Development of Substrate Materials for Flexible Printed Circuit Board of 5G Technology- Improvement of Dielectric Performance of Liquid Crystalline Polymer (LCP) -

Abstract

A demand for the 5th generation mobile communication (5G) system is now arising for the purpose of realizing the vehicle autonomous system with super high speed, large capacity, no delaying and multiple simultaneous connection. Since 5G system will use the millimeter wave which is currently used in radar etc., materials used in the 4th generation (4G/LTE) are not suitable due to the large transmission loss, so the liquid crystalline polymer (LCP) is currently attracting considerable attention because of its excellent dielectric properties. We would propose new LCPs designed to realize such performance of 5G system, which are also good matching to the flexible circuit board manufacturers’ equipment.
