    摘要: The process is for manufacturing an electric circuit which comprises an electric element for firing a pyrotechnic device, in which a sheet (1) made from an electrically resistant material is fixed to an electrically insulating support (3), and in which two conducting zones (12a, 12b) separated by an electrically resistant element (13) are then etched on this sheet.This process comprises the following steps:a fine nickel layer and then a fine copper layer are applied to the sheet (1), after which;a hole (7) is pierced through the assembly,a fine copper layer is deposited on the assembly, a protecting mask is deposited in the openings etched in the resistive sheet, a copper layer (10) then a tin-lead layer are deposited in the hole (7) and on both faces of the assembly,the protecting mask is removed and the fine copper layer which was protected by the mask is stripped by chemical action and,the external tin-lead layer is removed by chemical action.The invention applies more especially to improving the reliability and safety of firing an electric munition firing device.

    摘要: In the detonator disclosed, a semiconductor device has its path of major current flow placed in series with a switched power source and a checking apparatus. An explosive adjacent the semiconductor device is set off when the semiconductor device is biased on so it overheats enough to burn out. A checking switch and circuit means test the transistor by biasing it into its low or normal operating range. A meter indicates the operating condition of the semiconductor device without requiring an initiating current. The semiconductor device may be a transistor, a diode, a thyristor, etc.
