High-Quality Teflon PCBs with Competitive Pricing
What is Teflon PCB?
Teflon PCBs are circuit boards made of Teflon material offering superior performance and reliability. Teflon printed circuit is also called PTFE PCB. Teflon is a unique material with exceptional electrical, mechanical, and chemical properties. Printed circuit boards produced by Telflon material can be used in various applications such as power supplies, automotive electronics, medical equipment, and robotics systems. They are also highly resistant to extreme temperatures and other harsh environmental conditions, making them ideal for use in many industrial settings.
Our engineers say, “Teflon PCBs provide excellent thermal conductivity, which helps reduce heat buildup during operation while providing greater efficiency than traditional FR-4-based circuit boards.” Teflon also offers superior protection against moisture intrusion compared to standard epoxy glass laminates providing increased safety in hazardous environments.
In Viasion, we produce high-quality Teflon printed circuits which offer higher performance levels with improved durability over conventional materials and ensure that they are the preferred choice for many applications where high-quality components are needed for reliable operation.

The Advantages of Teflon PCB
Precautions for Viasion in Manufacturing Teflon PCB
Teflon PCBs would not have become so popular in various electronic applications without their superior performance characteristics, including low dielectric constant and excellent temperature resistance. However, Teflon PCBs present some unique challenges when it comes to manufacturing. To ensure the best performance and reliability of PCBs made with Teflon material, Viasion adheres to the following best practices.
First, Teflon is a much harder material than FR-4, requiring more aggressive drilling parameters to achieve good hole quality. Second, Teflon drills should be kept sharp and often rotated to avoid burning the Teflon; Teflon can quickly melt under too much heat.
Additionally, Teflon is known to be prone to delamination, so Viaison manufactures printed circuit boards on high-accuracy laser machines.
Teflon has a very low coefficient of thermal expansion, meaning that regular Teflon boards can suffer from warped edges and misalignment when exposed to drastic temperature changes. To prevent this issue, Viaison uses flexible Teflon substrates.
Finally, Teflon is a high-resistivity material that can be difficult to solder. Thus, Viaison only handles this kind of PCB with lead-free processes and takes special care when soldering due to the low melting temperature of Teflon.
By following these best practices, Teflon PCBs made in Viaison can provide reliable operation and superior performance in demanding applications.
The Basics of Teflon PCB Design
- The design of a PCB with Teflon material is relatively straightforward. However, there are some important considerations to keep in mind when designing a Teflon printed circuit board.
- The first step in designing a Teflon printed circuit board is to create a schematic outlining the board’s components and connections.
- The next step is to select Teflon as the material for the circuit board. Teflon comes in various thicknesses and grades, so choosing the grade that best suits your application is essential.
- Teflon printed circuit boards should also be designed with adequate thermal management features, such as heat sinks or cooling fins.
- Finally, the fabrication of Teflon printed circuit boards requires special tools and techniques. Teflon-specific drill bits and routers must be used to ensure that the Teflon is not damaged during manufacturing.
- If Teflon PCBs are poorly designed, they can’t function well in various applications.
Trends in Telfon PCB Technology
Teflon printed circuit boards are quickly becoming one of the most popular choices for PCBs in terms of their superior insulation and durability. Teflon is a fluoropolymer with excellent dielectric strength and low thermal conductivity – making it an ideal material for printed circuit boards. Additionally, Teflon has excellent high-temperature performance, chemical resistance, and a wide range of resistivities and dielectric constants.
Teflon PCBs are typically used in applications that require exceptionally precise operation – such as telecommunications, aerospace, medical devices, electronic instruments and high-voltage systems. Over the years, the manufacturing process for Teflon PCB has also improved, which indicates that Viasion can produce more detailed and accurate Teflon printed circuit boards than ever before.
PCB production technology has come a long way, given that its inception and advances in Teflon PCB manufacturing continue to improve. Teflon printed circuit boards come in various shapes and sizes and are increasingly applied in smaller, more complex applications requiring extreme reliability and precision.
