Product Description

What is FR-4?


FR-4 is a code for the grade of fire-resistant materials, which means that the resin material must be able to extinguish itself after burning.

It is not a material name, but a material grade, so there are many kinds of FR-4 grade materials used in general circuit boards at present, but most of them are made of so-called Tera-Function epoxy resin with Filler and glass fiber.

FR-4 epoxy glass cloth laminate, according to the use of different, the industry is generally known as: FR-4 Epoxy Glass Cloth, insulating board, epoxy board, brominated epoxy board, FR-4, glass fiberboard, FR-4 reinforced board, FPC reinforced board, flexible circuit board reinforced board, FR-4 epoxy board, flame retardant insulation board, FR-4 laminated board, FR-4 glass fibre board, epoxy glass cloth board, epoxy glass cloth laminate, PCB drilling pad.

Main technical features and applications: stable electrical insulation performance, good smoothness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation requirements of products.

The surface color of FR-4 epoxy glass cloth laminate is as follows:

Yellow FR-4, white FR-4, black FR-4, blue FR-4, etc.

FR-4 is the base plate used by PCB, and it is a kind of sheet metal. According to the different reinforcing materials, sheets are mainly classified into the following four types:


1) FR-4: Glass Cloth Substrate
2) FR-1, FR-2, etc.: Paper Substrate
3) CEM Series: Composite Substrate
4) FR-4 of special material substrates (ceramics, metal substrates, etc.) is a plate-like laminated product made of epoxy phenolic resin and other materials impregnated with special electronic cloth by hot pressing at high temperature and pressure.

(5) Thermoplastic materials

Characteristic


FR-4 Epoxy Glass Fiber Cloth Substrate is a kind of Substrate with epoxy resin as binder and electronic glass fiber cloth as reinforcing material. Its bonding sheet and thin copper clad laminate with inner core are important substrates for making multi-layer Printed Circuit Boards.

Performance and Application


The mechanical properties, dimensional stability, impact resistance and moisture resistance of epoxy glass fiber cloth substrate are higher than those of paper substrate. Its electrical performance is excellent, its working temperature is high, and its performance is less affected by the environment. Compared with other resins, the glass fiber cloth substrate has great advantages in processing technology. This kind of product is mainly used for double-sided PCB, which has a large amount of usage. FR4 is also widely used as LED PCB in LED and other industries.
