No ke aha e aluminika substrate pcb ? ʻO Yongmingsheng ʻoihana alumini mea hana substrate e pane i kēia nīnau.

ʻO Metal substrate kahi mea hao, akā hoʻokaʻawale ʻia mai ka laina e kahi papa insulate, ʻaʻole e uku ʻia ʻo Aluminium substrate kahi pā keleawe i hoʻohana ʻia i ke alumini ma ke ʻano he substrate, me ka hoʻopau wela maikaʻi. hoʻohana maʻamau i ka substrate alumini, i ka noi o nā kukui LED, no ka mea nui ka wela LED.

Inā ʻaʻole e hoʻopau ʻia ka wela i ka manawa, maʻalahi ka ʻōlinolino, a hoʻopau pū i ke kope. He metala ka Aluminum, me ka maikaʻi o ka conductivity mehana, hiki i nā lei kukui LED i hoʻouka ʻia i ka mea alumini ke hoʻopau koke i ka wela. he papa hoʻohaʻahaʻa, ʻaʻole conductive, inā conductive, ʻaʻohe ala e hoʻolālā ai i ke kaapuni ma luna.

ʻO ke kinikini substrate alumini ʻaoʻao ʻelua ma ka ʻaoʻao aluminium i ʻekolu mau papa, ma ke ʻano, ka laina laina (keleawe keleawe), a me ka papa hoʻohiehie a me ka waihona metala alumini. Aia kahi papa insulate ma waena o ka laina laina a me ka pcb base aluminika , no laila ʻaʻohe pōkole kaapuni.

ʻO nā substrate alumini kiʻekiʻe me nā papa pālua he mau papa kuʻina ma nā ʻaoʻao ʻelua, me kahi kumu alumini i waenakonu o ka papa. He laha ʻole nā ​​substrate alumini multilayer. ʻO nā kukui LED he substrate alumini ʻaoʻao hoʻokahi, a ua kau ʻia ka laina laina me LED. ʻAe ka papa aluminika i hope e hoʻopili maikaʻi me ka radiator e hoʻopau i ka wela.

ʻO ka papa hoʻohaʻahaʻa i ka substrate alumini ka mea nui a me ka ʻenehana nui o ka substrate alumini. ʻAʻole ia e pili wale i ka pepa keleawe, akā maikaʻi pū ka lawe wai ʻana. No ka mea ʻo ka papa hoʻohaʻahaʻa substrate alumini ka pale nui o ka conductivity thermal, inā ʻaʻole hiki iā ʻoe ke hoʻololi koke i ka wela o ka pepa keleawe i ka substrate alumini, he mea ʻole ka ʻaʻaina aluminika.

ʻO ka mea i luna aʻe ke kumu e pōkole ʻole ai ka substrate alumini, ke lana nei koʻu manaʻo i kēia ʻatikala iā ʻoe. Welina e kūkākūkā iā mākou!
