This book presents a systematic approach in performing reliability assessment of solder joints using Finite Element (FE) simulation. Essential requirements for FE modelling of an electronic package or a single reflowed solder joint subjected to reliability test conditions are elaborated. These cover assumptions considered for a simplified physical model, FE model geometry development, constitutive models for solder joints and aspects of FE model validation. Fundamentals of the mechanics of solder material are adequately reviewed in relation to FE formulations. Concept of damage is introduced along with deliberation of cohesive zone model and continuum damage model for simulation of solder/IMC interface and bulk solder joint failure, respectively. Applications of the deliberated methodology to selected problems in assessing reliability of solder joints are demonstrated. These industry-defined research-based problems include solder reflow cooling, temperature cycling and mechanical fatigue of a BGA package, JEDEC board-level drop test and mechanisms of solder joint fatigue. Emphasis is placed on accurate quantitative assessment of solder joint reliability through basic understanding of the mechanics of materials as interpreted from results of FE simulations. The FE simulation methodology is readily applicable to numerous other problems in mechanics of materials and structures.

Solder Joint Reliability Prediction for Multiple Environments will provide industry engineers, graduate students and academic researchers, and reliability experts with insights and useful tools for evaluating solder joint reliability of ceramic area array electronic packages under multiple environments. The material presented here is not limited to ceramic area array packages only, it can also be used as a methodology for relating numerical simulations and experimental data into an easy-to-use equation that captures the essential information needed to predict solder joint reliability. Such a methodology is often needed to relate complex information in a simple manner to managers and non-experts in solder joint who work with computer server applications as well as for harsh environments such as those found in the defense, space, and automotive industries.

Download Assembly and Reliability of Lead Free Solder Joints Book in PDF, Epub and Kindle
This book focuses on the assembly and reliability of lead-free solder joints. Both the principles and engineering practice are addressed, with more weight placed on the latter. This is achieved by providing in-depth studies on a number of major topics such as solder joints in conventional and advanced packaging components, commonly used lead-free materials, soldering processes, advanced specialty flux designs, characterization of lead-free solder joints, reliability testing and data analyses, design for reliability, and failure analyses for lead-free solder joints. Uniquely, the content not only addresses electronic manufacturing services (EMS) on the second-level interconnects, but also packaging assembly on the first-level interconnects and the semiconductor back-end on the 3D IC integration interconnects. Thus, the book offers an indispensable resource for the complete food chain of electronics products.

This book provides engineers and scientists with a single source introduction to the concepts, models, and case studies for making credible reliability assessments. It satisfies the need for thorough discussions of several fundamental subjects. Section I contains a comprehensive overview of assessing and assuring reliability that is followed by discussions of: • Concept of randomness and its relationship to chaos • Uses and limitations of the binomial and Poisson distributions • Relationship of the chi-square method and Poisson curves • Derivations and applications of the exponential, Weibull, and lognormal models • Examination of the human mortality bathtub curve as a template for components Section II introduces the case study modeling of failure data and is followed by analyses of: • 5 sets of ideal Weibull, lognormal, and normal failure data • 83 sets of actual (real) failure data The intent of the modeling was to find the best descriptions of the failures using statistical life models, principally the Weibull, lognormal, and normal models, for characterizing the failure probability distributions of the times-, cycles-, and miles-to-failure during laboratory or field testing. The statistical model providing the preferred characterization was determined empirically by choosing the two-parameter model that gave the best straight-line fit in the failure probability plots using a combination of visual inspection and three statistical goodness-of-fit (GoF) tests. This book offers practical insight in dealing with single item reliability and illustrates the use of reliability methods to solve industry problems.
