Silver-Indium and Its High Temperature Electronic Applications ๐Ÿ—“

The silver-indium (Ag-In) binary system is reviewed. This system has never been used in electronic industries except In-3%Ag eutectic for bonding laser diode chips. It was chosen for our packaging process development because of its forward looking possibilities that other systems do not possess. Next, conventional die-attach materials and fluxing action in soldering processes is briefly presented. Several processes dealing with tin oxides are mentioned. Our fluxless bonding is then introduced. Four fluxless bonding designs using the Ag-In system are reported. The joints were made at 250 degrees C. All joints produced have melting temperature higher than 700ยฐC. Samples of the third design survived 5,000 thermal cycles between -40 to +200ยฐC. The fourth design survived storage at 350ยฐC for 200 hours.

The joints reported above contain pure Ag, solid solution (Ag), and/or Ag2In intermetallic compound. To find out the mechanical properties of these materials, ingots have been grown in house. ASTM tensile test (TT) samples are prepared. (Ag)-19In TT samples exhibit superior tensile properties compared to pure Ag. Here (Ag)-19In means solid solution with 19 at. % In. The hardness and fracture toughness of Ag2In are measured. Reaction experiments with sulfur (S) vapor shows that the reaction rate with (Ag)-19In is much lower than that with pure Ag and the commercial available Agentium Ag. It seems that (Ag)-19In has the superior anti-tarnishing property that the metallurgy community has been looking for several centuries.

Ag has superior physical properties. The challenge in its electronics, jewelry, and optical applications is tarnishing. It reacts easily with S and H2S to form Ag2S which is black and fragile. Our preliminary results on the properties of (Ag)-xxIn seem to indicate that (Ag) solid solution might be an answer.

Error correction codes (ECC) are ubiquitously used in data storage to provide fault tolerance. Traditionally, redundancy and error tolerance capability are considered the key performance measures for ECC. In distributed storage, however, codes need to be developed for the new challenges brought by the networked nature of the system. In this talk, we present regenerating codes, a family of codes that are efficient for failure correction. For systems with 2 redundant storage devices, the repair bandwidth can be reduced by 1/2 compared to traditional ECC.

Dr. Zhiying Wang is an Assistant Professor at University of California, Irvine. She was a postdoctoral research fellow at Stanford University. She received Ph.D. and M.S. in Electrical Engineering at California Institute of Technology, and B.S. in Information and Electronic Engineering at Tsinghua University. Her research interests include information theory, coding for data storage, and compression for genomic information. She is the recipient of IEEE data storage best paper award and NSF Center for Science of Information Postdoctoral Fellowship

Event Details & Registration:
Summary: High-speed chargers for electric vehicles (EVs) are growing in public locations. They are the fastest growing segment of chargers. With the release of more than 20 new EVs at the Detroit Auto Show in January 2017, the demand for public charging is going to grow. EVs finally cover most of the vehicle segments from motorcycles to semi-trucks. In many cases a single high-speed charger can exceed the installed electric service in a small parking garage or highway rest area.
— Looking at real data from public chargers, what are the impacts?
— Does the typical solar cycle support the typical charger usage profile?
— What are the other lessons learned.
— Presentation is based on real world data.

Summary: A well-known story is predicting performance of Boston Red Sox players enabling them to win 3 World Series since 2004. The movie, โ€œMoneyballโ€ also touched on PA. We focus on team ratings/rankings and predicting winners. We explore creating ratings from pair-wise comparisons and sort them to get rankings and discuss underlying mathematics. Pythagorean theorem and the Log 5 formula are used to compute wins. We use the Elo Rating System to rank players and teams. Finally, โ€œaggregation of rankingโ€ is done as an input to our prediction model. We use the Borda method for rank aggregation. We explore various PA models for sport. Regression models with several predictor variables estimate win probability. Start with polynomial regression and analyze over-fit. These are the foundation for Ridge and Lasso Regression, used heavily in Sports prediction. Sentiment measurement and Social Media data mining can be input also. PA works best when the data is accurate and properly sampled. There are also fee-based data sources. We analyze accuracy of various models and explore prediction algorithms improvement.
