FR-4 epoxy glass cloth laminate, ho ea ka basebelisi ba fapaneng, indasteri ka kakaretso e bitsoa: FR-4 Epoxy Glass insulation board, epoxy board, brominated epoxy board, FR-4, Glass fiberboard, FR-4 reinforced board, FPC e matlafalitsoeng ka boto. , tenyetseha potoloho boto matlafatsoa boto, FR-4 epoxy boto, lelakabe-retardant insulation boto, FR-4 laminated board, FR-4 khalase fiberboard, epoxy khalase lesela boto, epoxy khalase lesela laminated boto, potoloho boto cheka pad.

Lebitso FR4 le tsoa ho sistimi ea maemo ea NEMA moo 'FR' e emeng bakeng sa 'mollo retardant', e tsamaellanang le maemo a UL94V-0.Khetho ea FR4 e lateloa ke TG130.TG e bua ka mocheso oa khalase ea phetoho - mocheso oo thepa e matlafalitsoeng ka khalase e tla qala ho senyeha le ho nolofatsa.Bakeng sa liboto tse tloaelehileng tsa Fusion boleng bona ke 130°C, e leng ho fetang ho lekana lits'ebetso tse ngata.Lisebelisoa tse khethehileng tsa High TG li ka mamella mocheso oa 170 - 180 ° C, joalo ka lintho tsa rona 3250.
