What does FR-4 mean? FR-4 is a code for a grade of flame-resistant insulation materials, which means a material specification that resin materials must be able to extinguish by themselves after burning. It is not a material name, but a material grade. There are many types of FR-4 grade materials used in boards, but most of them are composite materials made of so-called Tera-Function epoxy resin with filler and glass fiber.
