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 new Smart-UPS RMXLT and RMT3U lowers costs of downtime by reducing the number of hard failures
and eliminating a large portion of NTF (No Trouble Found) service calls.
After three days of testing, 23 boards showed hard failures
, and the last two had intermittent readings.
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.
future hard failures
before they become unrecoverable.
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.
