  • Mitigating Tin Whisker Risks: Chapter 9 Mechanically induced tin whiskers

    Tadahiro Shibutani, Michael Osterman( Role: Contributor ,  Chapter 9 Mechanically induced tin whiskers)

    Wiley 

     More details

    Language:English Book type:Scholarly book

    This chapter discusses the pressure-induced whisker at separable interfaces as a key reliability issue of lead-free separable contacts and connectors. It shows theories of mechanically induced tin whiskers. Then, several case studies with pure tin and lead-free finishes were performed to evaluate pressure-induced tin whiskers. For electronics components, several factors affect the stress field of the finish: (i) thickness of the plating, (ii) structure of the ambient component material, and (iii) material microstructures. As a methodology for the assessment of pressure-induced tin whisker formation, the creep-based tin whisker formation model shows good results. Several connectors with tin or tin-rich alloy finishes were assessed by means of the nanoindentation technique. For the flexible printed circuit (FPC), mechanical properties of adhesives are key factors influencing tin whisker formation. Each mechanical property can be obtained by the indentation technique, and stress distribution can be estimated by finite element analysis (FEA).

    Prognostics and systems health management is an enabling discipline that uses sensors to assess the health of systems,diagnoses anomalous behavior,and predicts the remaining useful performance over the life of the asset. The advent of the Internet of Things enables PHM to be applied to all types of assets across all sectors, thereby creating a paradigm shift that is opening up significant new business opportunities. This paper introduces the concepts of PHM and discusses the opportunities provided by the IoT. Developments are illustrated with examples of innovations from manufacturing,consumer products, and infrastructure. From this review,a number of challenges that result from the rapid adoption of IoT-based PHM are identified. These include appropriate analytics,security,IoT platforms, sensor energy harvesting,IoT business models, and licensing approaches.

    <p>Improvement of condition-based monitoring for large bore 2-stroke marine engine cylinder liners and piston rings require close monitoring of anomaly wear elements in drain cylinder oil. This paper presents monitoring of seagoing ship engines because the environment of sailing affects the internal combustion conditions leading to mechanical failure of the cylinder liners. We presented condition-based monitoring of cylinder liners using X-ray to analyze drain cylinder oil samples. The approach for condition-based monitoring uses X-ray results to estimate wear amount and machine learning algorithm on elements in the drain cylinder oil samples. The wear amount is quantified for the purpose to estimate the degradation of cylinder liner materials through the drain cylinder oil samples, machine learning algorithm to evaluate the correlation of detected elements in drain oil samples. Finally, wear rate estimation to know the remaining useful life of the cylinder liner. Our results contributed to the improvement of condition-based monitoring of cylinder liners wear elements by quantification and machine learning to correlate elements in oil samples. Correlating wear elements facilitate quick decision-making on maintenance policies for slow-speed large bore 2-stroke engines.</p>

    本研究は、六自由度ランダム振動と温度環境槽を組み合わせた複合試験により、マイクロ接合構造の強度評価技術の高度化を目指す。限界に近い環境下で精密な機能が要求されるマイクロ接合構造は、高度な信頼性予測技術が求められる。耐熱樹脂-金属のマイクロ接合構造を対象に、まず、樹脂の粘弾性特性、硬化収縮、界面結合の不均一性を考慮した精密な接合強度信頼性評価モデルを構築する。続いて、六軸ランダム振動と熱負荷を同時に受ける複合試験を実施することで、界面の振動と熱により破壊する機構を解明し、実環境に近い六軸振動環境と熱変動環境でのマイクロ接合構造の信頼性評価技術の確立を目指す。
