Makemake ʻoe e ʻike i ka ʻokoʻa ʻekolu ma waena o ka fiberglass a me ka substrate alumini? ʻOihana ʻo Yongmingsheng ʻenehana  hale hana aluminika pcb no ʻoe e wehewehe.

He aha ka fiberglass

ʻO Fiberglass Insulation Board (FR-4), ʻo ia hoʻi ʻo Fiberglass Insulation Board, hana ʻia i nā mea fiberglass a me nā mea i hoʻohui ʻia me ke kūpaʻa wela kiʻekiʻe. ʻAʻohe ona asbestos e hoʻopōʻino ai i ke olakino kanaka.

ʻO nā mea maikaʻi o ke kīʻaha

ʻO ka papa fiber he waiwai mechanical kiʻekiʻe loa a me ke kūpaʻa uila, akā maikaʻi pū ka wela a me ke kūpikū, a me ka hana maikaʻi. Hoʻohana maʻamau i ka palolo a me ka hana ʻana i nā mīkini.

Noi o ka papa aniani puluniu:

1. ʻOihana kūkulu.

2. ʻOihana kemika.

3. ʻOihana kaʻaahi a me nā ʻoihana kaʻaahi.

ʻO nā ʻano pilikino maikaʻi, no laila ua hoʻohana ʻia ia i nā hale radar. He mea anticorrosive maikaʻi a hoʻohana nui ʻia ia i ka ʻoihana kemika. Loaʻa ka maikaʻi o ka palaka aniani o ka plasticity ikaika.

He aha ka substrate alumini

ʻO ke kuhumu aluminika kahi ʻano o ka papa kila keleawe keleawe me ka hana dissipation wela maikaʻi. ʻO ka maʻamau, hoʻokumu ʻia kahi panela ʻekolu o nā ʻāpana o ke ʻano, ʻo ia ka papa kaapuni (keleawe keleawe), ka papa hoʻohaʻahaʻa a me ka pae kumu hao.

Nā pōmaikaʻi o ka substrate alumini

ʻOi aku ka maikaʻi o ka hoʻopau wela ma mua o ke ʻano FR-4 maʻamau. ʻO ka dielectric i hoʻohana ʻia he ʻelima a he ʻumi mau manawa ke ʻano conductive e like me ke aniani epoxy maʻamau a he ʻumi hapaʻumi ka mānoanoa. ʻOi aku ka maikaʻi o ka papa kuhikuhi hoʻoili wela ma mua o PCB paʻa paʻa. ʻo ke kaupaona keleawe haʻahaʻa ma mua o ka mea i hōʻike ʻia i ka IPC paipai kiʻi hiki ke hoʻohana ʻia.

Hoʻohana o ka substrate alumini

1. lako pono leo

2. lako pono uila

3. Nā pono uila

4. ʻOihana pono hana keʻena: hoʻokele kaʻa

5. Ke kaʻa

6. Kamepiula

7. Module mana

ʻEkolu ʻokoʻa nui ma waena o fiberglass a me substrate alumini

1. Kumukūʻai

ʻO nā mea nui o ke kukui kukui uila LED: ka papa kaapuni, ka puʻukū LED a me ka mana hoʻokele. Hoʻokaʻawale ʻia ka papa kaapuni hoʻohana ʻia i ʻelua mau ʻano: papa substrate aluminika a me ka papa aniani aniani.

ʻO ka hoʻohālikelike kumukūʻai ma waena o ka papa aniani a me ka substrate alumini e hōʻike ana he ʻoi aku ke kumukūʻai o ke kumukūʻai o ka papa aniani aniani, akā ʻoi aku ka maikaʻi o ka hana o ka substrate alumini ma mua o ka papa fiber fibre.

2. Kaʻina hana

Hiki ke hoʻokaʻawale ʻia ka papa aniani aniani i loko o ka papa pālua keleawe pepa pālua, ka pahu paʻalima keleawe pepa a me ka pale pale pale keleawe hoʻokahi e like me nā mea like ʻole a me nā ʻenehana hana. ʻOiaʻiʻo, e loaʻa i nā papa aniani aniani i nā ʻano mea like ʻole nā ​​kumu kūʻai like ʻole. ʻO nā mea like ʻole a me nā ʻenehana ʻaʻole i like ka uku o ka papa aniani aniani. ʻAʻole maikaʻi ka lama kukui LED e hoʻohana ana i ka papa aniani aniani e like me ke kukui kukui LED e hoʻohana ana i ka substrate aluminium i ka hoʻopau wela.

3. Hana

E like me kā mākou āpau, he maikaʻi maikaʻi ka hoʻopau ʻana o ka aluminika substrate, a ʻoi aku ka maikaʻi o kāna hana ʻoi aku ka maikaʻi ma mua o ka papa aniani aniani, no ka mea ʻo ka substrate alumini kahi conductive thermal maikaʻi he mea nui ka substrate alumini i ke kahua o nā kukui LED a me nā ipukukui. .

No laila ʻo ia nā ʻokoʻa ʻekolu ma waena o ka fiberglass a me ka substrate alumini. He mea hana ʻoihana ʻo Huizhou Yongmingsheng Technology Co., Ltd. i kahi ʻenehana aluminika. Lana koʻu manaʻo i kēia ʻatikala hiki iā ʻoe ke hāʻawi iā ʻoe i kahi ʻike no ka substrate alumini.
