Polyimide PCBs

Polyimide PCBs are made from a special plastic material with high temperature resistance, excellent flexibility, and extraordinary mechanical stability. Unlike FR-4 materials, polyimide PCBs are extremely resistant to heat, chemicals, and mechanical stress, making them the preferred choice for high-performance and flexible applications.

Advantages of Polyimide PCBs

Polyimide PCBs are convincing with their extraordinary heat resistance and mechanical stability, making them ideal for demanding applications. They withstand temperatures up to 250°C and are particularly resistant to deformation, vibrations, and shocks. Thanks to their flexible structure, they enable both bendable and stretchable designs, making them the optimal choice for flex and rigid-flex PCBs. They also offer high chemical resistance and are insensitive to moisture and aggressive chemicals. With their low thermal expansion (CTE), they ensure reliable performance, especially in high-frequency applications.

Types of Polyimide PCBs

Depending on the use case, various polyimide variants are available:

  • Standard Polyimide (1st Generation) 6 High heat resistance, ideal for industrial applications
  • Modified Polyimide (2nd Generation) 6 Improved chemical resistance & electrical insulation
  • High-performance Polyimide (3rd Generation) 6 Extreme stability for aerospace, military & medical technology
  • Flexible Polyimide PCBs 6 Perfect for portable & bendable electronics
  • Rigid-Flex Polyimide PCBs 6 Combination of rigid & flexible areas for compact designs

Typical Areas of Application

Due to their excellent material properties, polyimide PCBs are ideal for demanding industries. In aerospace and the automotive industry, they are used due to their heat resistance and mechanical robustness. In medical technology, they enable compact, flexible solutions for portable devices and implants. Also, in the military sector, they convince with their high resistance, while in industrial electronics they provide reliable performance for machine controls, sensors, and IoT applications.
