FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). After add copper layer on one or each side FR4, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal printed cricuit board (PCB). Printed circuit board using FR4 as core material will be named as FR4 PCB.
