Revolutionizing Millimeter-Wave Technology
DIC Corporation, known for its innovation in chemical technology, has partnered with Unitika Ltd. to create a cutting-edge specialty polyphenylene sulfide (PPS) film. This new film significantly reduces transmission loss at high frequencies, making it ideal for millimeter-wave printed circuit boards utilized in advanced communications systems. The necessity for a material with low dielectric properties has never been more critical, as modern devices increasingly depend on millimeter-wave technology for efficient operation.
Enhancing Electronic Devices with Advanced Materials
Conventional flexible printed circuit boards (PCBs), prevalent in the manufacturing of smartphones and various electronic gadgets, typically utilize liquid crystal polymer (LCP) films bonded to copper foil. Unfortunately, this method often leads to inconsistencies in the adhesive interface, which in turn raises transmission loss. With the shift toward next-generation communication devices that operate within the 30 to 300 GHz frequency range, there is a pressing demand for materials designed to minimize this loss.
Innovative Properties of the New PPS Film
The unique PPS film developed through DIC and Unitika’s collaboration marries proprietary polymerization and compounding technologies with advanced manufacturing processes. This combination not only ensures low moisture absorption but also preserves the flame and chemical resistance characteristic of PPS resins. Additionally, it achieves exceptional dielectric stability and uniform thickness, essential for high-frequency circuit boards. This film’s robustness across a spectrum of frequencies—from 10 to 1,000 GHz—sets it apart from traditional films like LCP, making it versatile across multiple applications, from smartphones to automotive technology.
Compatibility and Processing Advantages
The versatility of the new PPS film extends to its compatibility with several flexible copper clad laminate (FCCL) processing techniques. Whether integrating through sputtering, plating, or adhesive lamination, the film provides a smooth and stable adhesive interface that significantly reduces transmission loss when compared to conventional options like LCP or fluoropolymers. This adaptability will likely lead to widespread adoption in evolving electronic applications.
