FR4 Rigid Epoxy Glassfiber Laminated Sheet
Kev piav qhia txog khoom
Cov khoom no tau laminated los ntawm qhov kub thiab txias siab nrog cov ntaub iav hluav taws xob impregnated nrog brominated epoxy resin. Nws muaj cov khoom siv kho tshuab siab, cov khoom dielectric thiab cov khoom nplaim taws retardant, nws kuj nrog kev tiv thaiv cua sov zoo thiab noo noo tsis kam;
FR-4 yog ib daim code ntawm ib qib ntawm cov khoom siv uas tiv taus hluav taws, uas txhais tau tias yog cov khoom siv uas cov khoom siv resin yuav tsum muaj peev xwm tua hluav taws tom qab hlawv. Nws tsis yog lub npe khoom siv, tab sis yog qib khoom siv. Lub npe FR4 los ntawm NEMA grading system qhov twg'FR'sawv cev rau'tiv taus hluav taws'ua raws li tus qauv UL94V-0Yog li ntawd, cov laug cam PCB dav dav, Muaj ntau hom khoom siv FR-4 qib siv, tab sis feem ntau ntawm lawv yog cov khoom sib xyaw ua los ntawm Tera-Function epoxy resin nrog cov khoom sau thiab iav fiber.
Kev Ua Raws Li Cov Qauv
Raws li GB/T 1303.4-2009 hluav taws xob thermosetting resin industrial hard laminates - Ntu 4: epoxy resin hard laminates, IEC 60893-3-2-2011 cov ntaub ntawv rwb thaiv tsev - hluav taws xob thermosetting resin industrial hard laminates - Ntu 3-2 ntawm cov khoom siv ib leeg EPGC202.
