Defining Accelerated Test Requirements for PWBs: A Physics-Based Approach

Abstract:
Typically thermal cycle test requirements for printed wiring boards (PWBs)
are somewhat arbitrarily established for a particular product. Many programs
simply default to a standard test without much quantitative analysis. With
product reliability and cost management pressures, developing realistic
accelerated test criteria is vital. The procedure described in this paper is
based on substantial measured field environment data, a validated
acceleration model with a generalized product definition, and
statistically-based test requirements. While the particular example is for
commercial air transport avionics, the proposed procedure is easily
extensible to other high reliability applications.
