Selecting Solder Pallet Materials for SMT: Durostone, Ricocel, and TFEUR
Learn how to choose the best solder pallet materials for SMT production, comparing the properties and benefits of Durostone, Ricocel, and TFEUR.
Solder pallets (also known as reflow fixtures) play an essential role in SMT (Surface Mount Technology) production. They support PCB boards as they pass through the reflow soldering furnace and protect specific areas of the PCB from the harmful effects of high temperatures. The choice of material for solder pallets is critical as it must have key properties such as high-temperature resistance, wear resistance, and anti-static capabilities.
Common Solder Pallet Materials
There are several popular materials used in solder pallets today. Below we explore the characteristics of the most commonly used materials: Durostone, Ricocel, and Tfuer.
Durostone: High-Temperature Resistance and Durability
Durostone is a widely used thermoset material that excels in thermal stability, chemical corrosion resistance, and mechanical strength. It is particularly suited for high-temperature environments during soldering but may not offer the same thermal conductivity as some other materials. Durostone is a glass-fiber-reinforced plastic known for its outstanding high-temperature resistance (up to 350°C), high mechanical strength, and resistance to deformation.
- Advantages: High-temperature resistance, wear resistance, long lifespan.
- Disadvantages: High cost, difficult to process.
- Popular Models: Durostone UTR, Durostone CHP7.
Ricocel: Lightweight and Environmentally Friendly
Ricocel is a lightweight material that is highly resistant to thermal shock. It is more environmentally friendly than Durostone and performs well in high-frequency soldering applications due to its good thermal conductivity. Ricocel is a high-density synthetic material with excellent high-temperature resistance (up to 300°C) and a lighter weight compared to alternatives.
- Advantages: High-temperature resistance, lightweight, easy to process.
- Disadvantages: Relatively lower mechanical strength, vulnerable to impact damage.
Tfuer T301 and T315: Comparing Two High-Performance Solder Pallet Materials
Tfuer T301 and T315 are both excellent solder pallet materials with high-temperature resistance, but they differ in a few key areas:
| Material Model | High-Temperature Resistance | Mechanical Strength | Density | Recommended Use |
|---|---|---|---|---|
| Tfuer T301 | 300°C | Medium | 1.8g/cm³ | Suitable for medium temperature and strength requirements |
| Tfuer T315 | 350°C | High | 2.0g/cm³ | Suitable for high-temperature and high-strength applications |
- Tfuer T301: Ideal for applications requiring high-temperature resistance and low thermal expansion. It remains structurally stable under prolonged high-temperature use and is suitable for more demanding environments.
- Tfuer T315: T315 offers superior corrosion resistance and mechanical strength compared to T301. It is ideal for applications that require high corrosion resistance and greater mechanical durability. T315 also excels in surface stability and wear resistance.
Selecting the Right Material for Your Soldering Needs
- If the soldering process involves high thermal shock or elevated temperatures, Tfuer T301 or T315 is recommended for their enhanced thermal stability and resistance to deformation.
- For applications requiring excellent corrosion resistance and greater mechanical strength, Tfuer T315 is the best choice.
- If the environment is milder or lightweight is a priority, Ricocel is a suitable option as it performs excellently in these conditions.
Price Comparison: Durostone, Ricocel, Tfuer T301, and T315
In general, Tfuer T301 is a more economical option, while T315 is slightly more expensive. However, due to its lightweight and excellent environmental performance, it is ideal for specific high-frequency applications. Durostone and Ricocel are typically more expensive because they offer superior technical performance and durability, making them well-suited for harsh working environments.
Conclusion: Choosing the Right Solder Pallet Material for Your Application
The best solder pallet material depends on your specific soldering application. By understanding the properties and advantages of materials like Durostone, Ricocel, and Tfuer T301/T315, you can make a more informed decision. Consider factors like temperature resistance, mechanical strength, environmental impact, and cost to select the ideal material for your needs.
