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.
