What is the difference between FR4 epoxy fiberglass board and FR5 epoxy fiberglass board?

FR4 epoxy glass fiber board FR5 epoxy glass fiber board is a laminate product made of special electronic cloth impregnated with epoxy phenolic resin and hot pressed at high temperature and high pressure. It has high mechanical properties and dielectric properties, good insulation properties, heat resistance and moisture resistance, as well as good machinability. Application: used as insulating structural parts in motors and electrical equipment, and also widely used For PCB testing; and can be used in humid environment conditions and transformer oil.

FR4 epoxy glass fiber board has many names: FR-4 epoxy glass cloth laminate, according to different uses, the industry is generally called: FR-4 EpoxyGlassCloth, insulating board, epoxy glass fiber board, epoxy resin board, brominated Epoxy resin board, FR-4, fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad.

The main technical characteristics and applications of FR4 epoxy glass fiber board and FR5 epoxy glass fiber board: electrical insulation, stability, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for products with high-performance electronic insulation requirements. Such as FPC reinforcement board, 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 spacer, insulation pad Plates, transformer insulation plates, motor insulation parts, grinding gears, electronic switch insulation plates, etc.

Both have higher mechanical properties and dielectric properties, better insulation properties, heat resistance and moisture resistance, as well as good machining properties. Application: Used as insulation structural parts in motors and electrical equipment, and also widely used in PCB testing; and can be used in humid environment conditions and transformer oil.
