Abstract
An electronic device includes an electronic component and a protective shield including a phase change material having a phase change temperature of between 20° C. and 90° C., an antivibration gel having hyperelastic and/or viscoelastic behavior at 20° C., and a separation barrier positioned so as to separate the phase change material and the antivibration gel. The antivibration gel is positioned, at least partly, in contact with the electronic component, and has a thermal conductivity of greater than 1 W/m·K at 20° C.

1-21. (canceled)
An electronic device to be used in a vibration environment having acceleration peaks of greater than 0.1 G and a temperature of which may exceed 90° C. for a period of more than 10 minutes, the electronic device comprising:
- an electronic component;
- a protective shield comprising:
- a phase change material having a phase change temperature of between 20° C. and 90° C.,
- an antivibration gel having hyperelastic and/or viscoelastic behavior at 20° C., and
- a separation barrier positioned so as to separate the phase change material and the antivibration gel,
- the antivibration gel being positioned, at least partly, in contact with the electronic component, and having a thermal conductivity of greater than 1 W/m K at 20° C.
