FR4 Rigid Epoxy Glassfiber Laminated Pepa
Fa'amatalaga o oloa
O lenei oloa na faʻapipiʻiina e le maualuga o le vevela ma le maualuga o le mamafa ma le ie tioata tioata faʻaeletoroni ua faʻapipiʻiina i le epoxy resin.It ma le maualuga o mea faʻainisinia, mea dielectric ma mea e faʻafefe ai le afi, e iai foʻi ma le vevela lelei ma le susu;
FR-4 o se fa'ailoga o se vasega o mea e tete'e mu, o lona uiga o se fa'amatalaga mea e tatau ona tineia e se mea resini pe a uma ona mu.E le o se igoa faaletino, ae o se tulaga faaletino.O le igoa FR4 e sau mai le NEMA faiga fa'ailoga lea e'FR'e tu mo'fa'asao afi', e tusa ai ma le tulaga UL94V-0.O le mea lea, lautele PCB laupapa matagaluega, E tele ituaiga o mea FR-4 vasega o loʻo faʻaaogaina, ae o le tele oi latou o mea tuʻufaʻatasia e faia i le Tera-Function epoxy resin ma filler ma tioata fiber.
Tausia ma Tulaga Fa'atonu
E tusa ai ma le GB/T 1303.4-2009 eletise faʻamaʻi eletise laminate faʻaulufalega - Vaega 4: epoxy resin laminates malo, IEC 60893-3-2-2011 mea faʻapipiʻi - eletise eletise eletise faʻaluma fale gaosi oloa - Vaega 3-2 o mea taʻitasi. faʻamatalaga EPGC202.
Vaega
1. High mea tau masini;
2. High dielectric meatotino;
3.Mechinability lelei
4.Good susu tetee;
5.Good tetee vevela;
6. Temperature tetee: Vasega B
7.Flame retardant meatotino:UL94 V-0
Fa'aaogāga
O lenei oloa e masani ona faʻaaogaina e avea ma vaega faʻavae mo afi ma mea eletise, e aofia ai ituaiga uma o ki、meafaigaluega eletise、FPC faʻamalosia ipu、laupapa ta'avale lolomi ata tifaga carbon、pusa vili komepiuta、limu ma smelting meafaigaluega (su'ega afi afi PCB）ma talafeagai foi i lalo ole siosiomaga susu masuau'u transformer.
