What's the difference between three kinds of glass fiber board, epoxy board and FR4 board?
Glass fiber board, also known as glass fiber board, commonly used in soft base cloth, leather bag, outside, a beautiful wall and ceiling decoration. Very wide range of applications. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection and flame retardance.FR-4 also known as the glass fiber; glass fiber board; FR4 reinforcing plate; FR-4 epoxy resin board; flame retardant insulation board; epoxy plate, FR4 plate; glass board; PCB drilling pad.
FR4 is the pure epoxy board of NEMA standard. The normal color should be dark green. This is the color of epoxy. There are also yellow, generally called yellow FR4 called yellow material, white (green) called white material.FR4 is more expensive than epoxy board and fiberglass board cannot confirm the price.
These three are glass fiber boards.Usually the epoxy board on the market is phenolic epoxy, yellow, which is generally not used as a hard circuit board substrate, is the use of electrical insulation.
The main raw material of PCB is E-glass cloth, fiber paper and epoxy resinGlass fiber sheet: base material, glass fiber clothEpoxy board: binder is epoxy resin
