摘要:
为了提高半导体桥(SCB)火工品的抗射频干扰性能,采用具有负温度系数(NTC)特性的热敏电阻与火工品并联。该文采用红外显微测温、1A1W5min试验、射频感度试验及电容放电发火试验。试验结果表明:热敏电阻可以降低SCB桥区温度;在1A1W5min、射频注入22 W条件下不发火;且射频实验后,电容放电可以使其正常发火。NTC热敏电阻可以有效地提高SCB的抗射频性能,且不影响火工品的发火性能,是火工品抗射频干扰可行的新方法。
Abstract:
In order to improve the anti-radio frequency interference performance of semiconductor bridge(SCB)initiators,thermistors with the negative temperature coefficient(NTC)are used to be in parallel with the SCBs.Infrared micro-thermometric technology,1A1W5min experiment,radio frequency(RF)sensitivity experiment and capacitor discharge firing experiment are used.The research results indicate that the NTC thermistor can decrease the temperature of bridge areas.SCBs in parallel with thermistors do not fire under 1A1W5min and 22W RF power.After the RF sensitivity experiment,capacitor discharge can normally ignite the SCB initiators.NTC thermistors can effectively improve the anti-RF interference performance of SCBs and do not affect the firing property.Adopting NTC thermistors for the RF reinforcement is a novel and feasible method to protect SCB initiators.
