Description

Ignition capacitor aging test detection means

Technical field

This utility model is related to a kind of ignition capacitor aging test detection means, particularly for Aero-Space electromotor The Aulomatizeted Detect of ignition capacitor aging test.

Background technology

Aging test is to be commonly used to reject initial failure product in engineering, the method for improving system reliability.Aging test It is one of screening test of high reliability integrated circuit, its purpose is to screen or reject those circuits for scraping through. These circuits or the defect due to the raw material that used inherently, or introduce as the control of process industry is improper Defect, and these defects can induce the related failure of circuit generation to stress over time.In order to submit to user to make in circuit With front, the circuit for there are these defects is screened out.In screening, need to apply maximum rated working condition or more to circuit Stress, or apply the equivalent screening conditions of equal or higher sensitivity to induce circuit generation failure, and it is rejected. Aero-Space engine ignition capacitor is one of core component of Aero-Space engine ignitor, the property of ignition capacitor Energy, life-span are all related to the quality of engine ignitor, are more related to the security reliability flown each time.So seasoned examination Test is that ignition capacitor is loading the previous requisite strict screening link of engine ignitor.Aging test condition has Six kinds.According to circuit types, working method can select one of which condition to be tested.a）It is stable state, reverse-biased.Suitable for all kinds of Linear and digital circuit.b）Stable state, positively biased.Suitable for all digital circuits and some linear circuits.c）Stable state, power and anti- Partially.Be able to can be biased in maximum power dissipation with reverse bias, outfan suitable for various digital circuits and input（Or in turn） Some linear circuits.d）Actuated in parallel.Suitable for all kinds of circuits.e）Circular oscillator is tested.f）Temperature accelerated test.Have When, in order to accelerate the screening process of circuit, circuit is made in the ambient temperature for substantially exceeding its highest rated temperature（175~300℃） Under the conditions of tested.Now, as temperature is high, circuit abnormality, it is impossible to normal work.
