Ma ke kahua o nā papa kaapuni uila, i mea e hoʻokō ai i ka makemake o nā huahana, ʻoi aku ka nui o nā CCL e kahe ana i ka mākeke.He aha ka CCL?He aha ka CCL kaulana a maʻalahi?ʻAʻole paha ia e noʻonoʻo no ka nui o nā ʻenekini uila uila.Maʻaneʻi, e aʻo nui ʻoe e pili ana iā CCL a he mea kōkua ia no kāu mau papahana uila e hiki mai ana.
1. Ka wehewehe o Copper Clad Laminate?
ʻO Copper Clad Laminate, i hoʻopau ʻia i ka CCL, he ʻano kumu kumu o nā PCB.Me ka fiber aniani a i ʻole ka pepa pulp lāʻau ma ke ʻano he mea hoʻoikaika, ʻo ka CCL kahi ʻano huahana ma o ka lamination me ke keleawe i ʻaʻahu ʻia ma kekahi ʻaoʻao a i ʻole nā ʻaoʻao ʻelua o ka mea hoʻoikaika ma hope o ka pulu ʻana i ka resin.
2. Hoʻokaʻawale i nā CCL?
E like me nā kūlana hoʻohālikelike like ʻole, hiki ke hoʻokaʻawale ʻia nā CCL i nā ʻano like ʻole:
• Ma muli o ka CCL mechanical rigidity, Aia nā CCL paʻa (FR-4, CEM-1, etc.) a me ka CCL flex.Pili nā PCB ʻoʻoleʻa i nā CCL ʻoʻoleʻa aʻo nā PCB flex ma nā CCL flex (ʻo nā PCB flex-rigid ma nā CCL paʻa a me nā CCL flex).
• Ma muli o ka insulation mea a me nā hale, Aia nā organic resin CCL (FR-4, CEM-3, etc.), metala-kumu CCL, ceramic-kumu CCL etc.
• Ma muli o ka mānoanoa CCL Aia ka mānoanoa ma'amau CCL a me ka lahilahi CCL.Pono ka mea mua ma ka liʻiliʻi he 0.5mm ka mānoanoa aʻo ka hope hiki ke lahilahi ma mua o 0.5mm.Hoʻokuʻu ʻia ka mānoanoa o ke keleawe mai ka mānoanoa CCL.
Ma muli o ka hoʻoikaika ʻana i nā ʻano mea, Aia nā aniani fiber lole kumu CCL (FR-4, FR-5), pepa kumu CCL (XPC), hui CCL (CEM-1, CEM-3).
• Ma muli o ka resin insulation i noi ʻia, Aia nā epoxy resin CCL (FR-4, CEM-3) a me Phenolic CCL (FR-1, XPC).
3. He aha ke ʻano o ka CCL i hoʻohana nui ʻia?
Ma waena o nā huahana CCL kumu lole fiberglass, pāʻani ʻo FR-4 CCL i kahi lula koʻikoʻi.Ua hoʻohana nui ʻia ka nalo ma nā ʻano papa he nui
A hiki i kēia manawa, ua hoʻokumu ʻia a hoʻomohala ʻia nā huahana like ʻole e pili ana i ka FR-4 CCL ma muli o nā pae hana like ʻole a ke hana nei nā ʻāpana i ka hana lohi a me ka hoʻomohala ʻana.Hōʻike ʻia nā huahana nui e pili ana i ka FR-4 CCL ma Common FR-4, Mid-Tg FR-4, High-Tg FR-4, Lead-free soldering FR-4, Halogen-free FR-4, Mid-Tg ( Tg150°C) halogen-noa FR-4, High-Tg (Tg170°C) halogen-noa FR-4,FR-4 CCL me ka hana ki'eki'e ect..
Eia kekahi, aia nā papa kiʻekiʻe modulus FR-4, FR-4 papa me ka haʻahaʻa haʻahaʻa o ka hoʻonui wela, FR-4 papa me ka mau dielectric haʻahaʻa, High-CTI FR-4 papa, High-CAF FR-4 papa, High thermal -conductivity FR-4 papa no LED.
Ma hope o nā hana a me ka ʻike i ka hana PCB, ua pāʻani ʻo PHILIFAST i kahi lula koʻikoʻi e hāʻawi i ka hana kiʻekiʻe ma ka ʻoihana hana uila.
