ED Copper Foils mo FPC
Folasaga o oloa
Electrolytic copper foil mo FPC ua fa'apitoa ona atia'e ma gaosia mo le FPC alamanuia (FCCL).O lenei pepa apamemea electrolytic e sili atu le ductility, maualalo roughness ma sili atu le malosi pa'u nai lo isi pepa apamemea.I le taimi lava e tasi, e sili atu le faʻamaeʻaina o le pito i luga ma le faʻalelei o le pepa apamemea ma o le gaugau o le teteʻe e sili atu foi nai lo mea faapena.Talu ai o lenei pepa apamemea e faʻavae i luga o le electrolytic process, e le o iai le gaʻo, lea e faigofie ai ona tuʻufaʻatasia ma mea TPI i le maualuga o le vevela.
Fuafuaga
Mafiafia: 9µm～35µm
Fa'atinoga
O le pito i luga o le oloa e uliuli pe mumu, e maualalo le roughness luga.
Talosaga
Lamina Fa'aofuofu Fa'a'ofu Fe'ai (FCCL), Fine Circuit FPC, fa'apupulaina tioata manifinifi ata tifaga.
Vaega
High density, maualuga le punou tetee ma lelei etching faatinoga.

Fa'aaliga:1. Copper foil oxidation resistance performance and surface density index e mafai ona feutagai.
2. O le faʻasologa o faʻatinoga e faʻatatau i la tatou metotia suʻega.
3. O le taimi faʻamaonia lelei o le 90 aso mai le aso na maua ai.
