I kēia mau lā, nīnau pinepine kekahi mau hoaaloha i ka maikaʻi o ka conductivity mehana o ka substrate alumini, a pēlā aku, i kekahi mau nīnau e pili ana, ʻo ka mea aʻe: ʻo ka mea hana pcb metala nui e maopopo.

ʻO ka conductivity pahana o ka substrate aluminium ʻo ia kekahi o nā papa kuhikuhi koʻikoʻi e loiloi i ka maikaʻi o ka substrate alumini. ʻO nā kumu ʻē aʻe ʻelua ʻo ia ke kūpale kūpale a me ke kūpikipiki ʻana o ka substrate alumini. I kēia manawa, ʻo ka conductivity mehana o ka substrate alumini ma ka mākeke ʻo 2.00.1 ka nui. hiki ke ana ʻia i ka substrate alumini e nā mea kani, kahi e hoʻopili pono ai i ke kumukūʻai o ka substrate alumini. Ma ka laulā, ʻo ke kiʻekiʻe o ka conductivity mehana o ka substrate alumini, ʻo ke kiʻekiʻe ke kumukūʻai o ka substrate alumini. E like me ka nui o ka substrate alumini. , ʻaʻole hiki iā mākou ke nānā wale i ka conductivity thermal o ka substrate alumini. ʻO ka conductivity thermal, resistence thermal a me nā waiwai compressive o ka substrate alumini e hoʻoholo i nā waiwai o ka substrate alumini. ʻAʻole hoʻoholo ʻia e hoʻokahi mea.

ʻO ka ʻōlelo maʻamau, paʻa ka conductivity thermal o substrate alumini a ʻaʻole e loli me ka loli o nā kumu kūwaho. Hoʻoholo nui ʻia ka conductivity mehana e nā mea maka o ka substrate alumini. Inā hoʻohui ʻia nā mea conductivity mehana e like me ke keleawe a me ke kālā, ʻo ka ʻoi aku ka kiʻekiʻe o ka conductivity thermal o nā mea substrate alumini. ʻO ka conductivity thermal kahi mea nui o ke kino, kahi hapa paʻa o nā mea, a kū kaʻawale kāna conductivity mehana o ka mānoanoa a ʻāpana paha.

I kēia mau lā, conductive nā keramika, keleawe, a me nā mea ʻē aʻe. Eia nō naʻe, ma muli o nā pilikia kumu kūʻai, hoʻohana ʻia ka hapa nui o nā substrates alumini i ka mākeke, a ʻo ka conductivity mehana conductive o nā mea alumina substrates kahi mea e hopohopo ai nā mea āpau. o nā hiʻohiʻona o ka hana ʻoi aku ka maikaʻi. ʻO ka substrate alumini kahi mea hana keleawe-aluminika i hoʻopili ʻia me ka conductivity thermal maikaʻi, hoʻopili uila a me nā hana hana. ʻO ka conductivity waiwela o nā substrates alumini ma waena o 1.0, 1.5 a me 2.0, e hilinaʻi ana i ka noi no ka ukana.

ʻO ka mea i luna e pili ana i ka conductivity waiwela o ka substrate aluminika, lana koʻu manaʻo e makemake ʻoe; ʻO mākou he mea hao kumu hao pcb, ʻoluʻolu e nīnau
