About
FR4 PCB laminate is a flame-retardant fiberglass composite material used as the substrate for printed circuit boards. This 1.6mm thick variant features 2oz copper cladding (70μm thick) on one or both sides. FR4 consists of woven fiberglass cloth impregnated with epoxy resin, manufactured through high-temperature pressing and curing processes. The material offers excellent electrical insulation, dimensional stability, and heat resistance up to 130°C. Makers and electronics manufacturers use FR4 for prototyping and production of PCBs in everything from Arduino projects to commercial electronics. Its standardized thickness and copper weight make it ideal for through-hole and surface-mount component assembly. The 2oz copper provides sufficient current-carrying capacity for most applications while maintaining good signal integrity. DIY electronics enthusiasts purchase FR4 sheets for custom PCB fabrication, while professional manufacturers buy in bulk for production runs.
