Difference Between FR4 Insulation Board and FR5 Insulation Board
What is the difference between FR4 insulation board and FR5 insulation board, here is a introduction.
What is the difference between FR4 insulation board and FR5 insulation board? Here is the introduction.
FR-4 is a code of a grade of flame-resistant insulation materials, which means a material specification that a resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. There are many types of FR-4 grade materials used in the board, but most of them are composite materials made of so-called Tera-Function epoxy resin plus filler and glass fiber.
FR-4 epoxy glass cloth laminate, according to different uses, the industry is generally called: FR-4 Epoxy Glass Cloth, insulation board, epoxy board, epoxy board, brominated epoxy board, FR-4 , Glass fiber board, glass fiber board, FR-4 reinforcement board, FPC reinforcement board, flexible circuit board reinforcement board, FR-4 epoxy board, flame-retardant insulation board, FR-4 laminated board, epoxy board , FR-4 light board, FR-4 glass fiber board, epoxy glass cloth board, epoxy glass cloth laminate board, circuit board drilling pad.
Main technical characteristics and applications: electrical insulation, stable, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for products with high performance electronic insulation requirements, such as FPC reinforcement boards, PCB drilling pads , Glass fiber meson, potentiometer carbon film printed glass fiber board, precision planetary gear (wafer grinding), precision test plate, electrical (electrical) equipment insulation struts, insulation pads, transformer insulation boards, motor insulation parts, grinding Gears, electronic switch insulation plates, etc.
FR-5 has better advantages than FR-4:
1.Higher TG and TD;
2, better heat resistance, about twice that of ordinary FR-4;
3.Z-CTE is smaller, suitable for high multilayer boards;
4. T288 is better.
FR4,FR5 epoxy board is a plate-shaped laminate made of special electronic cloth impregnated with epoxy phenolic resin and other materials and hot-pressed at high temperature and pressure. It has high mechanical and dielectric properties, good insulation properties, heat resistance and moisture resistance, and has good machinability. Applications: Used as insulation structural parts in motors and electrical equipment, but also widely used For PCB testing; 幷 can be used in humid environmental conditions and transformer oil.
