Abstract
A silicone gel encapsulated integrated circuit (12) is placed in a container, the container being partially filled with a silicone elastomer (16) which is much more rugged than the gel. After the elastomer (16) hardens, it completely covers the gel encapsulation (14) and protects it and the integrated circuit device from the effects of rough handling. The gel, however, gives all of the protection from the external environment that it would in the absence of the elastomer encapsulation.
