Micralyne Scientist Wins Award for AuSn Solder Research
September 09, 2003
Edmonton, Alberta, September 9, 2003 – Micralyne Inc., a growing and profitable MEMS (Micro-Electro-Mechanical-Systems) company, announced today that Project Scientist, Dr. Siamak Akhlaghi, has received a Gold Medal Award from the American Electroplaters and Surface Finishers Society (AESF). Dr. Akhlaghi was presented the Abner Brenner Award for the best paper published in the Plating and Surface Finishing Journal during the year 2002.
The general topic of Dr. Akhlaghi’s paper is the electroplating of gold-tin eutectic solders, which are used for packaging microelectronic and optoelectronic devices because of their excellent thermal and mechanical properties and relatively low melting or reflow temperature. This type of electroplating is a cost effective alternative to current commercial solder deposition processes, such as evaporation and more flexible in terms of placement compared to solder preforms.
The award winning paper, Pulse Plating of Gold-Tin Alloys for Microelectronic and Optoelectronic Applications, focuses specifically on a co-electroplating process that has been developed for depositing Au/Sn alloys, from a slightly acidic, chloride-based solution using pulsed currents, onto patterned or blanket metallized ceramic and semiconductor substrates.
The study presents two separate AuSn compositions, Au-10Sn and Au-35Sn (wt%), that can be deposited under appropriate plating conditions. These compositions, according to the Au-Sn phase diagram, correspond to Au5Sn and AuSn, respectively. By using multiple current pulses and varying their duration, it is possible to deposit a composite solder structure with an overall composition ranging from Au-10Sn to Au-35Sn (wt%), including the important eutectic composition, Au-20Sn (wt%).
Along with this prestigious award, Dr. Akhlaghi’s work in the area of AuSn plating is also generating significant interest from many customers.
Micralyne develops and manufactures microfabricated and MEMS (Micro-Electro-Mechanical-Systems)-based products. Micralyne is one of the largest independent companies in the world that manufactures MEMS in high volumes. MEMS technology is built on the premise of making industrial components smaller, faster and less expensive and facilitates radical improvements in the miniaturization of electronic and mechanical devices. These types of devices are used in many industries including communications, automotive, aerospace, and life sciences. More specifically, Micralyne’s micron-scale solutions (i.e. 1000 microns = 1 millimetre) are found in automotive emission sensors, optical switching technology in telecommunication networks, lab-on-a-chip devices for drug discovery, and commercial press equipment for printing today’s most popular magazines. Micralyne is a profitable and growing company headquartered in Edmonton, Alberta, Canada.
