FR4 Rigid Epoxy Glassfiber Rau Raina
Whakaahuatanga Hua
Ko tenei hua i whakakikoruatia e te teitei o te pāmahana me te pehanga teitei me te kakahu karaihe hiko kua whakapourihia ki te resin epoxy brominated.Me nga taonga miihini teitei, nga taonga dielectric me nga taonga aukati mura, me te pai o te wera me te makuku;
Ko te FR-4 he tohu mo te karaehe o nga rawa mura-a-te-ahi, ko te tikanga he tohu papanga ka taea e tetahi rawa kapia te tinei i muri i te wera.Ehara i te ingoa rawa, engari he tohu rauemi.Ko te ingoa FR4 i ahu mai i te punaha tohu NEMA kei reira te'FR'e tu ana mo'parenga ahi', kia rite ki te paerewa UL94V-0.Na reira, whānui PCB papa iahiko, He maha nga momo o FR-4 rauemi kōeke whakamahia, engari te nuinga o ratou he rauemi hiato hanga o Tera-Function epoxy resin ki filler me te muka karaihe.
Tautukunga ki nga Paerewa
