| 摘要 |
The present invention relates to the field of electropyrotechnic initiators comprising a thick-film multifoil circuit.The electrical circuit is photoetched on an insulating support (16). It consists of a resistive first foil having a central part (17) of constant width. This first foil is covered, except on the central part (17), by two conducting areas (28, 29) made of copper. The circuit (18) has an outline consisting of curved lines whose radius is greater than 7x10-4 m and whose shortest distance from the edge of the support (16) is at least 35x10-5 m.Such an initiator has an enhanced electrostatic discharge resistance.
