Panasonic Corporation announced that its Industrial Solutions Company has commercialized R-5410; a halogen-free, ultra-low transmission loss Multi-Layer Circuit Board (MLCB) material suitable for millimeter-wave antennas. Mass production will begin in March 2021.
The millimeter-wave radar is a key technology for automotive, telecommunications and other industries. These systems form the basis for the driving environment recognition platforms which enable Advanced Driver-Assistance Systems (ADAS) technology.
With the aim of achieving enhanced Mobile BroadBand (eMBB), massive Machine Type Communications (mMTC) and Ultra-Reliable Low Latency Communications (URLLC) in 5G communication systems, wireless communication base stations also use millimeter-wave bandwidths with beamforming technologies based on massive-element antennas. The rapid adoption of millimeter-wave radar has increased the performance requirements for high-frequency circuit boards used for wireless communications. Demand has increased for multi-layer circuit board materials that exhibit low transmission loss in the millimeter-wave band.
Historically, fluoropolymer circuit board materials have been primarily used for manufacturing antenna circuit boards. However, these fluoropolymer materials are thermoplastic and can be difficult to process into multi-layer constructions. The newly developed R-5410 Halogen-free Ultra-low Transmission Loss Multi-Layer Circuit Board Material is a prepreg material made from a unique non-fluoropolymer thermosetting resin system. This new prepreg enables multi-layer antenna constructions using industry-standard circuit board lamination manufacturing processes and equipment. This feature increases the flexibility of high-frequency circuit board designs, enabling compact and high-density modules integrated with antennas at reduced material and processing costs and improving the efficiency of antenna performance.
Panasonic's new halogen-free ultra-low transmission loss multi-layer circuit board material has the following features:
Basic specifications: Core material: R-5515, Prepreg: R-5410
Suitable applications: Millimeter-wave antenna circuit boards (eg: automotive millimeter-wave radars, wireless communication base stations), high-speed transmission circuit boards.
