Parameters Varation of Electronic Components in Fuze under High Stress Fields
Dynamic testing experiments and test scheme are carried out to testing the parameter varation of typical carbon film resistors and ceramic capacitors of Fuze under high stress fields—high temperature and high mechanical stress overloading, and the changing law of the components parameter are got in high stress fields, then parameter of components instant instable motion under high mechanical stress overloading is discussed by analyzing experimental results, and found out parameters approximate linear in small range in 25°C～125°C, of nonlinear in large range in the very high temperature of 125°C～350°C conditions, which can offer some reference value to prolong lifetime of military electron device.
