Hard failures are observed when the product fails to function properly when under stress and does not return to operating normally when the stress is reduced or removed.
The low maxSoft column represents an assignment where hard checkpoints are created frequently, which guarantees a small re-execution time after a hard failure.
At the high temperature limits in HALT, hard failures tend to occur in poorly designed components and parts that already run hot, such as power supplies.
Six input variables (paste type, wave solder flux, reflow profile peak temperature, wave solder temperature, reflow with nitrogen/air and PCB surface finish) were analyzed against six output factors: number of prior opens (as received), number of soft failures (intermittent during vibration); number of hard failures (persist after HALT); average time to hard failures (for each individual card under test), sum of prior and hard opens (both hard opens); sum of prior, hard and soft opens and the statistical subpopulation (four were recovered).
The detector performed without soft or hard failures, proving to be more than robust when exposed to thermal extremes.
After three days of testing, 23 boards showed hard failures, and the last two had intermittent readings.
Any hard failures induced during the precipitation screen will be detected as well as any soft failures that may be induced by the stresses.
While more work to manufacturer, this technique offers several advantages over traditional designs including a slower, more consistent wear rate, deeper pit depths, and more robustness to ramp down errors and hard failures.
While traditional network management products easily identify network crashes or hard failures, network performance degradations are more difficult to pinpoint and typically require more time from the most experienced network engineers.
With Resonate Commander Solutions, these e-business services can be monitored and managed to ensure the service levels of each transaction, eliminating hard failures and degradation in user experience.
The BMC reports the temperature of the processors, on-board voltages, soft and hard failures as well as board identification information.
