ED Copper Foils rau FPC
Khoom Taw Qhia
Electrolytic tooj liab ntawv ci rau FPC yog tsim tshwj xeeb thiab tsim rau FPC kev lag luam (FCCL).Cov ntawv ci tooj liab electrolytic no tau zoo dua ductility, qis roughness thiab zoo dua tev lub zog dua li lwm cov ntawv tooj liab.Nyob rau tib lub sijhawm, qhov ua tiav thiab qhov zoo ntawm cov ntawv ci tooj liab zoo dua thiab cov folding kuj tseem zoo dua li cov khoom siv tooj liab zoo sib xws.Txij li cov ntawv ci tooj liab no yog ua raws li cov txheej txheem electrolytic, nws tsis muaj roj, uas ua rau nws yooj yim rau kev sib xyaw nrog TPI cov ntaub ntawv ntawm qhov kub thiab txias.
Dimension Range
Thickness: 9μm ~ 35μm
Kev ua yeeb yam
Cov khoom nto yog xim dub lossis xim liab, muaj qhov roughness qis dua.
Daim ntawv thov
Flexible Copper Clad Laminate (FCCL), Fine Circuit Court FPC, LED coated siv lead ua nyias zaj duab xis.
Nta
High ceev, siab dabtsi yog khoov kuj thiab zoo etching kev ua tau zoo.
Microstructure
SEM (Ua ntej kho deg)
SEM (Sab ci ntsa iab tom qab kho)
SEM (Rough Sab Tom Qab Kho)
