Subject: Unconfirmed Field Failures
When testing returned units (i.e. circuit cards) that have failed at customer sites, occasionally the reported failure or any failure can not be duplicated. Is there any information or rule of thumb regarding these unconfirmed field failure rates? I would be interested in any opinions or experiences.
