Environmental stress screening (ESS) has become one of the primary approaches in the modern electronic industry to precipitate and eliminate latent or hidden defects in electronic products which are introduced mainly during the manufacturing, assembling and packaging processes. Temperature cycling, plus random vibration (shaking and baking) are the primary processes of ESS. This text presents coverage of the subject, from basic concepts and the historical evolution of ESS, to the statistical and physical quantification of ESS.

Environmental Stress Screening is now being employed throughout the defense industry as a means of precipitating latent part and workmanship defects prior to fielding, with the expectation that improved field reliability and reduced support costs will result. The objective of this study was to develop a quantitative technique for planning, monitoring and controlling the cost effectiveness of stress screening programs for electronic equipment and to prepare a draft military standard based on the developed technique. Latent defects are introduced in equipment through defective parts and deficiencies in the manufacturing assembly process. Design related defects, though not insignificant, are not considered in the techniques developed. Stress screens act on part and workmanship defects with resulting fallout, but since screens are less than 100% effective, some defects escape in fielded equipment. A method for estimating the number of defects initially present was developed and is described later. The effectiveness of stress screens is measured by test strength determined from screening strength equations developed in a previous study and updated in this study based on acutal screening results and test detection efficiency. The question of what is a reasonable number of defects to escape is addressed based on equipment complexity and a tradeoff of stress screening cost and resulting field reliability.

ESS is a technique of testing used for minimizing/eliminating hardware production-line workmanship errors. The application of vibration and temperature environments to items requiring screening can minimize/eliminate such errors as loose wires or parts, cold solder joints, loose screws or nuts, plus other assembly or fabrication type deficiencies. ESS is applied at all stages of fabrication or assembly. The Naval Sea Systems requested that the commercial equipment used on the Precise Integrated Navigation System (PINS) be surveyed for compliance with NAVSEANOTE 3900 and NAVMAT P-9492. This investigation sought to determine the extent to which the PINS commercial equipment manufacturers apply ESS to their equipment during the manufacturing process and to compare commercial practices with Navy requirements in order to discover and document the differences. This report concludes that the limited investigation conducted does not provide a definitive basis for decision. Several alternatives for screening programs are discussed.
