 What is FR4 in PCB?

FR-4 is the code for the grade of refractory materials, which means that the resin material must be able to extinguish itself after burning. It is not the name of the material, but the grade of the material. Therefore, general PCB circuit boards have many types of FR-4 grade materials, but most of them are composite materials made of Tera-Function epoxy resin, filler and glass fiber.
