FR4 is a kind of material. People who pay attention to Tainuo insulating material should know about it. It is often called FR4 plate. It is also said that FR4 insulating plate is a kind of plate with good quality and good flame retardancy. FR4 is our name for the fire resistance grade of plate. The color and properties of FR4 plate are different because of the different materials in production It's different. Tainuo insulation material brings you to know what materials FR4 plate is made of and what advantages it has.

       Fr4fr5 epoxy laminate is made of special electronic cloth impregnated with epoxy phenolic resin and other materials by high temperature and high pressure hot pressing. It has high mechanical and dielectric properties, good insulation performance, heat resistance and moisture resistance, and good machinability. It is mainly used in motor and electrical equipment as insulation structure parts, and also widely used in PCB testing. It can be used in humid environment and transformer oil.

       Main technical features and applications of FR4 plate: electrical insulation, stability, good flatness, smooth surface, no pits, thickness tolerance standard, suitable for high-performance electronic insulation products, such as FPC reinforcing plate, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision planetary gear (wafer grinding), precision test plate, electrical (Electrical) equipment Insulation spacer, insulation pad, transformer insulation board, motor insulation parts, grinding gear, electronic switch insulation board, etc.

       These are the insulation materials of Qingdao Tino. The deep interpretation of FR4 sheet is the upper material and FR4 represents copper clad plate. In a straight way, FR4 is a very good flame resistant plate, which is generally used in the electronic and electrical industry, because it has very good performance presentation. Therefore, the plate quality here is high in the process of FR4 plate Our products are sold overseas and recognized by customers. We are looking forward to your consultation here.
