Difference Between FR4 Insulating Board and FR5 Insulating Board

What’s the¬†difference between FR4 insulating board and FR5 insulating board? Here introduce you about it.

FR-4 is a code of fire-resistant insulation material grade, which means that the resin material must be able to extinguish itself after burning. It is not a material name, but a material grade. Therefore, there are many kinds of FR-4 grade materials used in general circuit boards, but most of them are so-called Tera function epoxy resin Plus fillers and fiberglass composites.
FR-4 epoxy glass cloth laminate is generally called FR-4 epoxy glass cloth, insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4, fiberglass board, fiberglass board, FR-4 reinforcement board, FPC reinforcement board, FPC reinforcement board, FPC reinforcement board, FR-4 epoxy resin board, flame retardant insulation board, FR-4 laminate, epoxy board, FR-4 light board FR-4 glass fiber board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad.
Main technical features and application: electrical insulation, stability, flatness, smooth surface, no pit, thickness tolerance standard, suitable for products with high-performance electronic insulation requirements, such as FPC reinforcing plate, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision star gear (wafer grinding), precision test plate, electrical (Electrical) equipment insulation support Strip partition board, insulation pad, transformer insulation board, motor insulation parts, grinding gear, electronic switch insulation board, etc.

Compared with FR-4, FR-5 has better advantages:
1. TG and TD are higher;
2. The heat resistance is better, about twice that of FR-4;
3. Z-cte is smaller and suitable for high multilayer board;
4. T288 is better.
Fr4fr5 epoxy board is a board like laminated product made of special electronic cloth soaked with epoxy phenolic resin and other materials by high temperature and high pressure hot pressing. It has high mechanical and dielectric properties, good insulation, heat resistance and moisture resistance, and good machinability. Application: used in electrical machinery and electrical equipment as insulation structural parts, also widely used in PCB testing, and can be used in humid environment and transformer oil.
