A fagen allunan kewayawa na lantarki, don biyan ƙarin buƙatun samfur, ƙarin CCLs suna kwararowa cikin kasuwa.Menene CCL?Menene CCL mafi shahara kuma mai arha?Wataƙila ba za a mai da hankali ga ƙananan injiniyoyin lantarki da yawa ba.Anan, zaku koyi abubuwa da yawa game da CCL kuma zai taimaka don ayyukan ku na lantarki na gaba.
1. Ma'anar Copper Clad Laminate?
Copper Clad Laminate, wanda aka rage zuwa CCL, nau'in kayan tushe ne na PCBs.Tare da fiber gilashi ko takarda ɓangaren litattafan itace a matsayin kayan ƙarfafawa, CCL wani nau'i ne na samfur ta hanyar lamination tare da jan karfe a gefe ɗaya ko bangarorin biyu na kayan ƙarfafawa bayan an jika shi da guduro.
2. Rarraba CCLs?
Bisa ga ma'auni daban-daban, CCLs za a iya rarraba su zuwa sassa daban-daban:
• Dangane da ƙarfin injin CCL, Akwai m CCL (FR-4, CEM-1, da dai sauransu) da CCL mai sassauƙa.PCBs masu ƙarfi sun dogara da tsattsauran CCLs yayin da masu sassaucin ra'ayi na PCBs ke kan CCLs masu sassauƙa (PCBs masu ƙarfi suna kan duka CCLs masu tsauri da masu sassaucin ra'ayi CCLs).
• Dangane da kayan haɓakawa da tsarin, Akwai resin Organic CCL (FR-4, CEM-3, da dai sauransu), CCL ƙarfe-tushe, yumbu-base CCL da dai sauransu.
• Dangane da kauri na CCL Akwai daidaitaccen kauri CCL da CCL na bakin ciki.Na farko yana buƙatar kauri aƙalla 0.5mm yayin da na ƙarshen zai iya zama bakin ciki fiye da 0.5mm.An cire kauri daga kauri daga CCL.
• Dangane da nau'ikan kayan haɓakawa, Akwai gilashin fiber fiber tushe CCL (FR-4, FR-5), tushe CCL (XPC), fili CCL (CEM-1, CEM-3).
• Dangane da guduro mai shafa, Akwai resin epoxy CCL (FR-4, CEM-3) da Phenolic CCL (FR-1, XPC).
3. Wane irin CCL ake amfani da shi sosai?
Daga cikin samfuran fiberglass tushe tushe na samfuran CCL, FR-4 CCL suna taka muhimmiyar rawa.An yi amfani da ita sosai a cikin alluna iri-iri
Har zuwa yanzu, an ƙirƙira samfuran daban-daban dangane da FR-4 CCL kuma an haɓaka su saboda matakan aiki daban-daban kuma nau'ikan suna aiwatar da haɓakawa da haɓaka sannu a hankali.Babban samfuran da aka dogara da FR-4 CCL ana nuna su a cikin FR-4 na gama gari, Mid-Tg FR-4, High-Tg FR-4, siyarwar da ba ta da gubar FR-4, Halogen-free FR-4, Mid-Tg ( Tg150°C) halogen-free FR-4, High-Tg (Tg170°C) halogen-free FR-4,FR-4 CCL tare da babban yi ect ..
Bugu da kari, akwai High modules FR-4 jirgin, FR-4 jirgin tare da low coefficient na thermal fadadawa, FR-4 jirgin tare da low dielectric akai, High-CTI FR-4 jirgin, High-CAF FR-4 jirgin, High thermal -haɓakawa FR-4 jirgi don LED.
Bayan ƙoƙari da gogewa a cikin masana'antar PCB, PHILIFAST ya taka muhimmiyar rawa don ba da gudummawa ga mafi girman aiki a masana'antar masana'antar lantarki.
