Kwintsimi yeebhodi zeesekethe ze-elektroniki, ukuze kuhlangatyezwane neemfuno ezininzi zemveliso, ii-CCL ezininzi zikhukula kwimarike.Yintoni i-CCL?Yeyiphi eyona CCL idumileyo netshiphu?Isenokungagxininiswa kwiinjineli ezininzi ze-elektroniki ezincinci.Apha, uya kufunda okuninzi malunga ne-CCL kwaye iya kuba luncedo kwiiprojekthi zakho ze-elektroniki zexesha elizayo.
1. Inkcazo yeCopper Clad Laminate?
I-Copper Clad Laminate, efinyeziweyo kwi-CCL, luhlobo lwezinto ezisisiseko zeePCB.Ngefiber yeglasi okanye iphepha le-pulp yeplanga njengezinto zokuqinisa, i-CCL luhlobo lwemveliso ngokusebenzisa i-lamination kunye nentsimbi yobhedu ngapha nangapha okanye kumacala omabini ezinto zokuqinisa emva kokuba zifakwe kwi-resin.
2. Ukuhlelwa kwee-CCL?
Ngokwemigangatho yokuhlela eyahlukeneyo, ii-CCLs zinokuhlelwa ngokweendidi ezahlukeneyo:
• Ngokusekelwe kwi-CCL mechanical rigidity, Kukho i-CCL eqinile (FR-4, CEM-1, njl.) kunye ne-flex CCL.Ii-PCB eziqinileyo zixhomekeke kwii-CCL ezomeleleyo ngelixa ii-PCB eziguquguqukayo zikwi-CCL eziguquguqukayo (ii-PCB eziguquguqukayo zikuzo zombini ii-CCL eziqinileyo kunye nee-CCL eziguqukayo).
• Ngokusekwe kwi-insulation material kunye nezakhiwo, Kukho i-organic resin CCL (FR-4, CEM-3, njl.), i-metal-base CCL, i-ceramic-base CCL njl.
• Ngokusekwe kubungqingqwa be-CCL Kukho ukutyeba okusemgangathweni kwe-CCL kunye ne-CCL ebhityileyo.Eyangaphambili ifuna ubuncinci be-0.5mm ubukhulu ngelixa umva unokuba mncinci kune-0.5mm.Ukutyeba kwefoyile yobhedu akubandakanywanga kubunzima beCCL.
• Ngokusekelwe kwiintlobo zezinto eziqiniswayo, Kukho isiseko se-glass fiber cloth CCL (FR-4, FR-5), isiseko sephepha CCL (XPC), i-CCL edibeneyo (CEM-1, CEM-3).
• Ngokusekelwe kwi-resin esetyenzisiweyo yokugquma, Kukho i-epoxy resin CCL (FR-4, CEM-3) kunye ne-Phenolic CCL (FR-1, XPC).
3. Loluphi uhlobo lwe-CCL olusetyenziswa ngokubanzi?
Phakathi kweemveliso ze-CCL ze-fiberglass, i-FR-4 CCL idlala umgaqo obaluleke kakhulu.Isetyenziswe ngokubanzi kwiindidi ezininzi zeebhodi
Ukuza kuthi ga ngoku, iimveliso ezahlukeneyo ezisekelwe kwi-FR-4 CCL zenziwe zaza zaphuhliswa ngenxa yamanqanaba ahlukeneyo okusebenza kwaye iindidi ziqhuba ukuveliswa kunye nophuhliso ngokuthe ngcembe.Iimveliso eziphambili ezisekelwe kwi-FR-4 CCL ziboniswa kwi-Common FR-4, Mid-Tg FR-4, High-Tg FR-4, i-Lead-free soldering FR-4, i-Halogen-free FR-4, i-Mid-Tg. Tg150°C) halogen-free FR-4,High-Tg (Tg170°C) halogen-free FR-4,FR-4 CCL with high performance ect..
Ukongeza, kukho ibhodi ye-High modulus FR-4, ibhodi ye-FR-4 ene-coefficient ephantsi yokwandiswa kwe-thermal, ibhodi ye-FR-4 ene-dielectric ephantsi rhoqo, i-High-CTI FR-4 ibhodi, i-High-CAF FR-4 ibhodi, i-High thermal -conductivity FR-4 ibhodi ye-LED.
Emva kwemizamo kunye namava kwimveliso ye-PCB, i-PHILIFAST idlale umthetho obalulekileyo wokufaka isandla ekusebenzeni okuphezulu kwishishini lokuvelisa i-elektroniki.
