Sebakeng sa mapolanka a potoloho ea elektronike, e le ho finyella tlhokahalo e eketsehileng ea lihlahisoa, li-CCL tse ngata li ntse li phalla 'marakeng.CCL ke eng?CCL e tsebahalang haholo le e theko e tlase ke efe?E kanna ea se ke ea tsepamisa maikutlo ho lienjineri tse ngata tse nyane tsa elektroniki.Mona, o tla ithuta ho hongata ka CCL mme e tla thusa mererong ea hau ea kamoso ea elektroniki.
1. Tlhaloso ea Copper Clad Laminate?
Copper Clad Laminate, e khutsufalitsoeng ho CCL, ke mofuta oa thepa ea motheo ea PCBs.Ka fiber ea khalase kapa pampiri ea makhasi a lehong e le lintho tse matlafatsang, CCL ke mofuta oa sehlahisoa ka lamination e nang le seaparo sa koporo ka lehlakoreng le leng kapa mahlakore ka bobeli a thepa e matlafatsang ka mor'a ho kolobisoa ka resin.
2. Khethollo ea li-CCL?
Ho latela maemo a fapaneng a mekhahlelo, li-CCL li ka aroloa ka mekhahlelo e fapaneng:
• Ho itšetlehile ka CCL mechanical rigidity, Ho na le CCL e thata (FR-4, CEM-1, joalo-joalo) le flex CCL.Li-PCB tse thata li ipapisitse le li-CCL tse thata ha li-PCB tse tenyetsehang li le ho li-CCL tse tenyetsehang (li-PCB tse flex-rigid li ho li-CCL tse thata le li-CCL tse tenyetsehang).
• Ho ipapisitsoe le thepa le meaho, Ho na le organic resin CCL (FR-4, CEM-3, joalo-joalo), CCL-base CCL, ceramic-base CCL joalo-joalo.
• Ho ipapisitsoe le botenya ba CCL Ho na le botenya bo tloaelehileng ba CCL le CCL e tšesaane.Ea pele e hloka bonyane botenya ba 0.5mm ha ea morao e ka ba tšesaane ho feta 0.5mm.Botenya ba foil ea koporo bo qheletsoe ka thoko ho botenya ba CCL.
• Ho itšetlehile ka mefuta ea lisebelisoa tse matlafatsang, Ho na le khalase ea lesela la khalase ea CCL (FR-4, FR-5), setsi sa pampiri sa CCL (XPC), motsoako oa CCL (CEM-1, CEM-3).
• Ho itšetlehile ka resin e sebelisitsoeng ea ho kenya letsoho, Ho na le epoxy resin CCL (FR-4, CEM-3) le Phenolic CCL (FR-1, XPC).
3. Ke mofuta ofe oa CCL o sebelisoang haholo?
Har'a lihlahisoa tsa CCL tsa masela a fiberglass, FR-4 CCL e bapala molao oa bohlokoa haholo.E sebelisitsoe haholo mefuteng e mengata ea mapolanka
Ho fihlela joale, lihlahisoa tse fapaneng tse ipapisitseng le FR-4 CCL li se li hlahisitsoe le ho ntlafatsoa ka lebaka la maemo a fapaneng a ts'ebetso mme mekhahlelo e ntse e tsoela pele butle butle le nts'etsopele.Lihlahisoa tse ka sehloohong tse thehiloeng ho FR-4 CCL li hlahisoa ka 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-free FR-4,High-Tg (Tg170°C) halogen-free FR-4,FR-4 CCL e nang le tshebetso e phahameng ect..
Ntle le moo, ho na le boto e Phahameng ea modulus FR-4, boto ea FR-4 e nang le coefficient e tlase ea katoloso ea mocheso, boto ea FR-4 e nang le dielectric kamehla, High-CTI FR-4 board, High-CAF FR-4 board, High-thermal board. -conductivity FR-4 boto bakeng sa LED.
Ka mor'a boiteko le phihlelo ea ho etsa PCB, PHILIFAST e na le molao oa bohlokoa oa ho kenya letsoho mosebetsing o phahameng oa indasteri ea tlhahiso ea lisebelisoa tsa elektronike.
