I-FR4 ayilona igama lezinto ezibonakalayo, kepha uhlobo lwebanga lokumelana nomlilo, elifanekisela izinto zokugcina lingazifihla lapho lidubula. Manje zikhona zonke izinhlobo zezinto ezisetshenziswayo ze-FR4 ezisebenzisa njenge-PCB, kepha iningi liyinhlanganisela eyenziwe nge-epoxy resin, i-filler kanye ne-fiberglass.

I-G10 Fr4 Ishidi elisetshenziswa kakhulu njengezingxenye zokwakheka kwezindawo zokufakwa ngogesi , nge-elekthronikhi nakwezinye izimboni .
Izici ezibalulekile:
• Ukumelana nelangabi
• Amandla aphezulu we-dielectric
• Ukumelana nomswakama
• Ukuvimbela Ukumelana
• Ukumelana Nezinga: 180-200 ℃
• Ngaphansi kokushisa okujwayelekile kwe-150 ℃, kusenamandla amakhulu emishini.
