukwirakwiza ubushyuhe butangwa mugihe cyibikoresho, kandi nubushyuhe bwigikoresho,

Substrate

Ni ubuhe bwoko bw'icyuma tuzahitamo nk'icyuma gikingira?

Tugomba gusuzuma coefficente yo kwagura ubushyuhe, ubushyuhe bwumuriro, imbaraga, ubukana, uburemere, imiterere yubuso nigiciro cya substrate yicyuma.

Mubisanzwe, aluminiyumu ihendutse ugereranije n'umuringa. Ibikoresho bya aluminiyumu biboneka ni 6061, 5052, 1060 nibindi. Niba hari byinshi bisabwa kugirango ubushyuhe bwumuriro, ibikoresho byubukanishi, ibikoresho byamashanyarazi nibindi bintu bidasanzwe, amasahani yumuringa, ibyuma bidafite ingese, ibyuma hamwe nicyuma cya silikoni nabyo birashobora gukoreshwa.
