M'munda wa matabwa amagetsi ozungulira, kuti akwaniritse kufunika kwazinthu zambiri, ma CCL ochulukirapo akusefukira pamsika.Kodi CCL ndi chiyani?Kodi CCL yotchuka kwambiri komanso yotsika mtengo ndi iti?Itha kukhala yosayang'ana kwambiri mainjiniya ambiri amagetsi achichepere.Apa, muphunzira zambiri za CCL ndipo zidzakuthandizani tsogolo lanu lamagetsi.
1. Tanthauzo la Copper Clad Laminate?
Copper Clad Laminate, yofupikitsidwa ku CCL, ndi mtundu wazinthu zoyambira za PCB.Ndi magalasi ulusi kapena pepala zamkati zamatabwa ngati zolimbikitsira, CCL ndi mtundu wazinthu zopangidwa kudzera mu zokutira ndi zokutira zamkuwa mbali imodzi kapena mbali zonse za zinthu zolimbikitsira zitaviikidwa mu utomoni.
2. Gulu la CCLs?
Malinga ndi magawo osiyanasiyana, ma CCL amatha kugawidwa m'magulu osiyanasiyana:
• Malingana ndi CCL mechanical rigidity, Pali CCL yolimba (FR-4, CEM-1, etc.) ndi flex CCL.Ma PCB okhwima amadalira ma CCL okhwima pomwe ma PCB osinthika ali pa ma CCL osinthika (ma PCB okhazikika ali pa ma CCL olimba onse ndi ma CCL osinthika).
• Kutengera zinthu zotchinjiriza ndi kapangidwe kake, Pali organic resin CCL (FR-4, CEM-3, etc.), CCL-base CCL, ceramic-base CCL etc.
• Zotengera CCL makulidwe Pali muyezo makulidwe CCL ndi CCL woonda.Yoyamba imafuna makulidwe osachepera 0.5mm pomwe yomalizayo imatha kukhala yocheperako kuposa 0.5mm.Makulidwe a zojambulazo zamkuwa samaphatikizidwa ndi makulidwe a CCL.
• Malingana ndi kulimbikitsa mitundu ya zinthu, Pali magalasi a fiber nsalu maziko CCL (FR-4, FR-5), mapepala a CCL (XPC), pawiri CCL (CEM-1, CEM-3).
• Kutengera utomoni wopaka utoto, pali epoxy resin CCL (FR-4, CEM-3) ndi Phenolic CCL (FR-1, XPC).
3. Ndi CCL yotani yomwe imagwiritsidwa ntchito kwambiri?
Pakati pazinthu za CCL zopangira nsalu za fiberglass, FR-4 CCL imakhala ndi lamulo lofunikira kwambiri.Zakhala zikugwiritsidwa ntchito kwambiri mumitundu yambiri yamatabwa
Mpaka pano, zinthu zosiyanasiyana zozikidwa pa FR-4 CCL zapangidwa ndikupangidwa chifukwa cha magwiridwe antchito osiyanasiyana ndipo maguluwa akupanga chitukuko pang'onopang'ono.Zogulitsa zazikulu zochokera ku FR-4 CCL zimawonetsedwa mu Common FR-4, Mid-Tg FR-4, High-Tg FR-4, lead-free soldering FR-4, Halogen-free FR-4, Mid-Tg ( Tg150°C) yopanda halogen FR-4,High-Tg (Tg170°C) ya halogen FR-4,FR-4 CCL yokhala ndi magwiridwe antchito apamwamba ect..
Kuphatikiza apo, pali High modulus FR-4 board, FR-4 board yokhala ndi coefficient yocheperako yowonjezera kutentha, board ya FR-4 yokhala ndi dielectric yotsika, High-CTI FR-4 board, High-CAF FR-4 board, High thermal -conductivity FR-4 board ya LED.
Pambuyo pa khama ndi chidziwitso pakupanga PCB, PHILIFAST yakhala ikuchita lamulo lofunikira kuti lithandizire pakuchita bwino pamakampani opanga zamagetsi.
