Fr4 Epoxy Glass Cloth Board is Improved Products that Has Strong Flame Resistance
- By : Insulation Materials
Descriptions of Fr4 Epoxy Glass Cloth Board:
FR4 is the base plate used by PCB, and it is a kind of sheet. According to the different reinforcing materials, the sheets are mainly classified into the following four types: FR4（ fiber glass cloth substrate）, FR1, FR2 and so on: paper substrate, CEM series: composite substrate, special material substrate (ceramics, metal base, etc.) FR4 laminated products are made of special electronic cloth impregnated with epoxy phenolic resin and other materials by hot pressing under high temperature and pressure.
Fr4 Epoxy Glass Cloth Board Features:
it has high mechanical and dielectric properties, good heat and moisture resistance and good machinability.
Applications of Fr4 Epoxy Glass Cloth Board:
As insulating structural parts in motor and electrical equipment, including various types of switch FPC to strengthen electrical insulation `carbon film printed circuit board `computer drilling pad `die fixtures'(PCB test stand) and can be used in humid environment and transformer oil.
The mechanical properties, dimensional stability, impact resistance and moisture resistance of FR4 epoxy board 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. Epoxy fiberglass cloth substrates, the most widely used product type is fr4. In recent years, due to the development of electronic product installation technology and PCB technology, high Tg FR4 products have emerged.
