Abstract
Official abstract text for this publication.
A pyrotechnic device including at least one layer of a pyrotechnic material deposited on all or part of an electronic circuit, the pyrotechnic material being capable of being triggered by a heating of the circuit due to a failure thereof.
First claim
Opening claim text (preview).
What is claimed is: 1 . A pyrotechnic device comprising: one or a plurality of conductors; and at least one layer of a pyrotechnic material deposited on all or part of an electronic circuit, the pyrotechnic material being capable of being triggered by a heating of the circuit due to a failure thereof, the pyrotechnic effect causing the breaking of said conductor(s). 2 . The device of claim 1 , wherein the explosion of the pyrotechnic material is triggered by a hot spot at the level of the conductor(s). 3 . The device of claim 1 , having a plurality of said conductors electrically in parallel, the explosion of the pyrotechnic material causing the breaking of all the conductors electrically in parallel. 4 . The device of claim 1 , further comprising at least one rigid element capable of being propelled towards the conductor(s) by the pyrotechnic gases. 5 . The device of claim 1 , wherein the thickness of the pyrotechnic material is in the range from 10 to 100 micrometers. 6 . The device of claim 1 , wherein the pyrotechnic material is electrically insulating. 7 . An electronic device comprising: an electronic circuit; and the pyrotechnic device of claim 1 . 8 . The device of claim 7 , further comprising a package at least partially covering the electronic circuit and the pyrotechnic device. 9 . The device of claim 8 , wherein the package is formed of an encapsulation material covering the circuit and the pyrotechnic device and at least partially embedding the conductor(s). 10 . The device of claim 8 , wherein the package is hollow. 11 . The device of claim 7 , wherein the electronic circuit integrates a power switch. 12 . A method of forming the pyrotechnic device of claim 1 , wherein a pyrotechnic material is deposited in the liquid state on the electronic circuit.
