摘要:

AbstractProduct reliability testing of a video monitor, incorporating rapid thermal cycling, highlighted an interesting problem with failure of a small transformer on the analogue card, causing a severe shimmer of the display. A theoretical model describing this problem is presented, and shows how such an approach can assist in understanding the failure mechanism as well as assisting the resolution of certain dilemmas surrounding it.
