Why Thermal Decomposition (Td) Is Important as a PCB Property
SpletConclusion: CTEz is far more important than Tg with respect to z-axis expansion. A higher Tg material does not guarantee a higher thermal performance with respect to lead-free … SpletTd is also called thermal decomposition temperature. This is the temperature whereby a Circuit board material chemically decomposes (losing about 5% of its mass) is known as the decomposition temperature. Td is measured in degrees Celsius, just like glass transition temperature Tg. doxycycline for hair loss
