Product Description

FR4 sheet is a kind of epoxy sheet (epoxy resin sheet), which is a composite material made of epoxy resin, an organic polymer compound, and glass fiber. The “fr” is the abbreviation for “flame retardant”, and fr4 sheet is a material that meets the “fr4” flame retardant rating.

There are many colors of fr4 sheet, such as white, black, green, blue and so on.

1、Characteristics of fr4 sheet

The surface of fr4 sheet is smooth and flat, and it is heat-resistant, moisture-resistant, mold-resistant, acid and alkali resistant, impact-resistant, and its mechanical properties, dielectric properties, and processing performance is good. Dry and wet state of the electrical properties are also excellent, the most important thing is that it has a very good flame retardant, by the environment has little influence, the size is very stable.

2、Application of fr4 sheet

The characteristics of fr4 sheet can be used for various circuit boards, electrical and electronic industry insulation structure, various switches, computer drilling pads, molds and fixtures, precision test plate production.

Different application areas for different colors of FR4 epoxy sheets

As we know, FR4 epoxy board has several different colors, zui common is natural color, yellow, black. The natural color is its natural color aqua green.

FR4 is a flame retardant material grade code, which represents the resin material after combustion state must be able to self-extinguish a material specification, that is, it has the characteristics of flame retardant. FR4 epoxy board is a certain level of flame retardant, but also has sufficient insulation properties of the insulating material, in many circuit boards have a wide range of applications.

This type of insulating material has stable electrical insulation properties, and the surface is smooth, flat, can be adapted to some high-performance electronic insulation products, which are more common transformer insulation board, motor insulation parts, electronic switch insulation board and so on.

Currently on the market FR4 epoxy board commonly used size 1020 * 1220, 1020 * 2440, 1020 * 2040

In this many colors of FR4 epoxy board, aqua green board is generally used in a wide range of computers, electronic switches, computer peripherals, communication products, office automation equipment, automation instrumentation, military and aviation electronics, household appliances and other products, because it has a good quality of stability and flatness, adapted to the requirements of surface mounting and packaging substrates.

The yellow color is widely used in digital display, dot matrix display, LED display, large screen display, electronic road signs, electronic signage substrate production, as well as special requirements of electronic and electrical insulation structure. Black substrate is widely used in optical instruments, cameras and other products, with stable quality, high flatness and other characteristics.

The black color is generally used in anti-static insulation projects or materials, with anti-static, flame retardant effect.
