Abstract
An encapsulated device and method for making such encapsulated device containing a bladder disposed between a wall of the case and the encapsulant. The bladder defines a space devoid of encapsulant and contains a collapsible insert such as an open cell foam material, thereby allowing the unimpeded thermal expansion of the encapsulant. By reducing thermal expansion stresses on the encapsulated devices, the reliability of the encapsulated device is improved.
