Potting (electronics)

Potting (electronics)

In electronics, potting is a process of filling a complete electronic assembly with a solid compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents. Thermosetting plastics are often used.

Most circuit board assembly houses coat assemblies with a layer of transparent conformal coating rather than potting. [] Conformal coating gives most of the benefits of potting,and is lighter and easier to inspect, test, and repair.

When potting a circuit board that uses surface-mount technology,Potting Solutions recommends using low Tg potting compounds such as polyurethane or silicone, because high Tg potting compounds may break solder bonds as they harden and shrink at low temperatures.
