FR-4 classification:
The surface colors of FR-4 epoxy glass cloth laminate are include:
Yellow FR-4, white FR-4, black FR-4, blue FR-4, etc.
FR-4 is a type of sheet and used for PCB as the substrate. According to the different of reinforcement materials, the FR4 sheets are mainly classified into the following four types:
FR-4 is a laminate board that obtained by immersing epoxy resin with alkali-free glass fiber cloth by pressing under high-temperature and high-pressure,it’s rigid insulating laminated sheet.
Features: High mechanical and dielectric properties, good heat and moisture resistance and good machinability.
Uses: Insulation structural parts in motors and electrical equipment, including various types of switches FPC reinforced, electrical insulating carbon film printed circuit boards, computer drilling mat mold fixtures (PCB test racks) and in humid environmental conditions and Used in transformer oil.
FR-4 is a code name of a flame-resistant material grade. It means a material specification that the resin material must be self-extinguishing after being burned. It is not a material name, but a material grade, so the current general circuit is used by many types of FR-4 grades,but most of them are made of Tera-Function epoxy with filler and glass fiber.
FR-4 Epoxy Glass Cloth Laminate,according to the industry applications,also known as FR-4 Epoxy Glass Cloth,Insulation Board,Epoxy resin Board, Brominated Epoxy Board, FR-4 , fiberglass board, FR-4 reinforcing board, FPC reinforcing board, flexible circuit reinforcing board, FR-4 epoxy board, flame retardant insulation board, FR-4 laminated board, epoxy board , FR-4 light board, FR-4 glass fiber board, epoxy glass cloth board, circuit board drilling pad.
Electrical insulation Stable, good flatness,smooth surface,standard thickness tolerance.
Suitable for high-performance electronic i
