Why Choose Polyimide?
Polyimide (PI) is a polymer material known for its exceptional thermal stability and mechanical strength. As a flexible substrate, it maintains consistent performance across a wide temperature range from -200°C to +260°C, making it an ideal choice for manufacturing PI Flexible PCBs.
We offer various types of polyimide materials to meet diverse application needs:
- Pure Polyimide: Halogen-free, suitable for high-temperature soldering processes.
- Filled Polyimide: Enhanced mechanical strength, improving drilling and lamination stability.
- Low-Flow Polyimide: Ideal for lamination designs requiring high structural integrity.
- Copper Clad Polyimide: Combines conductivity and mechanical strength by applying copper to the surface of a polyimide film.
These materials form the foundation of our high-performance polyimide flexible circuit solutions, ensuring stable operation even in extreme environments.
