FR4 Epoxy Fiberglass Laminated Sheet
Cov khoom qhia
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 cev rau 'fire retardant', ua raws li tus qauv UL94V-0.
Ua raws li cov qauv
TS EN ISO 60893-3-2-2011 Cov khoom siv hluav taws xob thermoset resin muaj zog laminates - Ntu 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating cov ntaub ntawv - hluav taws xob thermoset resin industrial hard laminates - Ntu 3-2 ntawm tus kheej cov khoom Specification ntawm EPGC202.
Daim ntawv thov
Cov khoom no feem ntau yog siv los ua cov khoom siv rau lub cev muaj zog thiab cov khoom siv hluav taws xob, suav nrog txhua yam kev hloov pauv, cov khoom siv hluav taws xob, FPC cov khoom siv zog, cov pa roj carbon zaj duab xis luam tawm Circuit Board, lub computer drilling pad, pwm thiab cov khoom siv smelting (PCB kuaj nplaim taws); thiab tseem haum nyob rau hauv ntub ib puag ncig thiab transformer roj.

FAQ
Q1: Koj puas yog tuam txhab lag luam lossis chaw tsim khoom?
Peb yog cov chaw tsim khoom ntawm hluav taws xob insulating composite, Peb tau koom nrog cov chaw tsim khoom thermoset rigid composite txij li xyoo 2003.Our peev yog 6000TONS / xyoo.
Q2: Qauv
Cov qauv yog dawb, koj tsuas yog yuav tsum tau them tus nqi thauj khoom.
Q3: Koj tuaj yeem lav qhov zoo ntawm cov khoom loj li cas?
Rau cov tsos, qhov loj thiab tuab: peb yuav ua tag nrho kev tshuaj xyuas ua ntej packing.
Rau kev ua tau zoo: Peb siv cov qauv ruaj khov, thiab yuav kuaj xyuas cov qauv tsis tu ncua, peb tuaj yeem muab cov ntaub ntawv tshuaj xyuas cov khoom ua ntej xa khoom.
Q4: Lub sijhawm khoom xa tuaj
Nws nyob ntawm kev txiav txim kom muaj nuj nqis. Feem ntau hais lus, lub sijhawm khoom xa tuaj yuav yog 15-20 hnub.
Q5: Pob
