FR4 epoxy fiber board

A. Product introduction

FR-4 is also called FR4 epoxy board, and its classification is very wide. The main models are:
G11 : Flame retardant grade UL94V0 . In the dry and wet state, the electrical performance is still very good. It is a good choice for electrical insulation.
G10: The flame retardant grade UL94V2 , in the dry and wet state, the electrical performance is still very good, it is a good choice for electrical insulation parts
JC833: flame retardant grade UL94V0 , density within 1.8-2.0 , widely used in electrical and electronic insulation parts and Insulating plates for airplanes, motor cars, transformers, precision cruise ships , etc.
JC834: flame retardant grade UL94V0 , density within 1.8-2.0 , widely used in electrical and electronic insulation parts, aircraft, motor cars, transformer insulation boards, precision cruise ships , etc.
fr4 epoxy board introduces a plate-shaped insulating material made of glass fiber cloth impregnated with epoxy resin as an adhesive, dried and hot pressed. It has high mechanical properties, water absorption, flame retardancy and heat resistance, and stable dielectric properties after immersion in water. Suitable for products requiring high-performance electronic insulation, such as FPC reinforcement boards, PCB drilling pads, glass fiber mesons, carbon film printed glass fiber boards for potentiometers, and precision star gears ( wafer grinding ), Precision testing plates, electrical (electrical) equipment insulation stay partitions, insulation backing plates, transformer insulation plates, motor insulation parts, grinding gears, electronic switch insulation plates, etc.

D. Product characteristics

1. Variety of colors: Compared with 3240 yellow, FR-4 has white, yellow, aqua and black colors to choose from. And the surface is flat and smooth without bubbles, and the appearance is beautiful.
2 , fire rating: UL94V0 , fire zui grade. Different from the general fire rating, UL94V0 has achieved the effect of fire and flame retardant. It can self-extinguish in a short time after the material passes through the burning state, escorting the safety of life and property.
3. Strong insulation: FR-4 has a very strong natural insulation performance. In the dry and wet state, the electrical performance is still very good, and it is a good choice for electrical insulation.
4. High-quality and practical: FR-4 still has good adaptability in different environments . Whether it is minus 100℃ or high temperature 130℃ , it can be applied.
5. Wide range of applications: Because of the high quality of FR-4 and its strong plasticity, it is widely used in electrical and electronic insulation parts, as well as insulation boards for airplanes, motor cars, transformers, precision cruise ships, and so on.
