What does an FR4 antistatic board consist of?

FR4 anti-static board is mainly composed of glass fiber and epoxy resin, processed by a specific process. The FR4 antistatic board consists of the following components:

‌Epoxy resin: Provides adhesion and mechanical strength of the material.

‌Carbon black: Filler to increase the electrical conductivity of the material and realize the anti-static function.

‌Fiberglass cloth: Reinforcing material that provides structural stability and mechanical strength.

Main features of the FR4 antistatic board

Excellent anti-static function: The FR4 antistatic board has a stable anti-static resistance value, usually within the range of 109Ω·cm, which can effectively prevent the accumulation of static electricity and damage to electronic equipment.

Stable dielectric properties: The material performs well in electrical properties, has stable insulation properties and dielectric constant, and is suitable for the manufacture and installation of various electronic devices.

Good processing performance: FR4 antistatic board is easy to process and cut, can be customized according to specific needs, easy to install and use in electronic equipment.

Excellent fire performance: The material has excellent fire performance, and the flame retardant grade is UL-94:V-0, which can prevent the spread of fire to a certain extent and ensure the safety of electronic equipment.

Uses of the FR4 antistatic board

Circuit board manufacturing and support:

FR4 antistatic boards are often used as substrate materials for circuit boards to provide stable support and electrical performance for circuits.

In a multilayer circuit board, the FR4 antistatic board acts as an interlayer insulation material to ensure electrical isolation between the layers of the circuit.

Electrostatic protection:

Due to its antistatic properties, the FR4 antistatic board can effectively prevent the damage of electrostatic discharge to electronic components and circuits.

During the manufacturing, testing, packaging, and transportation of electronic products, the FR4 antistatic board is used to make antistatic workbenches, antistatic packaging materials, and antistatic floors.

Electrical insulation:

The FR4 board has excellent electrical insulation properties and can be used as an insulating part of electrical equipment to prevent current leakage and short circuit.

Structural support and protection:

With high mechanical strength and stiffness, FR4 boards can be used to make enclosures, brackets and protective structures for electronic products to protect internal circuits and components from external shocks and vibrations.

Announcements

Note the following when using the FR4 antistatic board:

Avoid high temperature environment: Although the FR4 antistatic board has certain high temperature resistance, its performance may be affected by being in a high temperature environment for a long time.

Prevent mechanical damage: During use, avoid excessive mechanical damage to the FR4 antistatic board to avoid affecting its antistatic performance and service life.

Correct installation and use: Install and use the FR4 antistatic board according to relevant regulations and requirements to ensure the best antistatic performance.
