Kapton PCB, also known as flexible PCB, is a very important type of PCB in the modern electronics industry with unparalleled flexibility.
What is Kapton PCB?
Kapton is a registered trademark of polyimide film developed by DuPont with excellent thermodynamic and electrical properties. Kapton PCB refers to PCB with Kapton film as the base material.
This material is used to manufacture flexible circuit boards that can withstand extreme conditions, making it an ideal choice for medical, aviation, and consumer electronics.
Features of Kapton PCB:
1.Can be bent, folded, and twisted.
2.Can operate in high temperature environments from -269°C to +400°C.
3.Resistant to chemicals and radiation.
4.Very space-saving, suitable for aerospace and medical equipment with limited space.
Compared with FR-4 PCB, Kapton PCB is different:
1.The heat resistance temperature of Kapton PCB is as high as 400°C, which is much higher than 260°C of FR-4.
2.Kapton material has very low dielectric loss compared with FR4.
3.Thin and light, small surface area, light volume, and foldable.
Conclusion
Kapton PCB is actually more called flexible PCB, which is widely used in new-age electronic products such as aerospace, energy, and medical.
