Emkhakheni wamabhodi esekethe ye-elekthronikhi, ukuze kuhlangatshezwane nesidingo esiningi somkhiqizo, ama-CCL amaningi agcwala emakethe.Iyini i-CCL?Iyiphi i-CCL edume kakhulu neshibhile?Kungase kungagxili konjiniyela abaningi bama-electronics abancane.Lapha, uzofunda okuningi nge-CCL futhi kuzosiza kumaphrojekthi akho e-electronics wesikhathi esizayo.
1. Incazelo ye-Copper Clad Laminate?
I-Copper Clad Laminate, efushanisiwe ibe yi-CCL, iwuhlobo lwezinto eziyisisekelo zama-PCB.Nge-glass fibre noma i-wood pulp paper njengento eqinisayo, i-CCL iwuhlobo lomkhiqizo ngokusebenzisa i-lamination ngendwangu yethusi ohlangothini olulodwa noma izinhlangothi zombili zezinto eziqinisayo ngemva kokucwiliswa ku-resin.
2. Ukuhlelwa kwama-CCL?
Ngokwamazinga ahlukene okuhlukanisa, ama-CCL angahlukaniswa ngezigaba ezahlukahlukene:
• Ngokusekelwe ku-CCL mechanical rigidity, Kukhona i-CCL eqinile (FR-4, CEM-1, njll.) kanye ne-flex CCL.Ama-PCB aqinile ancike kuma-CCL aqinile kuyilapho ama-PCB aguquguqukayo aku-CCL eguquguqukayo (ama-PCB aqinile aqinile akuwo womabili ama-CCL aqinile nama-CCL aguquguqukayo).
• Ngokusekelwe ezintweni ezifakwayo nezakhiwo, Kukhona i-organic resin CCL (FR-4, CEM-3, njll.), i-metal-base CCL, i-ceramic-base CCL njll.
• Ngokusekelwe kugqinsi lwe-CCL Kukhona ukujiya okujwayelekile kwe-CCL ne-CCL ezacile.Eyangaphambili idinga okungenani ukujiya okungu-0.5mm kuyilapho yakamuva ingaba izacile kuno-0.5mm.Ugqinsi lwe-copper foil alufakiwe kugqinsi lwe-CCL.
• Ngokusekelwe ezinhlotsheni zezinto ezibonakalayo eziqinisayo, Kunesisekelo sendwangu yengilazi ye-fiber cloth CCL (FR-4, FR-5), isisekelo sephepha CCL (XPC), i-CCL ehlanganisiwe (CEM-1, CEM-3).
• Ngokusekelwe ku-insulation resin esetshenzisiwe, Kukhona i-epoxy resin CCL (FR-4, CEM-3) ne-Phenolic CCL (FR-1, XPC).
3. Hlobo luni lwe-CCL olusetshenziswa kakhulu?
Phakathi kwemikhiqizo ye-CCL yendwangu ye-fiberglass, i-FR-4 CCL idlala umthetho obaluleke kakhulu.Isetshenziswe kabanzi ezinhlotsheni eziningi zamabhodi
Kuze kube manje, imikhiqizo ehlukene esekelwe ku-FR-4 CCL yenziwe futhi yathuthukiswa ngenxa yamazinga ahlukene okusebenza futhi izigaba zenza ukukhiqizwa nokuthuthukiswa kancane kancane.Imikhiqizo eyinhloko esekelwe ku-FR-4 CCL iboniswa ku-Common FR-4, Mid-Tg FR-4, High-Tg FR-4, i-lead-free soldering FR-4, Halogen-free FR-4, Mid-Tg ( I-Tg150°C) i-halogen-free FR-4,High-Tg (Tg170°C) i-halogen-free FR-4,FR-4 CCL esebenza kahle kakhulu.
Ngaphezu kwalokho, kukhona ibhodi le-High modulus FR-4, ibhodi le-FR-4 eline-coefficient ephansi yokwandisa okushisayo, ibhodi le-FR-4 eline-dielectric engaguquki, ibhodi le-High-CTI FR-4, ibhodi eliphezulu le-CAF FR-4, i-High thermal -conductivity FR-4 ibhodi LED.
Ngemuva kwemizamo nesipiliyoni ekukhiqizeni i-PCB, i-PHILIFAST idlale umthetho obalulekile wokufaka isandla ekusebenzeni okuphezulu embonini yokukhiqiza ugesi.
