Power-off testing
Power-off testing is often necessary to test the printed circuit assembly (PCA) board due to uncertainty as to the nature of the failure. When the PCA can be further damaged by applying power it is necessary to use power off test techniques to safely examine it. Power off testing includes analog signature analysis, ohmmeter, LCR Meter and optical inspection. This type of testing also lends itself well to troubleshooting circuit boards without the aid of supporting documentation such as schematics.
Typical equipment
- Analog signature analysis*
- Huntron Tracker*
- Automated optical inspection
- LCR meter
- Machine vision
- Ohmmeter
gollark: Those are purely hypothetical.
gollark: Well, yes, I suppose we do use advanced ideatic/memetic devices to sift hëavserveric discussion and emotion from the noösphere and expand heavserver.
gollark: "Rate at which they create heavserver"/"How often someone declares that they hate 'heavserver' and always avoid it"
gollark: > 'Heavserver' is just 'people being upset', when someone says they're always surrounded by heavserver and they just ignore it, it starts to make sense that their strategy might be backfiring.I feel like this is somewhat inaccurate.
gollark: Wait, user was on heavserver?
