Problems solved by technology

Most of the current micro-S&A systems are processed by MEMS technology, which realizes the function of explosion-proof and environmental protection in the system. A few products with high integration have added MEMS electric actuators or pyrotechnics on the basis of the above-mentioned products. Actuators and other micro-movable devices form a micro-S&A system with remote release, two environmental force release insurance and explosion-p

Abstract

The invention relates to a safe, arm and fire integral micromodule designed based on microsystem integrated technology. A core structure of the safe, arm and fire unit is processed to be a SAF integral chip structure by MEMS-CMOS machining process and through design for the safe, arm and fire principal; the integral micromodule can be largely reduced in size while the traditional safe, arm and fire function are simultaneously implemented through design for the electrical connection style of the SAF integral chip, design for primary explosive sequence of the SAF integral chip, priming composition, primary explosives and a flyer; the integral thickness without battery of the micromodule is less than 1cm, size is less than 1 cm<3>; the micromodule can implement a plurality of functions as timed igniting, impact initiation and self-failure etc.

Description

technical field [0001] The present invention relates to a core micro-component, specifically a micro-component integrated with safety, arm and fire (Safe, Arm and Fire) designed based on micro-system integration technology. Background technique [0002] Safe & Arm components are the key mechanisms to ensure the safety of normal functioning and normal service processing. In recent years, with the development of micro-system integration technology, micro-system integration technology has been applied to the design and manufacture of S&A systems It is a hotspot of current and future S&A technology research. The application of microsystem integration technology brings possibility to reduce the size of S&A system, improve reliability and add new intelligent functions. Most of the current micro S&A systems are processed by MEMS technology, which realizes the explosion-proof and environmental protection functions in the system. A few products with high integration level have added...
