Description

Technical Field

[0001] The utility model relates to the field of chip aging devices, in particular to a test device for accelerated chip aging. Background Art

[0002] Chip HAST accelerated aging test device, the purpose of accelerated life test is to increase environmental stress (such as temperature) and working stress (voltage, load, etc. applied to the product), speed up the test process, and shorten the life test time of the product or system. It is used to investigate and analyze when the wear and service life of electronic components and mechanical parts will occur, what shape the failure distribution function of the service life is, and analyze the reasons for the increase in failure rate. At present, since the chip is exposed, the chemical and physical effects of the environment will affect the test results during the test, and the post-packaging test cannot fully reflect the life of the chip under normal stress, so the chip life cannot be estimated. At present, the academic community also uses nitrogen as the test medium for LED chip life test, but its disadvantages are: ① it is difficult to completely isolate the oxygen molecules in the air; ② the test cost is high; ③ the control accuracy of the experimental thermal stress is relatively low. Among them, an LED chip accelerated life test device with application number "CN201020608332.5" can perform an aging test of the LED chip by energizing and lighting the exposed LED chip in the test environment liquid and controlling the temperature of the liquid; compared with the traditional LED chip aging test, the aging test of the utility model is more efficient, and its aging test results are closer to the aging test results of the actual packaged LED chip, but the device still has certain shortcomings when used: because the chip is placed in the solution and isolated from the air, it is impossible to effectively simulate the chip being affected by factors such as high temperature in an energized and circulating air environment, thereby affecting the experimental results.
