copper sheet

FR-4 epoxy board is a common electronic substrate material widely used in the manufacture of electronic products. It is a composite material composed of glass fiber cloth and epoxy resin.

FR-4 epoxy board has the following properties and uses:

High strength: FR-4 epoxy board has high mechanical strength and can withstand large pressure and impact.

Good heat resistance: FR-4 epoxy sheet is able to work for a long time in high temperature environment and has good heat resistance.

Strong corrosion resistance: FR-4 epoxy board has good corrosion resistance to many kinds of chemical substances, and can be used for a long time in harsh environments.

Good electrical insulation performance: due to the addition of glass fiber cloth, FR-4 epoxy board has excellent insulating properties, can effectively prevent current leakage.

Good processability: FR-4 epoxy board has good processability and can be easily cut, drilled and line designed.

FR-4 epoxy board is mainly used to manufacture printed circuit boards (PCB).PCB is an important part of electronic products, which carries electronic components and provides circuit connection function.FR-4 epoxy board, as a common substrate material, can be used to manufacture various types of electronic devices, such as cell phones, computers, televisions, automotive electronics and so on. It has a wide range of application prospects in the electronics industry.
