Polyimide material is most commonly used in the flexible printed circuit boards. The polyimides that are used in the flex PCBs are generally imide monomer polyimides. The thermal conductivity of this material is far better than that of the FR4 material. The following beneficial features of this material, make it a perfect choice for PCBs in a wide range of applications:
Excellent Tensile Strength
Very Stable over a Wide Temperature Range
Exceptionally Resistant to Chemicals
Amazing Electrical Properties
Vast Operating Temperature Range from -200 °C to 300 °C
Excellent Heat Resistance
