FR-4 epoxy board is suitable for high performance electrical insulation.

FR4 is not an insulating material name

FR-4 is a kind of combustible material grade, which means that the resin material must be extinguished by its combustion state. It is not a material name, but a material grade. So the FR-4 grade material used in the general circuit board is very many, but most of them are used. The so-called four functional epoxy resin plus filler and glass fiber made of composite materials.

FR-4 main technical features and applications

Electrical insulation performance is stable, smooth, smooth surface, no dent, thickness tolerance standard, suitable for high performance electronic insulation requirements, such as FPC reinforcement plate, PCB drilling pad, glass fiber meson, potentiometer carbon film printing glass fiberboard, precision travel star gear (crystal grind), precision test plate, electrical (Electrical) equipment insulation supporting plate, insulation pad, transformer insulation plate, motor insulation, grinding gear, electronic switch insulation board, etc.

The main material of FR4 epoxy fiberglass board

the main material is imported semi solidified sheet, which has white, yellow and green color. It still has high mechanical strength at 150 C. It has good electrical properties under dry and wet state. It is used for insulation parts of electrical and electronic industries. Imported raw materials, domestic press and standard are used. The process is carefully made.
