What Is The Difference Between Fiberglass Board And Epoxy Board And FR-4 Board
Generally, the epoxy board on the market is phenolic epoxy, and the yellow one is generally not used as the base material of hard circuit board, but for electrical purposes. FR4 is NEMA standard pure epoxy plate. The normal color should be dark green, which is the color of epoxy. There are also yellow ones. Generally speaking, yellow FR4 is called yellow material, and white (green) is called white material. FR-4 is more expensive than epoxy board, and the price of fiberglass board cannot be confirmed. Fiberglass board, also known as fiberglass board, is generally used to soft wrap the base course, and then wrap cloth art, leather, etc. outside to make beautiful wall and ceiling decoration. It is widely used. With sound absorption, sound insulation, heat insulation, environmental protection, flame retardant and other characteristics.
FR-4, also known as fiberglass board; Fiberglass board; FR4 reinforcing plate; FR-4 epoxy resin board; Flame retardant edge plate; Epoxy plate, FR4 smooth plate; Epoxy glass cloth plate; Circuit board drilling pad. Fiberglass board alias: fiberglass insulation board, fiberglass board (FR-4), fiberglass composite board, which is composed of fiberglass materials and high heat resistance composite materials, and does not contain asbestos harmful to human body. It has high mechanical and dielectric properties, good heat and moisture resistance, and good processability. For plastic mold, injection mold, machinery manufacturing, molding machine, drilling machine, injection molding machine, motor, pcb ICT fixture, table grinding pad.
