1. The choice of PCB material is dependent on the specific requirements and environmental considerations of the product.
2. Various materials possess distinct characteristics and are suitable for different electronic products.
3. Selecting the right PCB material is essential for ensuring optimal performance and reliability of the product.
Commonly used materials for manufacturing PCBs
1. FR-4
This is one of the most commonly used materials in PCBs. It is a glass-reinforced epoxy laminate. The epoxy resin used is flame retardant and waterproof, providing a good strength-to-weight ratio and high tensile strength.
2. PTFE
Polytetrafluoroethylene is a plastic material that does not provide any resistance and is therefore used for high-speed and high-frequency applications. PTFE is very flexible and valuable in applications with strict tolerances. It is also lightweight, flame retardant, and has high physical strength, temperature stability, and versatility in various industries.
3. Metals
Traditional materials such as copper, aluminum, and iron are still used in PCBs. They allow the use of surface mount technology to integrate components and provide mechanical durability, resulting in a longer product life for metal-based PCBs.
4. Resin
Epoxy resin is a commonly used material in the PCB industry. Thermally cured materials can produce polymer polymerization reactions, providing excellent electrical insulation and serving as an adhesive with characteristics such as electrical resistance, heat resistance, chemical resistance, and water resistance.
5. Aluminum substrate
The main component of the aluminum substrate is aluminum, composed of copper skin, an insulation layer, and an aluminum sheet. It has excellent heat dissipation function and is widely used in the LED lighting industry.
Common PCB material brands
1. Rogers material
Rogers high-frequency PCB material is a modern and high-performance composite material made of glass fiber as the reinforcing material and aromatic polyimide resin as the basic material through multi-layer composite processing. It offers excellent dielectric properties, high electromagnetic performance, high mechanical strength, and reliability. It is widely used in communication, medical, military, satellite communication, aerospace, automotive electronics, and other fields.
2. Shengyi Technology
Shengyi Technology produces high-performance PCB board materials, including FR4, high TG FR4, and aluminum substrates, widely used in telecommunications, computers, consumer electronics, automotive electronics, and LED lighting.
3. FR4
FR4 is a strong PCB material enterprise, mainly producing high-performance functional materials for different application scenarios, including high-frequency circuit boards, microwave circuit boards, and RF circuit boards.
When selecting PCB material, it is essential to consider the electrical characteristics, thermal conductivity, mechanical strength, and other requirements of the board based on different application scenarios.
