Difference between glass fiber board, epoxy board and FR4 board

What is the difference between glass fiber board, epoxy board and FR4 board？

1. Different uses. The main raw materials for the production of circuit boards are alkali-free glass cloth, fiber paper, and epoxy resin. Glass fiber board: base material glass fiber cloth, epoxy board: the binder is epoxy resin, FR4: base material cotton fiber paper. All three types are fiberglass boards.

2. Different colors. Usually the epoxy board on the market is phenolic epoxy, yellow. Not used as a hard circuit board substrate, electrical insulation purposes. FR4 is a pure epoxy sheet of NEMA standard. The normal color is dark green, which is the color of epoxy.

3. Different in nature. Fiberglass board has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, and flame retardant. FR-4 is also known as fiberglass board; fiberglass board; FR4 reinforcement board; FR-4 epoxy resin board; flame-retardant insulation board; epoxy board, FR4 light board. Epoxy glass cloth board; circuit board drilling pad. Features of fiberglass board:

Main technical characteristics and application of white FR4 light board: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance exceeding the standard, suitable for products with high-performance electronic insulation requirements, such as FPC reinforcement boards, through tin furnaces High temperature resistant plates, carbon diaphragms, precision cruisers, PCB test frames, electrical (electrical) equipment insulation partitions, insulation backing plates, transformer insulation parts, motor insulation parts, deflection coil terminal boards, electronic switch insulation boards, etc.

It is also the so-called fiberglass board, which is generally used for soft-clad base layer, and then covered with fabric, leather, etc., to make beautiful wall and ceiling decorations. The application is very wide. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, and flame retardant. The above is about the difference between fiberglass board, epoxy board and FR4 board.
