Komissarov A.V., Karazeev S.V., Valitov R.R., Shishkin V.V.  Methodology for conducting multi-factor equivalent-cyclic tests for avionics reliability assessment at research and development stage

This paper presents a method for multi-factor equivalent-cyclic testing (MFECT) for avionics reliability assessment at research and development stage. The method's application area and key advantages are discussed. The results of reliability tests form a database. All testing methods and procedures are effective research tools which provide a preliminary assessment of avionics reliability, for example, in terms of degradation of soldered connections of foreign electronic circuitry in BGA-cases, made by Lead-free technology and installed using reballing operations. The MFECT method also addresses the intensification of test object degradation through the use of forced influencing factors of HALT rejection procedures.

Keywords: multi-factor equivalent-cyclic tests, avionics, reliability, infallibility, rejection procedures, R&D.
