6:30pm Presentation

7:30pm Questions and Discussion


Microelectronic revolutions come in waves that are driven by necessity. Currently, the aging population is creating a need for various kinds of electronic systems to improve their quality of life. These include the restoration of lost functionality via electronic implants, better health screening technology and noninvasive monitoring in the home environment. In this talk I will present work that has been done towards addressing these needs, whether it be through the development of new required building blocks or through the development of more complex systems that combine custom built hardware and software. In particular the talk covers work done towards developing a vestibular implant for balance restoration, a single chip low-power imager for a bionic eye, a cancer screening capsule for detecting early-stage carcinomas in the small intestine and a bio-inspired acoustic scene analysis system.



Julius Georgiou (IEEE M’98-SM’08) is an Associate Professor at the University of Cyprus. He received his M.Eng degree in Electrical and Electronic Engineering and Ph.D. degree from Imperial College London in 1998 and 2003 respectively. For two years he worked as Head of Micropower Design in a technology start-up company, Toumaz Technology. In 2004 he joined the Johns Hopkins University as a Postdoctoral Fellow, before becoming a faculty member at the University of Cyprus from 2005 to date.


Prof. Georgiou is a member of the IEEE Circuits and Systems Society, is the Chair of the IEEE Biomedical and Life Science Circuits and Systems (BioCAS) Technical Committee, as well as a member of the IEEE Circuits and Systems Society Analog Signal Processing Technical Committee. He served as the General Chair of the 2010 IEEE Biomedical Circuits and Systems Conference and is the Action Chair of the EU COST Action ICT-1401 on “Memristors-Devices, Models, Circuits, Systems and Applications - MemoCIS”. Prof. Georgiou has been selected as an IEEE Circuits and Systems Society Distinguished Lecturer for 2016-2017. He is also is an Associate Editor of the IEEE Transactions on Biomedical Circuits and Systems and Associate Editor of the Frontiers in Neuromorphic Engineering Journal. He is a recipient of a best paper award at the IEEE ISCAS 2011 International Symposium and at the IEEE BioDevices 2008

Conference. In 2016 he received the 2015 ONE Award from the President of the Republic of Cyprus for his research accomplishments. His research interests include Low-power analog and digital ASICs, implantable biomedical devices, bioinspired electronic systems, electronics for  space, braincomputer-interfaces (BCIs), memristive devices, inertial and optical sensors and related systems.

Low-Temperature Solders

Date: Wednesday March 22, 2017

Time: 4:30PM-7:00PM

Venue: Axiom Electronics

Address: 19545 NW Von Neumann Drive, Beaverton, OR 97006


The transition to Pb-free solders in electronics began in the early 1990s as a follow-on to the elimination of Pb-bearing solders from potable water systems and food handling equipment (1986).  The objective was to develop a single alloy having solidus and liquidus temperatures that were equal to, or less than, the eutectic temperature of the 63Pb-37Pb solder.  Three alloy development efforts were undertaken by Sandia Laboratories either as standalone projects or as a participant in one of the following partnerships: (1) U.S. Army, Redstone Arsenal (Huntsville, AL); (2) AT&T Engineering Research Center (AT&T/ERC, Princeton, NJ), and (3) National Center for Manufacturing Sciences (NCMS, Ann Arbor, MI).   The soldering technology data, which were developed from these efforts, were in three general categories: (a) existing, very low melting temperature solders 52In-48Sn (In-Sn) and 97In-3Ag (In-Ag); (b) development of the Sn-Ag-Bi solder (largest effort); and (c) the creation of non-Pb alloy compositions that achieved melting temperatures equivalent to eutectic Sn-Pb solder.  The In-Sn and In-Ag solders continue to find niche applications in optoelectronics and sensor products.  A materials and modeling database was developed for these solders as a toolset for predicting solder joint reliability.  The most widely-studied alloy is the 91.84Sn-3.33Ag-4.83Bi solder having the solidus temperature of 212°C.  Materials data included solderability testing to support process development activities as well as intermetallic compound (IMC) growth behavior and Pb contamination data necessary for predicting solder joint reliability.  The temperature cycling of printed wiring assembly (PWA) test vehicles provided TMF test data while materials properties data supported the computational models for predicting TMF.  The discussion will wrap up with a brief analysis of the Pb-free solder composition having solidus temperature (Ts) equivalent to that of the eutectic Sn-Pb alloy: 66Sn-5.0Ag-10Bi-5.0Au-10In-4.0Cu alloy, Ts = 178°C.  This material exhibited good solderability on Cu with a contact angle of 34.2+0.7°.  The physical metallurgy principles will be discussed that were used to develop this and similar, Sn-based, very low melting temperature solders.

Paul T. Vianco received a Ph.D. degree in Materials Science from the University of Rochester (New York) in 1986. He joined Sandia National Laboratories, Albuquerque, New Mexico in 1987 where he is currently a distinguished member of the technical staff.  Paul has been involved in all aspects of packaging interconnection technology: materials, processing, and reliability. Paul is a fellow of the American Welding Society (AWS) and ASM, International. He is also the author of the Soldering Handbook – Third Edition (2000) and Guideline for Hand Soldering Practices (2016), both of which are published by the AWS.
