Description

technical field [0001] The invention relates to the technical field of screening tests, in particular to a method, device and computer storage medium for determining the time of an electric aging test. Background technique [0002] Due to the non-repairable characteristics of satellites when they are in orbit, satellites have extremely high requirements for their reliability. Screening the selected components before installation, discovering potential defects and eliminating defective products is the key to ensuring the reliability of satellites. One of the important work links of sex. Among them, electrical burn-in is a commonly used screening method for semiconductor devices used in satellites. Based on the failure laws of commonly used semiconductor devices, they basically conform to the "bathtub curve" (that is, the early failure rate of the device decreases with time, but the failure rate refers to a certain instantaneous failure rate. The probability of failure in the...

Problems solved by technology

Commercial satellites need to pay more attention to cost while considering reliability requirements. Due to the operation mode of short-cycle mass production, products are rolled into production and iterated quickly. Therefore, the electrical aging of semiconductor devices selected by commercial satellites with different life requirements refers to the same test. Time requirements will inevitably lead to excess quality and reliability. Too much energy and resources will be invested in the electrical aging of devices, which will inevitably affect the production cycle and greatly increase production costs. This approach is not suitable for commercial aerospace production models.
