text: When potting a circuit board that uses surface-mount technology, low glass transition temperature (T g ) potting compounds such as polyurethane or silicone may be used, because high T g potting compounds may break solder bonds through solder fatigue because by hardening at a higher temperature the coating then shrinks as a rigid solid over a larger part of the temperature range thus developing greater force.
