  Contaminants and Moisture Can Disrupt Your Electronics Course description This course provides details about the root causes of many poorly understood electronic failures. The chemistry encountered in many end-use environments will be covered at length. We will discuss sources of contamination and the adverse effects of contamination on high-rel electronic systems. This understanding will enable participants to create more complete and accurate testing protocols for evaluating the true long-term reliability of new electronic designs, materials and processes. This understanding will also help organizations to troubleshoot production and field problems with existing electronic designs, materials and processes. Illustrated lectures and classroom discussion reveal the dangerous yet little recognized synergistic (that is, combined) field conditions of contamination + moisture, especially when field thermal and vibration stresses are added. These conditions will cause the premature failure of many forms of allegedly strong and highly reliable (but actually weak and unreliable - vulnerable) electronic equipment. Current production testing and screening protocols (as well as reliability studies) largely ignore these dangerous combined environments. Ever-smaller feature sizes and separations, plus smaller signal levels and higher frequencies all act to increase vulnerability to contaminants and moisture. Without proper testing, too much blind trust is being placed in supposedly safe conformal coatings and other protective measures. Subtle changes in test protocols, which can cause major differences in the results, will be discussed, along with some of the limitations of present measuring and monitoring equipment. A major topic: the optimum point in the production cycle at which to screen. Objectives High reliability electronic systems utilizing new designs and expanded systems integration are required to meet performance based specifications. Contracts should include some form of laboratory validation method prior to (1) awarding the contract, (2) making milestone payments, and (3) assessing penalty clauses if fielded equipment fails to perform fully. Upon completion of this course, participants will realize the potential cost savings of highly accelerated life testing (HALT) that combines contamination with traditional testing protocols. The course will enable participants to generate more realistic test data needed for (1) predicting long term reliability and for (2) predicting warranty/infant mortality.

  Optimizing Electronics Vibration HALT, HASS, ALT and ESS A three-day interactive workshop aimed at shortening the time required for electronics design, vibration testing and (when weaknesses are found) corrective action. This course applies to vibration of electronics at system, box or circuit card level. Methods can also be used in the design and testing of electronic components to meet vibration standards or desired capabilities. Discussion of simple methods and animations assist participants understand the complex responses of their electronics to laboratory and to field vibration. "Vibration test efficiency" is a new term, used here to illustrate recent improvements over the past slow "learning curve" for vibration knowledge. Since vibration life of most electronics is dependent on response at circuit card level, methods concentrate on the fatigue damage from PCB modal response. The purpose of this course is to simplify the complex field of vibration of electronics and make results understandable. 1% Efficiency? Tests can determine fragility limits of test samples. But few tests supply any further information (beyond pass/fail). Why? Because test measurements can't fully describe failures. Most tests miss most of the valuable information that is (with this course) readily available. Early Attempts In the 70's and 80's, relatively simple mathematical methods were developed to predict PCB vibration life capabilities. Why? Because few companies could afford that era's high-speed computer systems and the technical expertise needed to analyze vibration. Those early methods, still used by many, provide guidelines that sometimes work, but they never provide product understanding. And all too often, such guidelines outright fail, at great expense - the expense of design and production of an unreliable product. But since then, the cost of high-speed computer power has dropped at a rate of about 50% per year. The compounded cost savings of the mid 80's high-speed computer is over 99.99%. One of the best-kept secrets of certain large companies is their ability to produce reliable electronic products at low cost. How? They are able to fully understand vibration of their electronics through detailed analysis. Such companies rarely share their reliability secrets with competitors. But now, with this course, every company can afford high speed analysis support of its testing. Test Efficiency? Let's define test efficiency as dollar value of information gained divided by dollars of test cost. If you run a test program without analysis, your numerator is near zero. Adding modern technology analysis can immeasurably increase your "information gained" numerator. Every test performed without detailed posttest analysis throws information away and wastes money. Rather than throw it away, capture that information and use it to save many design and production problems. Detailed Analysis? The "design life" of any system is defined by its weakest part based on the part's local exposure. Since vibration damage of circuit cards is dominated by cyclic stresses (caused by modal vibration), analysis should concentrate on accurately quantifying the stresses experienced by every component. Design life is limited by accumulated fatigue damage. Taking advantage of the speed of today's PCs, companies without prior experience can use this course to understand and avoid vibration-induced failures. For DATES AND LOCATIONS see web page More ...
  Vibration Testing: Theory and Practice Vibration Testing: Theory and Practice not only shows how to avoid the pitfalls inherent in using modern instruments and methods but also covers all the important elements involved in conducting vibration tests, and builds an understanding of the theory through practical applications in laboratory and field environments. Based on the author's 30 years of experience in vibration testing and research, this clearly written, logically presented book: Provides a review of the fundamentals of vibration theory Brings the theory and practice of vibration testing up to date with all current instrumentation and research data Covers transducers, their calibration as well as their limitations Includes a complete chapter on vibration test specifications Helps develop a sense of how instruments work individually as well as how they function as part of a testing environment Includes practical examples that can be used for personnel training purposes Addressing concerns of both experimental researchers and product testers, and covering a wide range of field and laboratory situations, Vibration Testing: Theory and Practice is an extremely useful book for anyone striving to achieve meaningful results in vibration testing. Vibration testing is used to analyze the integrity of systems in a variety of applications that range from circuit boards and aircraft to steam turbines and home appliances. Conducting these tests in either the field or laboratory involves the use of data analyzers, instruments, and vibration exciters. The use of equipment and interpretation of test results require considerable understanding of vibration phenomena as well as analysis and experimental concepts. Consequently, the user of this equipment can be the dominant influence on the quality of test results. Vibration Testing: Theory and Practice is a step-by-step guide that shows how to obtain meaningful experimental results via the proper use of modern instrumentation, vibration exciters, and signal-processing equipment, with particular emphasis on how different types of signals are processed with a frequency analyzer. Also included are techniques for reading test results effectively and a discussion of how the test system's own dynamics can influence test results. Using practical lessons to introduce the theoretical aspects of vibration testing, the book covers all basic concepts and principles underlying dynamic testing, explains how current instruments and methods operate within the dynamic environment, and describes their behavior in a number of commonly encountered field and laboratory test situations. Vibration Testing: Theory and Practice deals with a wide range of product and production testing involving vibration, acoustics, and noise problems in the vibration-testing environment, whether relating to industrial applications or experimental work. It is an invaluable resource for graduate students, research-ers, and practicing engineers in aerospace, mechanical, and civil engineering. More ...
