Abstract

The work aims to study the application of reliability enhancement testing technology in airborne electronic products to provide engineering practice support for improving the reliability level of airborne electronic products. By selecting high-failure airborne electronic products, and through the brief introduction of the principle, the basic flow and test methods of reliability enhancement testing, low-temperature stepping, high-temperature stepping, rapid temperature change, vibration and comprehensive stress tests far exceeding design requirements and specifications were carried out to actively trigger product defects and iteratively improve them. Through experiments, it was found that high-failure airborne electronic products had deficiencies in terms of equipment selection, circuit design, strength design and process reliability. By formulating rectification measures and further improving the design, the products passed the tests without faults, and the inherent reliability of the products was enhanced. Through the comparison of test results, it is found that the reliability level of high-failure airborne electronic products is increased by approximately 160%, the working limit temperature, vibration resistance and environmental suitability of the products are improved and enhanced significantly. This further demonstrates that reliability enhancement testing has significant engineering value in defect identification and product optimization.
