Learn PCB and Buy PCB --- Laminates --- FR-4 brief
FR-4 (or FR4) is a kind of material grade designation, which means that the resin material is flame
resistant (self-extinguishing). FR-4 is a kind of material specifications, not a material name, but a
material grade. "FR" stands for flame retardant, and denotes that safety of flammability of FR-4 is
in compliance with the standard UL94V-0.
FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate with good
strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an
electrical insulator possessing considerable mechanical strength. The material is also known to
retain its high mechanical values and electrical insulating qualities in both dry and humid
conditions. These attributes, along with good fabrication characteristics, lend utility to this grade
for a wide variety of electrical and mechanical applications.
