  • Accelerative effect analysis of quantitative environmental stress screening

    Environmental stress screening is an effective method to eliminate the potential defects of electronic products. In order to improve the efficiency and effectiveness of environmental stress screening, the acceleration effect was derived and analyzed based on the quantitative environmental stress screening mathematical principles of GJB/Z34. Then the high-temperature aging, temperature cycling, and random vibration acceleration effect evaluation model was proposed, and the test times under conventional stress and accelerated stress were obtained respectively. Finally, the stress acceleration factor was calculated according to the test time between conventional stress and accelerated stress and an example given which proved that the screening was effective.

  • Economic cost modeling of environmental-stress-screening and burn-in

    The electronics industry is highly competitive. The introduction of new advanced integrated circuits continues. The manufacturer must develop a product with adequate life cycle, high quality and low failure rate in the specified time period. Environmental stress screening (ESS) is widely used in the electronics industry to assist in eliminating early or patent failures. The bathtub curve is a common model for the failure rate of a population. The classic bathtub curve has three parts: infant mortality; useful life; and wearout. However, some electronic products have latent defects which are not detected by conventional inspection or functional testing, and occur during the product useful life. Most electronic systems have finite useful life. As a result, technology obsolescence is of concern and should be considered, This paper uses a new interpretation and development of the bathtub curve that integrates: (1) latent failures; and (2) the concept of obsolescence, by constructing an integrated cost model used to determine both optimal burn-in and ESS times in the same environment.

  • Electronic-module environmental-stress-screening data-evaluation technique

    This report has provided a reliability engineering analysis technique to support optimization decisions for a production environmental stress screening (ESS) program and demonstrated its use. The important groundrules used in this analysis are: (1) a disciplined approach to the ESS process is required for the results of this analysis to be effective; and (2) the failures per thermal cycle should be distributed equally throughout the cycle in order to represent a realistic scenario. The benefits associated with the analysis technique include: (1) the parameter, "failures per thermal cycle", has a simple accounting method and is easy to accurately collect; and (2) the tools are PC based and facilitate timely reaction to management requests. The observations made during the generation of this report are: (1) all ESS failures must be analyzed for root cause and effective corrective action; (2) the input data to the analysis technique must be completely understood so that the results of the optimization decision process are prudent; and (3) feedback from field performance is a vital element in the optimization process.

  • Environmental stress screening for a massively parallel vision computer

    AISI began experiencing a severe field reliability problem with their computers. There was a single point source of failure in the systems in which they were incorporated. An issue with programmable array logic (PAL) had driven the customer return rate to approximately 45% and caused severe production problems for the ultimate users of the computers. The legacy screening process used by AISI was ineffective at screening out the problems. The limited amount of failure analysis performed was inconclusive at identifying root cause of the failures. A screen was developed based on generic information on technology failure mechanism and circumstantial evidence gathered by AISI. The resultant screening used both temperature and voltage stress. Combined with part level screening and change of suppliers the customer return rate was reduced to 1%. Further improvements for part level screening were developed using Iddq as a parametric screen. The board-level screening program required a capital investment of only $50,000. Part screening increased the price of the parts by an additional 10%.

  • Critical review of U.S. Military environmental stress screening (ESS) handbook

    Environmental stress screening (ESS) is a process to eliminate defects caused by materials and manufacturing variations in electronic products by a 100% screening, with the goal to eventually improve manufacturing processes that cause the defects. MIL-HDBK 344A- Environmental Stress Screening (ESS) of Electronic Equipment describes a quantitative approach for planning, monitoring, and controlling an ESS process. This handbook was last updated in 1993 but is still widely used today within and beyond the military and aerospace industries. While the processes and overall philosophy of ESS are well presented in the handbook, the mathematical foundations and the data it uses have become obsolete over the years. These concerns are explained with a thorough analysis of the initial defect estimation and screening strength estimation steps described in the handbook. With the rapid evolution in electronics technology, the handbook's estimation methods are meaningless if not counterproductive for the planning of an ESS program for today's electronics systems. Based on the critical concerns presented in this article, we urge the U.S. Department of Defense to cancel and stop use of MIL-HDBK 344A.

  • ESS profiles with step stress level

    Environmental Stress Screening (ESS) is usually referred to the process of exposing a product to environmental stresses for detecting and eliminating latent defects made in manufacturing process. The common ESS profiles are using thermal cycling, random vibration or their combinations as the screening stresses. Various guidelines and standards have been available for determining an ESS profile. Nevertheless, there are cases that the standard ESS profiles may not be efficient enough to detect the latent defects in some manufacturing process. This paper reports the results of one industrial project on the ESS profile design for circuits. In the project, a comparative study was carried out for the evaluation of the ESS strength under the ESS profiles with incremental step stresses (ISS). The ISS profile under the study is firstly to implement a step thermal cycling and then perform the test with two screening stimuli concurrently: ordinary thermal cycling and random vibration of step increasing intensity levels. For the purpose of the comparative study, the ESS test samples were consisted of two groups A and B that were made at two different levels of manufacturing: soldering by skilled and unskilled workers, respectively. The comparative study shows that the ISS profiles are effective for exposing the latent defects in sample group A and B. Based on the project results, an ESS profile is recommended in this paper.

  • Planning and optimizing environmental stress screening

    Environmental stress screening (ESS) is widely used in the electronics industries as a means to remove early failures. It is a process that calls for proper planning as inadequate duration is ineffective while prolonged screening can incur unnecessary cost. This note describes an approach utilizing mathematical programming to ensure that the right amount of screening is in place at each assembly level. The factors considered include the screening cost and desired operational reliability.

  • Optimization model for environmental stress screening of electronic components

    Environmental stress screening (ESS) is a technological process to reduce the costly early field failure of electronic components. This paper builds an optimization model for ESS of electronic components to obtain the optimal ESS duration. The failure phenomena of ESS are modeled by mixed distribution, and optimal ESS duration is defined by maximizing life-cycle cost savings under the condition of meeting reliability requirement.

  • On the Implications of R&M 2000 Environmental Stress Screening

    The US Air Force R&M 2000 ESS policy differs little from that of the other armed services in that the same two primary screens, temperature cycling and random vibration, are employed at the module and end-item levels. Two of the screening parameters, 25 cycles and 30 °C/minute, for module-level temperature-cycling exceed the norm. What is different is the requirement for part defect rates, 1000 parts per million (ppm) beginning in 1986 October and 100 ppm in 1989 October. Defense contractors will have to figure out how to work with their part suppliers, or develop in-house screening methods to get part defect rates down to 100 ppm. The Air Force has published a handbook [1] and a companion guideline document [3] for implementing the ESS policy. The handbook contains procedures for addressing the four problems: 1) estimating the fraction of defects entering the manufacturing process, 2) estimating the fraction of defects generated during manufacturing, 3) assessing the effectiveness of stress screens, and 4) determining an acceptable level of defects remaining on delivery. The ESS policy and guidelines can result in effective application of ESS and improved field reliability.
