    Khoom Piav Qhia

    Cov khoom no tau laminated los ntawm qhov kub thiab kub siab nrog hluav taws xob glassfiber daim ntaub impregnated nrog brominated epoxy resin.Nws muaj cov tshuab muaj zog, lub zog dielectric thiab nplaim retardant khoom, nws kuj nrog zoo thaum tshav kub kub thiab noo noo tsis kam;

    FR-4 yog txoj cai ntawm qeb ntawm qib cov nplaim hluav taws cov ntaub ntawv, txhais tau tias cov khoom siv tshwj xeeb uas cov khoom siv ua khoom siv yuav tsum muaj peev xwm tua nws tus kheej tom qab hlawv. Nws tsis yog lub npe khoom siv, tab sis yog qeb khoom. Lub npe FR4 los ntawm NEMA muab qhab nia qhov twgFRsawv rau hluav taws kub retardant, ua raws li UL94V-0 tus qauvCov. Yog li no, cov qib hluav taws xob PCB Circuit Board, Muaj ntau hom FR-4 qib cov ntaub ntawv siv, tab sis feem ntau ntawm cov khoom siv yog ua los ntawm Tera-Muaj nuj nqi epoxy cob nrog muab tub lim thiab iav fiber.

    Kev Ua Raws Li Cov Qauv

    Raws li GB / T 1303.4-2009 hluav taws xob thermosetting cob muaj cov khoom lag luam tawv laminates - Tshooj 4: epoxy resin nyuaj laminates, IEC 60893-3-2-2011 insulating cov ntaub ntawv - hluav taws xob thermosetting resin muaj tawv laminates - Tshooj 3-2 ntawm cov khoom siv ntawm tus neeg specification EPGC202.
