December 2020

Professor Avram Bar-Cohen, past President of IEEE Electronics Packaging Society, and past Editor-in-Chief of the IEEE Transactions on Components and Packaging Technologies passed away on October 10, 2020. He was a giant in the field of thermal management, and made seminal research and professional contributions over a five decade period. Professor Bar-Cohen’s research focused on several areas in microsystems packaging. His work on air cooling focused on optimization of natural and forced air cooling devices, and sustainability and life cycle considerations of thermal management devices. His work spanned the spectrum from fundamental research to emerging applications, including 2.5D and 3D heterogeneous integration, radio frequency, opto-electronics, and power electronics devices and systems.

Title: The Evolution of Lead-free Solder Alloys

Date: December 16, 2020

Presenter: Dr. HongWen Zhang

Dr. HongWen Zhang is the Manager of the Alloy Group at the Indium Corporation's Research & Development Department. His focus is on the development of lead-free solder materials and the associated technologies for high temperature and high-reliability applications. He and Dr. Ning-Cheng Lee invented the mixed powder technique to combine the merits of constituents to improve wetting, reduce processing temperatures, modify the bonding interface, and control the joint's morphology, thus improving the reliability.

Introduction

“Real 3D” integration - 3DIC Integration in its true definition - has a long history. As early as 1985, Richard P. Feynman expressed this vision: “Another direction of improvement of computing power is to make physical machines three dimensional instead of all on a surface of a chip. That can be done in stages instead of all at once - you can have several layers and then add many more layers as time goes on”.

Greeting from Chapter Chair:

Greetings to all EPS M’sia members. Time flies, we are approaching the end of Y2020, with many new methods of living and working; basically establishing new norms in this pandemic Y2020. This newsletter also marks our planning on the forthcoming new year!

While World Health Organization (WHO) and all our government agencies reminding us on the important of avoiding the 3Cs (crowded places, close contacts and confined spaces), the semiconductor leaders feel that COVID-19 will have a positive impact on the investment and growth in the industry that all of us are working on. This great opportunity lies ahead of us with more adoption of 5G, greater usage of artificial intelligence, and Internet of Things (IoT) as it will result in increased investment in the state-of-the-art technology computing power to enable the industry 4.0 Initiative. This indeed a very good sign for all of us to continue to have engineers capable of handling this development while learning to adapt further to these new norms of life challenges.
