Ufite gushidikanya, kuki substrate ya aluminium iruta FR-4?
Aluminium pcb ifite imikorere myiza yo gutunganya, irashobora kuba imbeho nubushyuhe bugoramye, gukata, gucukura nibindi bikorwa byo gutunganya, kugirango bitange imiterere nubunini butandukanye bwumuzunguruko. Ikibaho cyumuzunguruko cya FR4 gikunze gucika, kwiyambura nibindi bibazo, kandi biragoye kubitunganya. Kubwibyo, substrate ya aluminium isanzwe ikoreshwa mubikoresho bya elegitoroniki bikora cyane, nk'itara rya LED, ibikoresho bya elegitoroniki, ibikoresho by'amashanyarazi n'izindi nzego.
Nibyo, aluminium pcb nayo ifite ibibi bimwe. Kubera icyuma cyacyo, igiciro cya aluminium substrate kiri hejuru, kandi muri rusange gihenze cyane kuruta FR4. Mubyongeyeho, kubera ko substrate ya aluminiyumu itoroshye guhuza na pin yibikoresho rusange bya elegitoroniki, birakenewe kuvurwa bidasanzwe, nka metallisation, byongera igiciro cyo gukora. Byongeye kandi, urwego rwo kubika insimburangingo ya aluminiyumu rusaba kandi ubuvuzi bwihariye kugira ngo ubushyuhe bwogukwirakwiza bitagize ingaruka ku bwiza bwo kohereza ibimenyetso.
Usibye itandukaniro ryibiciro, hari nuburyo butandukanye hagati ya aluminium pcb na FR4 mubijyanye nimikorere nurwego rwo gusaba.
Mbere ya byose, substrate ya aluminium ifite imikorere myiza yo gukwirakwiza ubushyuhe, ishobora gukwirakwiza neza ubushyuhe butangwa ninama yumuzunguruko vuba. Ibi bituma aluminium substrate ikwiranye cyane nubushakashatsi bwimbaraga nyinshi, nkumucyo mwinshi, nkamatara ya LED, modules yingufu, nibindi. igishushanyo mbonera.
Icyakabiri, ubushobozi bwo gutwara bwa aluminium substrate ni nini, ikwiranye numuvuduko mwinshi hamwe nubushakashatsi bwumuzunguruko mwinshi. Mu gishushanyo mbonera cy’umuzunguruko mwinshi, icyuma kizana ubushyuhe, hamwe nubushyuhe bwo hejuru bwumuriro hamwe nubushuhe bwiza bwo gukwirakwiza ubushyuhe bwa aluminium substrate burashobora gukwirakwiza neza ubushyuhe, bityo bigatuma ubwizerwe n’umutekano byizunguruka. Ubushobozi bwo gutwara ubu bwa FR4 ni buto kandi ntibukwiriye gukoreshwa cyane, gushushanya imirongo myinshi.
Byongeye kandi, aluminium substrate yimikorere ya seisimike nayo iruta FR4, irashobora kurwanya neza ihungabana ryimashini no kunyeganyega, kubwibyo mumodoka, gari ya moshi nizindi nzego zishushanya ibyuma bya elegitoroniki, insimburangingo ya aluminiyumu nayo yakoreshejwe cyane. Muri icyo gihe, substrate ya aluminiyumu nayo ifite imikorere myiza yo kurwanya anti-electromagnetique, ishobora gukingira neza imiraba ya electromagnetique no kugabanya inzitizi zumuzunguruko.
Muri rusange, aluminium pcb ifite imikorere myiza yo gukwirakwiza ubushyuhe, ubushobozi bwo gutwara ibintu, imikorere ya seisimike hamwe n’umuvuduko ukabije wa electromagnetic irwanya FR4, kandi irakwiriye kubububasha bukomeye, ubwinshi bwinshi nubushakashatsi bwumurongo mwinshi. FR4 ikwiranye nubushakashatsi rusange bwa elegitoronike, nka terefone zigendanwa, mudasobwa zigendanwa nibindi bicuruzwa bya elegitoroniki. Igiciro cya aluminium substrate muri rusange kiri hejuru, ariko kubushakashatsi bukenewe cyane, guhitamo insimburangingo ya aluminium ni intambwe ikomeye.
Muncamake, aluminium pcb na FR4 birakwiriye muburyo butandukanye bwimikorere yumuzunguruko kandi bifite inyungu zabo nibibi. Mugihe uhitamo ibikoresho byubuyobozi bwumuzunguruko, birakenewe gupima ibintu bitandukanye ukurikije ibintu byihariye bisabwa hamwe nibisabwa kugirango uhitemo ibikoresho bikwiye.
