  Computerized integrity test of an electronic product hardware interface and
product probing validation are considered. Integrity testing is based on a
current voltage characteristic measurement, when a small voltage and/or current
stimuli are applied to the product pads including power supply circuitry pads,
so that the product is not normally powered on. Test fixture needles validation
is a part of a self test maintenance scenario designed to predict deterioration
of product probing.
