Manufacturing Methods Report. Static Switch

摘要

This report covers all activity carried out under Contract NO. DAAHO1-75-C-0552, Manufacturing Techniques for Static Switches. The purpose of this contract was to improve the producibility and reliability of the present 2.75-inch rocket launcher intervalometer through the improvement of manufacturing methods and techniques brought about by: a Conversion of all timing functions to solid state circuits; b. Conversion of all switching functions to solid state circuits, c. Provision for the sensing and bypassing of any open or shorted squibs; d. Pilot production of five prototype solid state switches to verify the techniques chosen, and e. Design of an assembly line capable of producing 1000 switches per week. The contract has been concluded with all above tasks successfully accomplished. In addition, a reliability analysis of the solid state circuitry was conducted, an EMI analysis was made, and some EMI testing was done. A detailed investigation into the conversion of the electronic circuitry to one hybrid circuit chip was performed. All of these activities are documented in the report. (Author)
