FR4 Tiileng Epoxy Glassfiber Laminated Sheet
Tlhaloso ea Sehlahisoa
Sehlahisoa sena se ile sa laminated ka mocheso o phahameng le khatello e phahameng ka lesela la elektroniki la khalase le tšetsoeng ka resin ea epoxy e nang le brominated. Se na le thepa e phahameng ea mechini, thepa ea dielectric le thepa e thibelang malakabe, hape se na le khanyetso e ntle ea mocheso le khanyetso ea mongobo;
FR-4 ke khoutu ea sehlopha sa thepa e hanelang mollo, e bolelang tlhaloso ea thepa eo resin e lokelang ho khona ho e tima ka boeona ka mor'a ho cha. Hase lebitso la thepa, empa ke sehlopha sa thepa. Lebitso FR4 le tsoa tsamaisong ea ho beha lintlha ea NEMA moo'FR'e emela'sethibela-mollo', e lumellanang le maemo a UL94V-0Ka hona, liboto tsa potoloho tsa PCB tse akaretsang, Ho na le mefuta e mengata ea thepa ea sehlopha sa FR-4 e sebelisitsoeng, empa boholo ba tsona ke thepa e kopaneng e entsoeng ka resin ea epoxy ea Tera-Function e nang le filler le fiber ea khalase.
Ho Latela Melao
Ho ya ka GB/T 1303.4-2009 di-laminate tse thata tsa indasteri tsa resin ya thermosetting ya motlakase - Karolo ya 4: di-laminate tse thata tsa resin ya epoxy, IEC 60893-3-2-2011 thepa ya ho thibela mocheso - di-laminate tse thata tsa indasteri tsa resin ya thermosetting ya motlakase - Karolo ya 3-2 ya tlhaloso ya thepa ka nngwe EPGC202.
