thermal interface pad SIl-Pad A2000
At NEDC, we die-cut a lot of thermal interface materials (TIMs). Cost is always a concern when customers are selecting thermal pads. When selecting an .015’’-.020’’ thin thermal pad, Sil-Pad A2000 is a good choice.
Why Select Thermal Interface Pad Sil-Pad A2000?
I’m going give a few reasons:
-It comes in two thickness options that is between a “Gap Pad” and a “Sil-Pad” -.015’’ and .020’’
-It has great thermal performance
-It comes in rolls, unlike its counterpart Sil-Pad 2000- allowing for larger thermal preforms, and overall more affordable cost structure
-It has nearly all the same properties as Sil-Pad 2000, silicone base, fiberglass carrier, good UL rating, etc.
Sil-Pad 2000 vs Sil-Pad A2000? Are they the same?
I was going to write a blog on this, but I thought it would be better to have a note in here. I have the same exact note in my Sil-Pad 2000 blog. A lot of times customers confuse Sil-Pad 2000 with Sil-Pad A2000. They are different materials. One may ask, what are the differences?
-The Outgassing with Sil-Pad A2000 on the TML(Total Mass Loss) is slightly higher
-Sil-Pad A2000 is available only .015” and .020”, while Sil-Pad 2000 is available slightly thinner at .010”.
-Thermal Conductivity is better with Sil-Pad 2000, but only slightly.. Honestly, I might discount that a little bit more because thermal conductivity is an indicator – not necessarily a performance metric that can be depended on.
-Dielectric Constant is slightly better for Sil-Pad A2000
-The thermal performance and thermal impedance are essentially neck, and neck with Sil-Pad 2000 being slightly better.
Well its always a good idea to test in the application, Sil-Pad A2000 can be considered a good alternative to Sil-Pad 2000 for thermal applications.

More Information/Cutting
NEDC die-cuts, and waterjet cuts thermal pads for customers. For more information on thermal interface pads, or you think your application could utilize a thermal pad like Sil Pad TSP A3000. Sil Pad A2000 can be provided with an adhesive backing to aid in assembly.
