PCB ya aluminium ya PCB ifite amazina menshi, kwambika aluminium, aluminium PCB, icyuma cyanditseho icyapa cyumuzunguruko (MCPCB), PCB itwara ubushyuhe bwa PCB, nibindi. na dielectric ikoreshwa mubisanzwe Ni inshuro 5 kugeza 10 zubushyuhe bwumuriro wikirahuri gisanzwe cya epoxy, kandi icyerekezo cyo guhererekanya ubushyuhe bwa kimwe cya cumi cyubugari bukora neza kuruta PCB gakondo.Reka twumve ubwoko bwa PCB aluminium substrate hepfo.

1. Imiterere ya aluminiyumu yoroheje

Kimwe mubikorwa bigezweho mubikoresho bya IMS ni dielectrics yoroheje.Ibi bikoresho birashobora gutanga amashanyarazi meza, guhindagurika hamwe nubushyuhe bwumuriro.Iyo ushyizwe mubikoresho bya aluminiyumu byoroshye nka 5754 cyangwa ibisa nayo, ibicuruzwa birashobora gukorwa kugirango bigere kumiterere itandukanye, bishobora gukuraho ibikoresho bihenze byo gutunganya, insinga hamwe nu murongo.Nubwo ibyo bikoresho byoroshye, byashizweho kugirango byunamye kandi bigume mu mwanya wabyo.

2. Kuvanga aluminium aluminium substrate
Mu miterere ya "hybrid" IMS, "sub-component" yibintu bitari ubushyuhe bitunganyirizwa mu bwigenge, hanyuma PCBs ya Amitron Hybrid IMS PCBs ihujwe na substrate ya aluminium hamwe nibikoresho byubushyuhe.Imiterere ikunze kugaragara cyane ni ibice 2 cyangwa 4 byo guteranya bikozwe muri gakondo ya FR-4, ishobora guhuzwa na substrate ya aluminium hamwe na termoelektrike kugirango ifashe gukwirakwiza ubushyuhe, kongera ubukana, no gukora nkingabo.Izindi nyungu zirimo:
1. Igiciro gito ugereranije nibikoresho byose bitwara ubushyuhe.
2. Tanga imikorere myiza yumuriro kuruta ibicuruzwa bisanzwe FR-4.
3. Ubushyuhe buhenze hamwe nintambwe zijyanye no guterana birashobora kuvaho.
4. Irashobora gukoreshwa mubikorwa bya RF bisaba ibiranga igihombo cya RF kurwego rwa PTFE.
5. Koresha idirishya ryibigize muri aluminiyumu kugirango uhuze ibice byacukuwe, byemerera abahuza ninsinga kunyuza umuhuza binyuze muri substrate mugihe cyo gusudira impande zose kugirango ukore kashe idakenewe gasketi idasanzwe cyangwa izindi adaptate zihenze.

Bitatu, byinshi bya aluminium substrate
Mu isoko ryo gutanga amashanyarazi menshi, IMS PCBs igizwe nabantu benshi ba dielectrics.Izi nyubako zifite urwego rumwe cyangwa nyinshi zumuzingi zashyinguwe muri dielectric, kandi viasi zimpumyi zikoreshwa nka vias yumuriro cyangwa inzira yerekana ibimenyetso.Nubwo igishushanyo mbonera kimwe gihenze kandi ntigikora neza kugirango cyohereze ubushyuhe, bitanga igisubizo cyoroshye kandi cyiza cyo gukonjesha kubishushanyo mbonera.
Bane, unyuze mu mwobo aluminium substrate
Muburyo bugoye cyane, urwego rwa aluminiyumu rushobora gukora "intangiriro" yimiterere yubushyuhe bwinshi.Mbere yo kumurika, aluminiyumu amashanyarazi kandi yuzuye dielectric mbere.Ibikoresho by'ubushyuhe cyangwa ibice bishobora gushyirwa kumpande zombi za aluminium ukoresheje ibikoresho bifata ubushyuhe.Iyo bimaze kumurikirwa, inteko irangiye isa na gakondo ya aluminiyumu isanzwe ikoresheje gucukura.Bishyizwe mu mwobo unyura mu cyuho cya aluminium kugirango ukomeze amashanyarazi.Ubundi, intandaro yumuringa irashobora kwemerera guhuza amashanyarazi no guhinduranya insina.
