Hoʻolauna o MCPCB

ʻO MCPCB ka hoʻopōkole o nā PCB kumu nui, e like me ka PCB e pili ana i ka aluminika, PCB e pili ana i ke keleawe a me ka PCB hoʻokumu hao.

ʻO ka papa ma muli o Aluminium ka ʻano maʻamau. ʻO nā mea kumu o ka aluminika kumu, FR4 maʻamau a me ke keleawe. Hoʻohālikelike ia i kahi papa ʻaila pumehana e hoʻopau i ka wela i kahi hana kūpono keu ka hoʻoluʻolu. I kēia manawa, ʻike ʻia ʻo PCB Ma muli o ka aluminika e like me ka hopena i ka mana kiʻekiʻe. Hiki i ka papa aluminika ke pani i ka papa pālolo ma frangible, a hāʻawi ka aluminika i ka ikaika a me ka paʻa i kahi huahana i hiki ʻole i nā kumu pālolo.

ʻO ka mea hoʻowahāwahā keleawe kekahi o nā substrate mea hao kiʻekiʻe loa, a ʻoi aku ka maikaʻi o kāna conductivity mehana ma mua o nā mea i hoʻoneʻe ʻia a me nā mea hao hao. He kūpono ia no ka hoʻopau wela wela kiʻekiʻe o nā kaapuni alapine kiʻekiʻe, nā ʻāpana i nā wahi me ka loli nui i ke kiʻekiʻe a me ka haʻahaʻa a me nā pono hana kamaʻilio.

ʻO ka pale hoʻohaʻahaʻa wela kekahi o nā ʻāpana o ka mea keleawe substrate, no laila ʻo ka mānoanoa o ka pepa kila keleawe 35 m-280 m, ka mea hiki ke hoʻokō i ka hiki ke hāpai i kēia manawa. Ke hoʻohālikelike ʻia me ka substrate alumini, hiki i ka substrate keleawe ke hoʻokō i ka hopena dissipation wela ʻoi aku ka maikaʻi, i mea e hōʻoia ai i ke kūpaʻa o ka huahana.

'Ole o Aluminium PCB

Kaapuni keleawe kolo

Hoʻomohala ʻia ka papa keleawe keleawe a kālai ʻia e hana i kahi kaapuni i paʻi ʻia, hiki i ka substrate alumini ke hāpai i kahi ʻoi aku ke kiʻekiʻe ma mua o ka FR-4 mānoanoa like a me ka laulā like like.

Pākuʻi Insulate

ʻO ka papa hoʻoneʻe ka ʻenehana nui o ka substrate alumini, kahi e hoʻokani nui i nā hana o ka hoʻoneʻe a me ka conduction wela. ʻO ka papa kuina insulated aluminika ka pale nui wela ma ka hanana mana mana. ʻO ka ʻoi aku o ka maikaʻi o ka conductivity thermal o ka layer insulate, ʻoi aku ka maikaʻi o ka hoʻolaha ʻana i ka wela i hana ʻia i ka wā o ka hana, a ʻo ka haʻahaʻa o ka mahana o ka hāmeʻa.

Pākuʻi hao

He aha ke ʻano o ka hao e koho ai mākou ma ke ʻano he mea hoʻoheheʻe keleawe substrate?

Pono mākou e noʻonoʻo i ka coefficient hoʻonui hoʻonui thermal, conductivity thermal, ikaika, paakiki, kaumaha, ʻilikai a me ke kumukūʻai o ka mea hao.

ʻO ka maʻamau, ʻoi aku ka liʻiliʻi o ka aluminika ma mua o ke keleawe. Loaʻa nā mea aluminiia he 6061, 5052, 1060 a pēlā aku. Inā nui nā koi no ka conductivity mehana, nā pono mechanical, nā pono uila a me nā waiwai kūikawā ʻē aʻe, nā pā keleawe, nā papa kila kila, nā pā hao a me nā pā kila silikone.
