For example, a laminate is characterized by its coefficient of thermal expansion (CTE) in all three directions (length, width, and thickness) as well as its thermal coefficient of dielectric constant.
In this paper, the Thermal–Mechanical-Stress-Creep (TMSC) effect during thermal processes from room temperature (RT) to 200 °C is modeled and measured, in which an Au-cantilever-based RF MEMS switch is selected as a typical device example.This paper investigates thermal effects through both numerical simulation and temperature chamber testing. When temperature fluctuates, previous sensor design (with a glass microfiber-reinforced PTFE substrate) shows relatively large variation in resonance frequency.
Temperature change causes the fingers of the capacitor to move because of the material thermal expansion. The movement of the fingers changes the overlapping area of the plates, which, in turn, changes the capacitance, accordingly. These sensors have been implemented in harsh or enclosed environments, where remote measurements are preferred. Accurate material properties are critical to obtain accurate results. In particular, thermal expansions are highly nonlinear with temperature and must be adjusted to account for the shift in reference temperature (i.e. braze alloy solidus temperature) when using mean thermal expansion values. In this study, novel configurations of high-entropy ceramic (HEC) materials were explored by predicting their coefficient of thermal expansion (CTE) using machine learning (ML) and high-throughput screening.
