FR4 Rigid Epoxy Glassfiber Laminated Sheet
Product Description
Cov khoom no tau laminated los ntawm qhov kub thiab txias siab nrog hluav taws xob iav fiber ntau daim ntaub impregnated nrog brominated epoxy resin.It nrog cov neeg kho tshuab siab, dielectric zog thiab nplaim retardant zog, nws kuj muaj zoo kub tsis kam thiab noo noo tsis kam;
FR-4 yog ib qho kev cai ntawm qib ntawm cov khoom siv hluav taws xob, uas txhais tau hais tias cov khoom siv tshwj xeeb uas cov khoom siv cob yuav tsum muaj peev xwm tua tau los ntawm nws tus kheej tom qab hlawv.Nws tsis yog lub npe khoom, tab sis qib khoom siv.Lub npe FR4 los ntawm NEMA grading system qhov twg'FR'sawv rau'hluav taws kub retardant', ua raws li tus qauv UL94V-0.Yog li ntawd, feem ntau cov PCB Circuit Court boards, Muaj ntau ntau hom FR-4 cov ntaub ntawv siv, tab sis lawv feem ntau yog cov ntaub ntawv sib xyaw ua los ntawm Tera-Function epoxy resin nrog muab tub lim thiab iav fiber ntau.
Ua Raws Li Cov Qauv
