Thermal Imaging Demo
Welcome to AMD’s virtual booth at UT Girl Day 2021! We are excited to have you here and hope you learn a lot during your UT Girl Day experience.
This article will cover thermal imaging of electrical components. When an electrical component is turned on, some of the energy from the electronics is converted into heat. You have probably noticed this if you have used a computer or a phone for a couple of hours. By using an image of the electronics that shows hot spots, engineers can see which electrical components are drawing too much power or are close to breaking.
Today, we will be exploring the heat signatures that can be found on a computer motherboard. A motherboard can be thought of as the control center for your computer. For desktop personal computers, or PCs, the motherboard houses hundreds of tiny electronic components – like resistors, capacitors, or integrated circuits (tiny circuits on your circuit, called ICs) – that all work together. Each IC and component can generate heat while you use the computer.
But how can you see heat? Can’t you only feel heat?
Heat can be seen using a specialized camera called a thermal camera. The one we will be using today is called an infrared thermal camera, meaning it utilizes wave energy in the infrared spectrum to see the heat.
When you look up at the sky, you probably see blue. That blue color is a specific wave energy that can be seen by your eyes. Infrared is like another color, except that no humans can see it. But, when things get hot, they release infrared wave energy. So, if we can make a camera that sees infrared, we can see heat and visualize temperatures!
So, let us put this into practice. Here is a computer underneath an infrared thermal camera in one of the AMD labs. We will be focusing on the motherboard of this system.
The motherboard is the big red board in the top left of the photo. Let’s turn the system on and see what we can find!
In these images, we can see a general IC on the board heating up as it performs its assigned function. Notice how the thermal camera can capture the temperature in metal circuit traces in and around the IC!
In this example, the Voltage Regulator Module, or VRM, of the computer is heating up. The VRM ensures that the central processing unit (the CPU, such as a Ryzen series chip) is receiving the required voltage to operate correctly. Because nothing in technology is 100% efficient, some of the power going through the VRM is converted straight to heat. Notice how we can only see slim rectangles in the thermal image. These components are half-covered up with a heatsink (the big angular metal structure in the second image). A heatsink is used to cool down the VRMs – in real-world applications the VRM gets very hot!
You may be wondering about how those colors get into the image. The camera processes the image to put a color overlay so that it is easier for us to interpret the image. In this map, the more intense the color, the hotter that area is. You can use the color bar on the right of the heatmap images to tell how hot an area is.
How can engineers use thermal images to help create better products?
If you have particularly sensitive electronics, too much heat in an area can cause a fire or melt components right off the board. This is both unsafe for the user and damaging to the device. Engineers can use thermal cameras to see where there is too much heat so that they can fix the problem before it becomes a safety issue. Engineers can fix the problem by redesigning the circuit, remanufacturing the components, or using a cooling system.
Engineers have devised clever ways to cool down components, such as using a metal block with heat pipes and fins. The pipes direct the heat away from the device and the fins dissipate the heat into the air. In the enthusiast PC building community, many members use water to cool their electronics using specialized metal blocks, pipes, and pumps. Hardcore enthusiasts who push computer chip operating speeds to their absolute limit – an activity called “extreme overclocking” – will even use liquid nitrogen (−320°F) to cool their computers!
In this article, we explored how electronic components dissipate heat and how engineers can used specialized thermal cameras to see heat. In this application, we used a camera that can detect and see the infrared energy that is naturally emitted from a heat source. By using thermal cameras, engineers can ensure safe operating temperatures for the components or detect if a circuit is unexpectedly overheating. If the heat is a problem, engineers can fix the issue by redesigning the circuit or even adding a cooling system to the circuit.
From the AMD labs, thanks for stopping by! We hope you enjoyed learning about thermal cameras and hope you have a great experience at UT Girl Day 2021!
Engineer Your Own Blinky Lights
I’m an engineer at AMD, and I create both complex and simple things. Some of the things I create are called “circuits”, which is what all electronics are made of. I use the same process for everything I create, and I want to show you how I used that process to create a circuit that has blinking lights.
The first thing I do when creating something new is come up with a goal. My goal for this project is to create a pair of blinking lights. I did an internet search for “blinking lights circuits”, and found one I thought I could build.
Once I had a design, I simulated it, to see how it will work before I build it. I first drew the logical representation of the circuit, called a schematic, in an online circuit simulator. This is the free simulator I used: https://www.falstad.com/circuit/ . You can see different premade circuits in the “Circuits” menu of the website. Here’s a video clip of me drawing the circuit:
Once I had drawn the circuit in the simulator, I ran the simulator and it showed me the 2 lights blinking, just like I wanted:
3. Materials I took a look at the materials I had and compared it to the materials I needed for the circuit. Fortunately, I had everything I needed, but if I didn't, I would make a list of what I needed and buy it.
4. Build Once I had the plan and the materials, I set out everything I needed, and built the circuit:
5. Debug Once the circuit was all put together, I tested it. The first time I turned it on, it didn't light up like I expected. I double-checked all my work and found I had put a light in backwards. I had put the light’s longer leg on the left when it should have been on the right.
6. Show results After putting the wire in the right place, the circuit worked! It met my goal of making blinking lights, and the lights blinked the same as in the simulation.

AMD Computing for COVID
Interviews with the AMD Team
At AMD, we work hard on new products, and we also work hard on improving our community. One big way we’ve done that this year is by donating computer hardware to researchers that are working on COVID-19 research. The hardware we donated can do a lot of math, really fast: it can do over 1,000,000,000,000,000 operations per second! This hardware has helped those researchers understand COVID-19 and create treatments even faster. We’re proud to help out both our community and people around the globe.
Our CEO, Dr. Lisa Su, made a video about this, where she talks about how we’re contributing to COVID-19 research efforts, and shows some pictures of the type of hardware we’re donating:
Thanks for coming to learn more about AMD! Our engineers want to introduce themselves and tell you more about how they become interested in STEM – some of them knew from when they were very young, and some learned more about engineering as they got older! There are many paths ahead of you to learn and grow and you explore your interests.
