FR4 Rigid Epoxy Glassfiber Laminated Sheet
Bayanin samfur
Wannan samfurin da aka laminated da high zafin jiki da kuma high matsa lamba tare da lantarki glassfiber zane impregnated da brominated epoxy resin.It tare da high inji Properties, dielectric Properties da harshen retardant Properties, shi ma tare da mai kyau zafi juriya da danshi juriya;
FR-4 lambar daraja ce ta kayan da ba ta da harshen wuta, wanda ke nufin ƙayyadaddun kayan da kayan guduro dole ne su iya kashe su da kansu bayan sun ƙone.Ba sunan abu bane, amma darajar kayan abu.Sunan FR4 ya fito ne daga tsarin NEMA grading inda'FR'yana tsaye don'mai kare wuta', mai yarda da ma'aunin UL94V-0.Don haka, allunan da'ira na PCB na gaba ɗaya, Akwai nau'ikan kayan aikin FR-4 da yawa da ake amfani da su, amma galibin su kayan haɗin gwiwa ne na Tera-Function epoxy resin tare da filler da fiber gilashi.
