thermal pad application, high powered, lab, good place for TFlex SF10
Thermal Pads are the future. I don’t think anyone can overstate that at this point. Electronics are getting smaller, while the power densities obviously increase. Recently, I discovered a material that we really liked. It had a lot of qualities that we often hear sought after when discussing thermal pads. What are these qualities?
Properties of TFlex SF10
-Silicone-Free
Silicone can be insidious in an application, especially in lighted/image applications due to the fogging that can happen from silicone bleed that is inherent in silicone products. TFlex SF10 is a silicone-free thermal pad.
-High Compliance under Low Pressure
A thermal pad can have a high thermal conductivity like a brick. However, what is ideal to see is a pad that does both high compliance under low pressure. Pressure is a luxury, but sometimes it isn’t as available as you may think.
-Large thickness availability of 0.020-0.200
When it comes to thermal pads, thickness of thermal pads usually tops out at .125’’. As everyone knows, think “Thin to Win” however, when it comes to thermal pads, sometimes just a thicker thermal interface pad is the way to go!
-Electrical Isolation
Electrical Isolation, and high thermal conductivity are usually not in the same category, but this pad without any fiberglass reinforcement, is a fantastic electrical isolation product.
-High Thermal Conductivity
What is High Thermal Conductivity? This pad has a 10 W/m-K. This is some of the highest you see when it comes to thermal pads.
Drawbacks:
Some understood drawbacks of SF10 include the fact there are no fiberglass reinforcement on the pads. I personally like fiberglass reinforcement because its makes it easier to handle pads without the pad falling apart well placing the pad into the application. Oftentimes, with high conductivity pads, stability can be a problem- because thats also what can make them great.
