PADS Paper: 10 Things to Know about Thermal Design

Reading time ( words)

As designs get smaller, power densities at all packaging levels increase dramatically. Removing heat is critical to the operation and long-term reliability of electronics, and component temperatures within specification are the universal criteria used to determine the acceptability of a design.

Cooling solutions directly add weight, volume, and cost to the product, without delivering any functional benefit. What they provide is reliability. Without cooling, most electronic products would fail in a matter of minutes. Leakage current, and thus leakage power, goes up with smaller die-level feature sizes.

Because leakage is temperature-dependent, thermal design is more important. How should engineers who develop products with complex and/or high-power electronics ensure the thermal performance of their products while meeting other design criteria?

To answer this question, this PADS paper will take a look at 10 things you should know about thermal design of electronic products. To download this paper, click here.

Entering—and Enjoying—the Industry

I was recently given the opportunity to write an article for our publication. Being somewhat new to this industry, I figured it would be a good idea to write an introduction on how I got into electronics—specifically the part most people my age don’t give thought to.

IEEE’s Romanian SIITME Show a Success

01/09/2018 | Joe Fjelstad, Verdant Electronics
The 23rd annual IEEE International Symposium for Design and Technology in Electronic Packaging (SIITME) was held in Constanta, Romania, in October 2017. It attracted more than 190 participants from Romania, and 13 other counties. While there might be some who question the suitability of Romania as a venue for such a conference, the country has a long technological history and has produced some top innovators and pioneers in aviation including Aurel Vlaicu, Traian Vuia, Henri Coanda, who prototyped an early jet aircraft in 1910.

Romania’s PCB Design Students Compete at TIE 2017

06/19/2017 | Gaudentiu Varzaru, Politehnica University of Bucharest
During the last week in April, the 26th Interconnection Techniques in Electronics (TIE) show was held at the Gheorghe Asachi Technical University in Iasi, Romaina, a wonderful hill town not unlike Rome. The event, a convention for the Romanian electronic packaging community, included a series of actions designed to draw smart young students to the electronics industry, which is clearly growing. Participants had only four hours to create this PCB design, which was generated by a team of professionals from Continental Automotive Romania Timisoara.
