Difference between FR-4 and Printed circuit board

FR-4 vs. Printed circuit board

FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. A printed circuit board (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.
