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 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.

FR-4 epoxy ie tioata laminate, e tusa ai ma tagata eseese, o le alamanuia e masani ona taʻua: FR-4 Epoxy Glass laupapa insulation, laupapa epoxy, laupapa epoxy brominated, FR-4, laupapa fiberboard, FR-4 laupapa faʻamalosia, FPC laupapa faʻamalosia. , laupapa fe'avea'i fe'avea'i fa'amalosia laupapa, FR-4 epoxy laupapa, afi fa'alumaina laupapa, FR-4 laminated laupapa, FR-4 tioata fiberboard, epoxy laupapa ie tioata, epoxy ie tioata laminated laupapa, laupapa matagaluega vili laupapa.

O le igoa FR4 e sau mai le NEMA fa'avasegaina o lo'o fa'atusa ai le 'FR' mo le 'fa'asa'o afi', e tusa ai ma le fa'atonuga UL94V-0.Ole filifiliga FR4 e soso'o ma le TG130.O le TG o loʻo faʻatatau i le suiga o le vevela tioata - o le vevela lea e amata ai ona faʻaleagaina ma faʻamalulu le mea faʻamalosi tioata.Mo laupapa masani a Fusion o lenei tau o le 130 ° C, lea e sili atu nai lo le tele o talosaga.O mea faʻapitoa High TG e mafai ona tatalia le vevela o le 170 - 180 ° C, e pei oa tatou mea 3250. O le FR-5, G11 e mafai ona faʻafeiloaʻi le vevela o le 155 ° C.

Ole tele ole FR4 laminates e fa'ato'a le mu ile mea ole bromine, ole halogen e le mafai ona fa'aogaina e masani ona fa'aogaina ile alamanuia mo ana mea e fa'agata ai le mu.O lenei mea e maua ai le FR4 mea faʻapitoa faʻapitoa e avea o se mea faʻasoa PCB i tulaga o le saogalemu afi aʻo i totonu o le fanua.E fai lava si fa'amafanafanaga pe afai e le'o fa'atumauina lou tomai fa'a sosolo.

Ae ui i lea, o le bromine o se halogen o ni vailaʻau sili ona oona e faʻasaʻoloto i le siosiomaga pe a faʻamumu le mea.E oo lava i nai vaega itiiti ua lava lea e faapogaia ai se afaina matuia i tagata po o le oti foi.Ina ia fa'aitiitia le fa'aogaina o ia mea mata'utia i totonu oa tatou oloa i aso uma, o lo'o avanoa FR4 laminates e leai se halogen.

Talu ai nei na matou atiaeina ai le paʻepaʻe ma le uliuli halogen-free FR4 epoxy glassfiber laminate pepa, o lea ua faʻaaogaina e pei o le FPC faʻamalosia laupapa i le iphone, faʻamafanafana pepa, ma isi.
