Abstract:
1. A method of testing an electronics assembly for a power short circuit, the method comprising: characterizing power off resistance of at least one electronic component of a first packaging level from at least one power boundary of the at least one electronic component, the characterizing of power off resistance occurring prior to placement of the at least one electronic component into an electronics assembly of a second, higher packaging level; determining actual power off resistance of the at least one electronic component after placement into the electronics assembly of the second, higher packaging level, the actual power off resistance being determined from the at least one power boundary of the at least one electronic component; and comparing actual power off resistance of the at least one electronic component in the electronics assembly with the prior characterized power off resistance of the at least one electronic component, and determining therefrom whether a power short circuit exists in the electronics assembly, if so, taking action to prevent potential damage to the electronics assembly resulting therefrom.
