I-FR-4 iyikhodi yebanga lezinto ezimelana nelangabi, okusho ukucaciswa kwezinto okubalulekile okumele kukwazi ukuzicisha ngokwazo ngemva kokusha.Akulona igama elibonakalayo, kodwa ibanga lezinto ezibonakalayo.Ngakho-ke, amabhodi wesifunda we-PCB jikelele, Kunezinhlobo eziningi zezinto zebanga le-FR-4 ezisetshenzisiwe, kodwa eziningi zazo ziyizinto eziyinhlanganisela ezenziwe nge-Tera-Function epoxy resin ene-filler ne-glass fiber.

I-FR-4 epoxy glass cloth laminate, ngokusho kwabasebenzisi abahlukene, imboni ngokuvamile ibizwa ngokuthi: FR-4 Epoxy Glass insulation board, epoxy board, brominated epoxy board, FR-4, Glass fiberboard, FR-4 reinforced board, FPC reinforced board , ibhodi lesifunda eliguquguqukayo eliqinisiwe ibhodi, ibhodi le-epoxy le-FR-4, ibhodi lokufaka i-flame-retardant, i-FR-4 laminated board, i-FR-4 glass fiberboard, i-epoxy glass cloth board, i-epoxy glass cloth laminated board, ibhodi lesifunda lokubhola iphedi.

Igama elithi FR4 livela ohlelweni lokugreda lwe-NEMA lapho i-'FR' imele 'i-fire retardant', ehambisana nezinga le-UL94V-0.Inketho ye-FR4 ilandelwa yi-TG130.I-TG ibhekisela ekushiseni kwengilazi yenguquko - izinga lokushisa lapho izinto eziqiniswe ngengilazi zizoqala ukonakala futhi zithambe.Kumabhodi ajwayelekile e-Fusion leli nani lingu-130°C, elingaphezu kokwanele izinhlelo eziningi zokusebenza.Izinto ezikhethekile ze-High TG zingamelana namazinga okushisa angu-170 – 180°C, njengezinto zethu ezingu-3250.I-FR-5,G11 ingakwazi ukumelana namazinga okushisa angu-155°C.

Amalayini amaningi e-FR4 akweleta ukumelana kwawo nelangabi kokuqukethwe kwawo kwe-bromine, i-halogen engasasebenzi evame ukusetshenziswa ezimbonini ngenxa yezakhiwo zayo ezibambezela ilangabi.Lokhu kunikeza izinto ze-FR4 izinzuzo ezisobala njengempahla ye-PCB yesitoko ngokuphepha komlilo ngenkathi isensimini.Kuphinde kuqinisekise kancane uma amakhono akho e-soldering engekho ezingeni.

Kodwa-ke, i-bromine iyi-halogen okungamakhemikhali anobuthi obukhulu akhululwa endaweni lapho impahla ishiswa.Ngisho nenani elincane lanele ukulimaza abantu noma ngisho nokufa.Ukunciphisa ukusetshenziswa kwezinto ezinjalo eziyingozi emikhiqizweni yethu yansuku zonke, ama-laminates angenayo i-halogen FR4 atholakala kalula.

Muva nje sithuthukise amashidi amhlophe namnyama we-halogen-free FR4 epoxy glassfiber laminate, manje asetshenziswa njengebhodi eliqinisiwe le-FPC ku-iphone, amashidi okushisa, njalonjalo.
