Introduction

5G (fifth-generation mobile communications system) is a new mobile communications system featuring high speed, high capacity, low latency, and multiple simultaneous connections. The adoption of 5G will enable the instantaneous review of vast amounts of big data, such as data collected by IoT devices, and AIbased analysis and training of AI with this data. This, in turn, will accelerate the development of remote healthcare services, home healthcare, automated driving, and congestion forecasting and introduce new technologies and servicesinto our lives. The growth of 5G requires that smartphones and other terminal devices use high-frequency printed circuit boards (PCBs) with good electrical characteristics. This need has created a growing interest in new materials that can replace FR-4 (a PCB substrate material made of glass cloth impregnated with epoxy resin) and glass polyimide substrates that use polyimides. Two typical examples of these replacement materials are liquid crystal polymers (LCPs) and fluoropolymers. This article describes using Fourier-transform infrared spectroscopy (FTIR) to evaluate structural changes in fluoropolymers upon heating and thermogravimetry-differential thermal analysis (TG-DTA) to evaluate the change in mass of fluoropolymers upon heating.
