He aha nā ʻano o ka PCB alumini substrates o nā mea hana pcb

I kēia manawa, ʻelua ʻaoʻao ka substrate alumini LED maʻamau, hoʻohana ʻia ka ʻaoʻao keʻokeʻo no ka wili ʻana i nā pine LED, a ʻo ka ʻaoʻao ʻē aʻe e hōʻike ana i ke kala maoli o ka alumini.Hoʻopili nā ʻāpana thermally conductive me kekahi i kekahi.ʻO ka ʻōlelo maʻamau, ʻo kahi papa hoʻokahi he ʻano papa ʻekolu.ʻOiaʻiʻo, pono e ʻike ka poʻe ʻike iā ia, a ma ka hoʻomaopopo ʻana i kēia mau mea hiki ke koho maikaʻi ʻia a hoʻohana ʻia.ʻO ka substrate alumini he laminate keleawe i hoʻopaʻa ʻia me ka hana hoʻopau wela maikaʻi.E nānā kākou i nā ʻano o ka PCB alumini substrates o nā mea hana pcb.

Palena Aluminum Hiki

ʻO kekahi o nā mea hou i nā mea IMS he dielectrics maʻalahi, nona ka insulation uila maikaʻi loa, ka maʻalahi a me ka conductivity thermal.Ke hoʻohana ʻia i ka alumini maʻalahi, hiki ke hana ʻia ka huahana i nā ʻano ʻano like ʻole a me nā kihi, e hoʻopau ana i ka pono o nā kaula wili a me nā mea hoʻohui.ʻO ka mea maʻamau he mau ʻāpana ʻelua a ʻehā paha i hana ʻia me ka FR-4 maʻamau, i hoʻopaʻa ʻia i kahi substrate alumini me kahi dielectric thermal e kōkua i ka hoʻopau ʻana i ka wela, hoʻonui i ka ʻoʻoleʻa a hana i pale.Ma ka mākeke mana hana kiʻekiʻe, aia kēia mau hale i hoʻokahi a ʻoi aku paha nā ʻāpana o ka circuitry i kanu ʻia i loko o kahi dielectric, me nā vias makapō i hoʻohana ʻia e like me nā ala wela a i ʻole nā ​​ala hōʻailona.

Ma o ka puka alumini substrate

I loko o nā hale paʻakikī, hiki i kahi papa o ka alumini ke hana i ka "core" o ka multilayer thermal structure, i hoʻopaʻa mua ʻia a hoʻopiha ʻia me kahi dielectric ma mua o ka lamination.Hoʻopili ʻia nā puka ma waena o nā āpau i ka alumini no ka mālama ʻana i ka hoʻokaʻawale uila, i manaʻo ʻia he huaʻōlelo umbrella no nā PCB i hoʻolaʻa ʻia i ka ʻoihana LED ma muli o kāna conductivity thermal maikaʻi.
ʻO nā mea āpau, ʻo nā ʻano o ka PCB alumini substrates o nā mea hana pcb e komo pū me nā substrate alumini maʻalahi a me nā substrates alumini puka puka.No nā noi, aia nā hoʻolālā ʻaoʻao ʻelua o ka papa kaapuni, ka papa insulating, ka base aluminika, ka papa insulating, a me ka hoʻolālā ʻāpana kaapuni.He liʻiliʻi nā noi he mau papa multi-layer, hiki ke laminated me nā papa multi-layer maʻamau me nā papa insulating a me nā substrate alumini.ʻO nā substrate alumini ka hoʻopau wela maikaʻi loa, ka machinability maikaʻi, ke kūpaʻa dimensional a me nā waiwai uila, a hoʻohana nui ʻia i nā kaʻa hoʻohui hybrid, nā kaʻa, nā keʻena ʻoihana, nā lako uila nui, nā lako mana a me nā kula ʻē aʻe.
