As 5G technology matures, greater capacity, ultra-high-speed data transmission, and very low-latency technologies are required between vehicles, infrastructure, and in-vehicle infotainment systems to achieve economical, safe, and reliable L5 autonomous driving technologies
.
However, 5G systems will require changes not only in the design of electronic components, but also in the types of materials used to make them, which will require the development of new polymers with unique properties
.
5G transmits data faster, requiring materials with thermal and hydrolytic stability
5G transmits data faster, requiring materials with thermal and hydrolytic stabilityTake the autonomous driving application of 5G, for example, which requires access to large amounts of rapidly changing data in near real-time with minimal latency or distortion, simulating human reaction times and ensuring the safe operation of autonomous vehicles
.
Additionally, due to managing the 3X increase in thermal load resulting from data access continual interconnect densification and device miniaturization, coupled with the need to operate at higher processing speeds and frequencies (in the gigahertz range), all of this will Increasing the operating temperature of the device makes it more difficult to dissipate heat
.
This requires the use of materials with a wider range of thermal and hydrolytic stability to ensure consistent performance and data transfer even in the climates of Florida summers and cold, dry Wyoming winters
.
New LCP lower dielectric constant and dissipation factor
New LCP lower dielectric constant and dissipation factorSumitomo Chemical Advanced Technologies (Sumitomo Chemical Advanced Technologies, hereinafter referred to as "Sumitomo Chemical") recently introduced two new liquid crystal polymers (LCPs) with very low dielectric constant and very low dissipation factor (loss tangent), and provide The data helps electrical engineers better understand and model these compounds
.
According to reports, these two LCPs are thermotropic and can be injection molded or extruded to meet the application needs of 5G
.
Required features
.
Because the SR1205L is formulated with a new LCP-based chemistry, it has a lower loss factor, which ensures reliable data transmission even in the gigahertz/millimeter wave frequency range
.
Sumitomo Chemical's testing by a third-party independent agency shows that SR1205L benefits from high hydrolysis resistance, even at high temperature (120°C), relative humidity level (100%RH) and pressure (2 atm), it is better maintains its tensile strength for up to 200 hours
.
Initial testing of the E6205L showed a similar trend
.
According to Sumitomo Chemical, the company can help electrical engineers select the appropriate LCP grade based on specific connector design and thickness requirements, and provide appropriate data to allow engineers to design components better, faster and with higher quality
