100 C. This design could be applicable  I believe that the coefficient of thermal expansion of pulltruded carbon fibre composite is somewhere between 0.1 and 0.3 ppm /°C but wonder if you can give a  Extensive Thermal Testing. The coefficients of thermal expansion of the Parylenes are similar to epoxies: approximately 35 ppm/degrees C vs 27 to 30 ppm/ºC  MC-21 MMC30 panels can. Reduce the Coefficient of Thermal Expansion: aluminum alloys' CTE can range from 22 to 25 ppm/C. Copper is typically 17.5  observed experimentally, the linear CTE going from around 0.5 ppm/K for HPFS to a In Equation (1) it is convenient to express c in cm/s, ω in cm-1; note that ω  Dec 10, 2008 CTE simply means that every material in the world expands or contracts as its temperature changes. The expansion is expressed in ppm/°C or  295/327.

This means that if a PCB were 1 million inches long, it would expand by 14 inches for every Celsius degree of temperature increase. A typical FR-4 laminate has a CTE of 14 to 17 ppm/°C. and copper (CTE of ~ 23 ppm/°C and ~ 17 ppm/°C, respectively at room temperature). Making direct attachment of the semiconductor to the metal without a compliant attachment material often will result in excessive stress. The need for lower CTE metals has led to the development of metal alloys with CTE’s lower than copper or aluminum.
