FR a cikin FR4 yana wakiltar mai ɗaukar wuta, kuma lamba 4 ta bambanta kayan daga sauran kayan a cikin wannan ajin. FR4 shine gilashin fiber mai ƙarfafa epoxy laminate wanda yayi kama da takardar zane na bakin ciki.Kalmar FR4 kuma tana wakiltar darajar da aka yi amfani da ita don yin waɗannan laminates.Tsarin fiberglass yana ba da kwanciyar hankali na tsari don kayan.Fiber gilashin an lulluɓe shi da epoxy mai hana wuta.Wannan yana ba da ƙarfin kayan abu da ƙaƙƙarfan kaddarorin inji.Duk waɗannan fasalulluka sun sa allon kewayawa na FR4 ya shahara sosai tsakanin masana'antun kwangilar lantarki.
Kwamitin da'ira na FR4 shima ya shahara saboda dalilai masu zuwa:
FR4 abu ne mai rahusa.
1, Yana da babban ƙarfin dielectric, wanda ke ba da gudummawa ga aikin rufin lantarki.
2, Kayan yana da babban ƙarfin ƙarfi-da-nauyi kuma yana da haske a cikin nauyi.
3, Yana da tabbacin danshi kuma yana da yanayin zafi.
4, Kayan yana da kyawawan kayan lalata wutar lantarki.
5, FR4 baya sha ruwa, don haka ya dace da kowane nau'in aikace-aikacen PCB na Marine.
6, kayan suna rawaya zuwa haske kore, manufa ga kowane aikace-aikace.Duk waɗannan fasalulluka sun sa ya dace da yanayi iri-iri.
Yaya aka tsara FR4 akan allunan da'ira bugu na FR4 na al'ada?FR4 yana aiki azaman tushen kowane PCB.Kayan yana lanƙwasa tare da foil na jan karfe.Yi amfani da zafi da m don laminate.Ana iya amfani da foil ɗin jan ƙarfe don laminate abu daga ɗaya ko bangarorin biyu.
