Why is it necessary to encapsulate?
Populated electronic circuit boards and the components themselves can benefit from a polymeric encapsulant (also called potting) material for several reasons. Fragile components and... Read More
Considerations of thermal expansion in encapsulants.
All encapsulating resins, as well as all other electrical grade materials, have their own unique rate of expansion and contraction over a range of temperatures. This is referred to as the Coefficient of... Read More
