Lawe ka ʻenehana ʻo Yongmingsheng ʻenehana alumini pcb iā ʻoe e hoʻomaopopo i ka hana o ka pcb alumini.

ʻO ka aluminika pcb, kahi ʻano mea maka, kahi ʻano o ka papa kila keleawe keleawe keleawe me ka hana hoʻoliʻiliʻi wela maikaʻi. He pepa ia i hana ʻia i ka lole uila fiberglass a i ʻole nā ​​mea i hoʻoikaika ʻia i hoʻoiho ʻia i loko o ke kēpau, resin hoʻokahi a me nā ʻāpana adhesive insulate āpau, uhi ʻia ʻelua a ʻelua paha ʻaoʻao me ka pepa keleawe a hana ʻia e kaomi wela. Kapa ʻia ia kapa kila keleawe lamineka aluminika pcb, kuhi ʻia e like me ke ʻano o ka papa keleawe.

Nā waiwai o ka alumini pcb

Hana maikaʻi loa 1.excusive heat

ʻO ka aluminika papa keleawe pepa pahupaʻiwi ka hana dissipation wela maikaʻi loa, ʻo ia ke ʻano poʻokela ʻoi loa o kēia ʻano pā. ʻAʻole hiki i ka PCB ke hana me ia ke pale wale aku i ka mahana hana o nā mea a me ka pcb i hoʻouka ʻia i luna mai ka piʻi ʻana, akā wikiwiki pū emit i ka wela i hoʻokumu ʻia e nā mea hoʻonui i ka mana, nā mea mana kiʻekiʻe a me nā mea hoʻololi kaapuni nui.

Hoʻohui ʻia, no ka liʻiliʻi o ka liʻiliʻi, kaupaona māmā (2.7g / cm³), anti-oxidation, ʻoi aku ka liʻiliʻi o ke kumukūʻai, no laila ua lilo ia i mea hoʻohana nui ʻia e ka mea hao keleawe metala, ka nui o kahi pā hui. ʻo ka aluminika pcb saturated thermal resistive he 1.10 ℃ / W, ʻo 2.8 ℃ / W ke kūpale ʻana, kahi e hoʻomaikaʻi maikaʻi ai i ka uea keleawe fuse o kēia manawa.

2. hoʻonui i ka pono a me ka maikaʻi o ka mīkini ʻana

ʻO ka pāpale keleawe keleawe i loaʻa ka ikaika mechanical a me ka paʻakikī, ʻoi aku ka maikaʻi ma mua o ke ʻano resin paʻa paʻa keleawe papa pā a me ka pcb pālolo. ʻo ia pcb.

Hoʻohui ʻia, he pālahalaha maikaʻi ka pcb alumini. Hiki ke hoʻohana ʻia no ka hammering, riveting a me nā hana ʻaha ʻē aʻe ma ka pcb a i ʻole ke kūlou ʻana a wili ʻana ma ka ʻāpana pili ʻole o ka PCB i hana ʻia mai ia mea. ʻaʻole hiki i ka pā ʻaʻahu.

3. ʻO ke kūpaʻa dimensional kiʻekiʻe

ʻO ka hoʻonui hoʻomehana (kūpaʻa dimensional) kahi pilikia no nā ʻano pā keleawe āpau, keu hoʻi ka hoʻonui ʻana o ka mehana i ka ʻaoʻao mānoanoa o ka pā (Z axis), e pili ana i ka maikaʻi o nā lua metallization a me nā kaapuni. ʻO ke kumu nui ka linear ʻokoʻa ka coefficient o ka pā, e like me ke keleawe, a me ka coefficient linear hoʻonui o ka epoxy aniani puluniu lole pcb he 3.

ʻO ka laha hoʻonui ākea ma waena o nā mea ʻelua he nui loa, i hiki ai ke alakaʻi maʻalahi i ka ʻokoʻa o ka hoʻonui ʻana o ka pcb, a laila ka hopena o ka uha a me ka luku ʻia ʻana o nā kaula keleawe a me nā lua metallization. ʻoi aku ka liʻiliʻi ma mua o ka pcb resin āpau. No laila, kokoke i ka coefficient linear hoʻonui o ke keleawe, kahi mea pono e hōʻoia i ka maikaʻi a me ka hilinaʻi o ke kaapuni paʻi.

No laila ʻo ia ka hana o ka pcb alumini. ʻO Yongmingsheng kahi mea hoʻolako ʻoihana pcb alumini. Manaʻolana i kēia ʻatikala pono ʻoe e kōkua, aloha i kēlā me kēia e kūkākūkā.
