On Friday, Oct. 14, Advanced Thermal Solutions, Inc. (ATS) welcomed Dr. Marc Hodes and a group of six mechanical engineering students from Tufts University to its Norwood, Mass. campus. The students learned about the company, its products, and took a tour of two of ATS’ four laboratories to see some of the testing equipment utilized by ATS engineers.

After a welcome from ATS founder, President and CEO Dr. Kaveh Azar, the students enjoyed a brief introduction from Marketing Director John O’Day about the company, its products, and the importance of thermal management in the design of today’s high-powered electronics.

The lab tours were led by Dr. Bahman Tavassoli, ATS Chief Technologist. First, he took the students into the Characterization Lab to demonstrate the BWT-104 open-loop wind tunnel and the CLWT-067 closed-loop wind tunnel. The students learned how ATS engineers use Candlestick sensors, thermocouples and the iQ-200 to measure air velocity, temperature, and pressure across a PCB using one system. There was also a thermVIEW Liquid Crystal Thermography unit set up, in which ATS engineers use infrared (IR) cameras to examine hot spots on a cold plate.

The Tufts students learned more than simply how the testing processes worked. They also learned why thermal management is an important consideration in the early stages of a design. Dr. Tavassoli and Dr. Hodes spoke of their professional experiences in the field of thermal engineering and where projects had gone wrong when thermal issues were not considered in the planning stages.

Dr. Azar also joined the students in the lab to show them the wicking material being used by ATS engineers in state-of-the-art vapor chamber designs.

After the Characterization Lab, the students were taken into the Electronics Lab and were given a demonstration of the Water Flow Visualization equipment. ATS engineers use the equipment to test how air will flow through a system.

The students asked numerous questions of Dr. Tavassoli to get a better idea of the important concepts of thermal engineering that were presented in the 90-minute visit to ATS. Now, the students will have the real-world applications that they saw at ATS in mind when learning the concepts of thermodynamics, thermal fluids, and more in their Tufts courses.

Liquid Crystal Thermography Q & A

In light of ATS’ new release of the ethermVIEW, a high resolution liquid crystal thermography system, we sat down with Dr. Tavassoli, Chief Technologist at ATS to ask a few questions about liquid crystal thermography. Below is the Q & A session on commons questions that are asked about liquid crystal thermography.

Q: What are Liquid Crystals? How do they work?

A: Liquid Crystals reflect incident light at the visible wave length based on the temperature of the surface to which they are applied.

Q: Does the chip or the board get destroyed as the result of the ink/Liquid Crystal (LC) application?

A: No, ink and LC can be washed off with de-ionized water

Q: Can you reuse the LC treated surface?

A: Yes, as long as the surface is kept in a clean environment.

Q: How often do I need to calibrate?

A: Typically every time the LC is applied to a new surface, which is a good measurement practice.

Q: Are Liquid Crystals harmful?

A: No, but we do not recommend consuming them!

Q: Can you use LC’s for board level measurement?

A: Yes, LC’s can be used for any surface that can be treated with LC’s and trackable lighting.

Q: Can you mix different Liquid Crystal compounds?

A: Yes, however, it will be difficult to determine the temperature because the same colors, reflecting a temperature, will appear repeatedly as the surface is heated.
