Editor’s Note: This is the 2nd of a two-part summary from SEMI-THERM 33. Click here for Part 1.
SEMI-THERM 33 concluded last week at Silicon Valley, CA and Electronics Cooling was the only media and content provider present on the exhibit floor. We take this opportunity to thank our readers and contributors who stopped by our booth to learn about our plans for this year including 2017 Thermal Live! We are so pleased to know that many of you like our content, our new webpage, and our emphasis on covering thermal management across multiple disciplines.
SEMI-THERM this year featured many interesting companies showcasing their latest in thermal management solutions –to that extent that I barely managed to attend a couple of technical sessions! Most of my time was spent talking to the solutions providers of thermal management on the exhibit floor. Some of the highlights in the latest product and technology offerings include:
- Continued improvements in Thermal Interface Materials (TIM) –in thermal conductivity, thinner gap-filling and conforming materials.
- Test equipment for characterization of TIMs.
- Excellent advances in higher thermal conductivity materials for enclosures, carriers, substrates and heatsinks –Aluminum with Graphite, Chemical Vapor Deposited (CVD) Diamond, Carbon composites, etc.
- More improvements in user-friendly and better EDA-integrated thermal simulation tools.
- Continued advances in heatsinks –in form factor, materials, fabrication methods and integrated cooling fans.
- Advances in liquid cooling including thermal siphon, better quality and lightweight couplings, no-leak quick disconnects, etc.
For those of you who did not make it to SEMI-THERM this year, we requested all exhibitors to provide an update on their latest technology and product offerings showcased at SEMI-THERM. In the following paragraphs, you will find brief descriptions of the latest products from thermal management solution providers.
CEJN Industrial Corporation showed its latest products in quick connect/disconnect coupling for liquid cooling. Fluid products must be leak free, able to quickly connect and disconnect, able to withstand the transferred media and to endure the operating conditions to which they are subjected. CEJN’s Fluid products encompass all of these necessities. CEJN’s fluid couplers and nipples are available in valved and valve-less designs for low- and medium- pressure applications. Presented at SEMI-THERM are fluid couplings and nipples, hoses and hose kits for fluid applications.
Future Facilities highlighted the eleventh iteration of its leading thermal simulation software, 6SigmaET software for thermal management of electronics. The new edition includes an updated user interface designed for greater speed and accessibility, as well as an increase in the maximum resolution – allowing users to solve models up to 700 million grid cells. In addition to improved gridding capabilities, 6SigmaET has also announced a new Double Precision Solver function, designed to improve the calculation of the temperature residual to solve models in significantly fewer iterations.
The renewed focus on speed and solve time comes following independent research from Thales Global Services, which highlighted that 6SigmaET’s meshing time is up to 41x faster than its nearest competitor, with model convergence being reached 2.7x faster in an equivalent design. 6sigmaET has also improved its integration with the Rescale cloud platform. Within Release 11, users can now send models to Rescale for solving, monitor progress and retrieve results directly from the 6SigmaET user interface. They can also now use a client PC to submit and retrieve 6SigmaET jobs from a CFD server on a high-performance-computing cluster in the cloud.
Analysis Tech exhibited its complete product line of semiconductor thermal test equipment for performing device thermal characterizations, transient thermal analysis, and production die-attach and surge testing on any type of semiconductor device. The newly introduced Power Cycler is capable of evaluating power semiconductor device reliability directly with long-term cyclic heating waveforms while continuously monitoring for device degradation.Such testing is quickly becoming essential for power control modules being used in electric cars to wind generators. For material conductivity testing, the Analysis Tech TIM Testers offer precise TIM property measurements, suitable for laboratory or factory workplaces, in a physically robust and easy to use tester. Analysis Tech also offers the CTE Tester for measurement of thermal expansion in electronic packaging materials.
Schunk Hoffmann Carbon Technology showcased two graphite-based solutions for the electronics cooling industry, namely Aluminium Graphite and Latent Heat Carbon, at SEMI-THERM 33. Aluminium Graphite combines the low coefficient of thermal expansion, low density, and ready machinability of graphite with the excellent thermal properties of aluminium to create an ideal thermal management material for high-reliability applications. Customized parts, such as base plates or heat spreaders are readily produced with different platings.
Latent Heat Carbon is a novel approach to latent heat storage units. By using expanded graphite as a preform, a self-encapsulating material with a vastly improved thermal conductivity and low density is produced that enables the rapid buffering of temperature peaks during transient operation. In addition, the patented “Expand to Shape”production process allows for complex, custom designs at attractive cost.

Chilldyne Inc showcased its direct-to-chip liquid cooling demonstration system. The Cool-Flo® system offers all the benefits of liquid cooling without reducing uptime and with no worries about leaks. The system utilizes hybrid air-and-liquid-cooled heat sinks and negative pressure to deliver a zero-downtime, leak-proof, low-cost solution. Attendees had the opportunity to participate in the “cut-the-line” product demonstration where they could completely sever a cooling line over an Intel dual xenon server blade without causing any damage to the blade. The system uses negative pressure on both supply and return, therefore if a leak occurs air flows into the system instead of coolant out. The No-Drip/Hot Swap connector which automatically evacuates coolant from a server when disconnected, was also on display. The Chilldyne system is optimized for ease of installation and operation so that all the rack and server level connections do not require a plumber. The system installs into most servers and racks with no modifications making the switch to modern liquid cooling an easy decision.
