126.96.36.199 Screen Test
Planning and Effectiveness
An effective reliability screening program requires careful
planning that starts during early development. Tradeoff studies are performed
and a complete test specification is prepared and possibly verified for its
effectiveness on prototype hardware.
A key step in specifying an effective screening program is the
identification of the kinds of failure modes that can occur and the assembly
level at which they may be induced. The appropriate screens are those which
are most effective in accelerating the identified modes, whether they are
intrinsic to the part or induced by the manufacturing process.
Due to the varied nature of military electronics equipments and
their associated design,
