The following table shows the predicted values for reliability as Mean Time
Between Failures (MTBF) and Failures Per Million Hours (FPMH) as calculated
for an SBC330‐15304.
The predictions are carried out using MIL‐HDBK‐217F Notices 1 and 2, parts
count method. To complement the 217 failure rates, some manufacturers' data is
included where appropriate; Q values have been modified according to industry
practice.
