Study on Delamination Variation Trend of Two Plastic Packaging Devices in Combination Reliability Test

摘要

Delamination is an important failure mechanism of plastic packaging devices. In this paper, the delamination variation trend of two kinds of plastic packaging devices were traced through combined reliability test. Test condition was designed based on the actual operating condition of the device. C-SAM inspection was carried out after each test. It is observed that delamination was expansion during reliability test in one kind of plastic packaging device, and initial delamination was disappeared in another kind. Finally, two kinds of devices passed all qualification test, which meet the requirements of application. The results of this paper can be used as a reference to judge and control the influence of plastic packaging device delamination in other reliability verification test.
