PCB flexible materials
PCB flexible materials, also known as flexible dielectric substrates, are the foundation of flexible printed circuit boards (flex PCBs). These materials provide the flexibility and durability required for flex PCBs to conform to various shapes and withstand repeated bending.
Polyimide is a superstar material for creating certain types of PCBs, especially those needing top-notch flexibility and resilience. Unlike standard rigid PCBs, polyimide substrates can bend and conform without breaking, making them ideal for wearable devices and applications with limited space. This amazing material also boasts exceptional heat resistance, meaning your PCBs can handle scorching temperatures without malfunctioning. That’s not all, polyimide is a tough cookie, offering superior strength and chemical resistance for long-lasting performance in demanding environments. So, if your PCBs need to be flexible, tough, and function in high heat, polyimide is the perfect substrate to take your electronics to the next level.

The ESPANEX series
The ESPANEX series of copper-clad laminated sheets for flexible PCBs was developed using Nippon Steel Chemical's proprietary technology. This series stands out for its lack of adhesive due to the utilization of low-expansion polyimide. ESPANEX has garnered an excellent reputation as an essential component in circuit boards for mobile phones and other devices. Also in drive circuit boards for LCDs (liquid crystal displays), where high performance and reliability are paramount. As semiconductors progress towards higher densities and integration levels, demands are becoming increasingly stringent with regard to rates of dimensional change, thermal resistance, electrical properties, mechanical properties, and other factors. ESPANEX, which enhances these characteristics, has capitalized on this trend and now holds a significant share of the global two-layer CCL market.
