Igice cya mbere: PC ya Aluminium ni iki?
Aluminium substrate ni ubwoko bwicyuma gishingiye kumuringa wambaye umuringa ufite imikorere myiza yo gukwirakwiza ubushyuhe.Mubisanzwe, ikibaho cyuruhande rumwe kigizwe nibice bitatu: urwego rwumuzunguruko (umuringa wumuringa), urwego rukingira, hamwe nicyuma fatizo.Kubisabwa murwego rwohejuru, hariho kandi ibishushanyo mbonera byombi bifite imiterere yumuzunguruko, urwego rukingira, aluminiyumu, urwego rukingira, hamwe n’umuzunguruko.Umubare muto wa porogaramu zirimo imbaho nyinshi, zishobora gukorwa muguhuza imbaho zisanzwe zisanzwe hamwe na aluminiyumu.
Substrate ya aluminiyumu imwe: Igizwe nigice kimwe cyurugero rwimikorere, ibikoresho byiziritse, hamwe na plaque ya aluminium (substrate).
Ibice bibiri bya aluminiyumu substrate: Harimo ibice bibiri byuburyo bwo kuyobora, ibikoresho bikingira, hamwe na plaque ya aluminium (substrate) byegeranye hamwe.
Ibice byinshi byacapwe bya aluminiyumu yumuzunguruko: Nibibaho byacapwe byumuzunguruko bikozwe no kumurika no guhuza ibice bitatu cyangwa byinshi byurwego rwimikorere yimyitwarire, ibikoresho bikingira, hamwe na plaque ya aluminium (substrate) hamwe.
Igabanijwe nuburyo bwo kuvura hejuru:
Ikibaho cyometseho zahabu (Zahabu yoroheje yoroheje, Imiti yimbuto ya shimi, isahani ya zahabu yatoranijwe)
Igice cya kabiri: Ihame ry'akazi rya Aluminium
Ibikoresho byingufu byashizwe hejuru kurwego rwumuzingi.Ubushyuhe butangwa nibikoresho mugihe cyo gukora bukorwa byihuse binyuze murwego rwo kubika ibyuma kugeza hasi, hanyuma bigakwirakwiza ubushyuhe, bikagera no kugabanuka kubikoresho.
Ugereranije na gakondo ya FR-4, insimburangingo ya aluminiyumu irashobora kugabanya ubushyuhe bwumuriro, bigatuma ikora neza cyane.Ugereranije na firime yuzuye ya ceramic, ifite kandi imiterere yubukanishi.
Byongeye kandi, aluminium substrate ifite ibyiza byihariye bikurikira:
- Kubahiriza ibisabwa na RoHs
- Guhuza neza nibikorwa bya SMT
- Gukoresha neza gukwirakwiza ubushyuhe bwumuriro mugushushanya kumashanyarazi kugirango ugabanye ubushyuhe bwimikorere ya module, wongere igihe cyo kubaho, wongere imbaraga zubwizerwe
- Kugabanuka mu guteranya ibyuma bishyushya hamwe nibindi byuma, harimo ibikoresho bya interineti yubushyuhe, bigatuma ibicuruzwa bito bito hamwe nibikoresho bigabanutse hamwe nigiciro cyo guterana, hamwe no guhuza imbaraga nimbaraga zo kugenzura.
- Gusimbuza ceramic substrate yoroheje kugirango ikorwe neza
Igice cya gatatu: Ibigize Substrates ya Aluminium
1. Inzira Yumuzingi
Inzira yumuzunguruko (mubisanzwe ikoresha amashanyarazi ya electrolytike yumuringa) yashizwemo kugirango ibe imizingo icapye, ikoreshwa muguteranya ibice no guhuza.Ugereranije na gakondo ya FR-4, hamwe n'ubugari bumwe n'ubugari bw'umurongo, aluminiyumu irashobora gutwara imigezi ihanitse.
2. Gukingira
Icyuma gikingira ni tekinoroji yingenzi muri aluminiyumu, ikora cyane cyane kubifata, kubika, no gutwara ubushyuhe.Inzira ya insuline ya aluminiyumu ninzitizi ikomeye yubushyuhe mumashanyarazi.Ubushuhe bwiza bwumuriro bwurwego rwimikorere byorohereza ikwirakwizwa ryubushyuhe butangwa mugihe cyibikorwa byigikoresho, biganisha ku bushyuhe buke bwo gukora, kongera ingufu za module, kugabanuka kwinshi, igihe kirekire, no gusohora ingufu nyinshi.
3. Icyuma Cyibanze
Guhitamo ibyuma kubishingiro byicyuma biterwa no gutekereza kubintu nka coefficente yicyuma cyo kwagura ubushyuhe, ubushyuhe bwumuriro, imbaraga, ubukana, uburemere, imiterere yubuso, nigiciro.
Igice cya kane: Impamvu zo Guhitamo Aluminium Substrates
1. Gukwirakwiza Ubushyuhe
Byinshi mu mpande zombi kandi zifite ibice byinshi bifite ubwinshi nimbaraga nyinshi, bigatuma ubushyuhe bugabanuka.Ibikoresho bisanzwe bya substrate nka FR4 na CEM3 ni imiyoboro idahwitse yubushyuhe kandi ifite insulire hagati, bigatuma ubushyuhe budahagije.Aluminium substrate ikemura iki kibazo cyo gukwirakwiza ubushyuhe.
Kwaguka k'ubushyuhe
Kwiyongera k'ubushyuhe no kugabanuka biranga ibikoresho, kandi ibintu bitandukanye bifite coefficient zitandukanye zo kwagura ubushyuhe.Ibibaho byanditse kuri Aluminiyumu bikemura neza ibibazo byo gukwirakwiza ubushyuhe, koroshya ikibazo cyo kwagura ibintu bitandukanye byubushyuhe bwibikoresho byubuyobozi, kunoza igihe kirekire no kwizerwa, cyane cyane mubikorwa bya SMT (Surface Mount Technology).
3. Igihagararo
Ibibaho byanditse kuri aluminiyumu biragaragara ko bihagaze neza mubijyanye nubunini ugereranije nibikoresho byanditse.Ihinduka ryibipimo byanditseho aluminiyumu cyangwa imbaho za aluminiyumu, zashyutswe kuva 30 ° C kugeza 140-150 ° C, ni 2.5-3.0%.
4. Izindi mpamvu
Ibibaho byanditse kuri Aluminiyumu bifite ingaruka zo gukingira, gusimbuza ibice byubutaka bwa ceramic, bikwiranye nubuhanga bwo kuzamura hejuru yubutaka, kugabanya ahantu heza h’ibibaho byacapwe, gusimbuza ibice nka sikeri kugira ngo byongere ubushyuhe bw’ibicuruzwa n’imiterere y’umubiri, kandi bigabanye ibiciro by’umusaruro n’umurimo.
