1. Different uses. The main raw materials for the production of circuit boards are alkali-free glass cloth, fiber paper, and epoxy resin. Fiberglass board: base material glass fiber cloth, epoxy board: binder is epoxy resin, FR4: base material cotton fiber paper. All three are fiberglass panels.
2. Different colors. Usually the epoxy board on the market is phenolic epoxy, yellow. It is not used as the base material of rigid circuit boards, and for electrical insulation purposes. FR4 is a NEMA standard pure epoxy sheet, and 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, flame retardant and so on. FR-4 is also known as glass fiber board; glass fiber 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 backing board.
Fiberglass board features:
The main technical characteristics and applications of white FR4 light board: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance exceeds the standard, suitable for products that require high-performance electronic insulation, such as FPC reinforcement board, tin furnace High temperature resistant plate, carbon diaphragm, precision planetary wheel, PCB test frame, electrical (electrical) equipment insulation partition, insulation backing plate, transformer insulation, motor insulation, deflection coil terminal board, electronic switch insulation board, etc.
Epoxy board is also called epoxy glass fiber board. It is made by bonding epoxy resin and going through heating and pressure processes. It has high mechanical properties in a medium-temperature environment, and electrical Stable performance, good moisture resistance and heat resistance, and contains active epoxy groups, which will form infusible and insoluble characteristics after cross-linking with various curing agents. It is characterized by strong adhesion and shrinkage powerful.
It is also the so-called fiberglass board, which is generally used for soft covering the base layer, and then covered with fabric, leather, etc. to make beautiful wall and ceiling decorations. The application is very extensive. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardant and so on.
