Similarly, at 150℃ and 7 MPa, the deformation rate is 2.1% in the Z-axis, showcasing the material's dimensional stability under pressure and heat. The moisture absorption of the RT/duroid 6006 is an impressively low 0.05%, as determined by D48/50℃ testing with a thickness of 0.050" (1.27mm), ensuring its reliability and stability in humid environments. Moisture absorption is the total weight of the circuit board material absorbing external water, which is measured in percentage. At higher frequencies the smaller the better, with a typical value of between 0.1% and 0.2%. The water absorption of RT/duroid 6006 performs as low as 0.05%. Regarding thermal conductivity, the material exhibits a value of 0.49 W/m/k at 80℃, indicating good heat dissipation capabilities. The coefficient of thermal expansion for the RT/duroid 6006 is 47 ppm/℃ in the X-axis, 34 ppm/℃ in the Y-axis, and 117 ppm/℃ in the Z-axis at 23℃ and 50% RH, reflecting its ability to withstand temperature changes without significant dimensional variations. RT/duroid 6006 material's thermal decomposition temperature (Td) is 500℃, as determined by TGA testing, ensuring its stability in high-temperature environments. With a density of 2.7 g/cm3, the RT/duroid 6006 strikes a balance between lightweight design and robust performance. In terms of specific heat, it measures 0.97 j/g/k (0.231 BTU/ib/OF), providing insights into its heat absorption and retention capabilities.
