What is the difference between FR4 material and general epoxy sheet?
FR4 epoxy sheet material is used for different purposes. Main technical features and applications: stable electrical insulation, good flatness, smooth surface, no pits, thickness tolerance standard. FR4 material is suitable for high performance electronic insulation products such as FPC reinforcement board, PCB drilling board and glass fiber muon, potentiator carbon film printed glass fiber board, precision gear, precision test plate, electrical equipment insulation support plate, insulation pads, transformer insulation board, motor insulation parts, abrasive, electronic switch insulation board, etc.
1. FR4 epoxy sheet color:
Yellow, white, black, blue, etc
FR4 epoxy sheet features: high mechanical properties, dielectric properties, heat resistance, moisture resistance, good machinability.
Application of FR4 epoxy sheet: used as insulation structural parts of motor and electrical equipment.
2. FR4 epoxy sheet application
The main material of FR4 epoxy sheet is imported semi-cured plate, and the color is white, yellow and green. It still has a higher mechanical strength under normal temperature 150℃. The electrical performance is good at dry and wet state. FR4 material is flame retardant, and is used as insulation structural parts of electrical, electronic and other industries. It uses imported raw materials, and domestic pressing machine by carefully manufacturing.
3. FR4 epoxy sheet
FR4 epoxy sheet is important substrates for manufacturing multilayer printed circuit board.
The mechanical properties, dimensional stability, impact resistance and moisture resistance of FR4 epoxy sheet are higher than those of paper base. It has excellent electrical performance, high working temperature, and the performance is less affected by the environment. In the processing technology, it has a great advantage over other resin-based glass fiberboard. This product is mainly used for double-sided printed circuit boards, and the consumption is big. In recent years, due to the development of electronic product installation technology and PCB technology, high FR-4 products appear.
