AOS Thermal Compound’s Micro-Faze® 3 A-4 is a non-silicone thermal pad that exhibits extremely low thermal resistance. It was designed to replace phase change materials and even high performance thermal grease. The pad is composed of 1 mil films of high thermal conductivity, tacky, but dry-to-the-touch thermal grease on either side of a 2 mil aluminum foil substrate. The material does not require heat to form into place; it will perform even with low mounting pressure. It can be die-cut to any size and is highly resistant to degradation and pump-out.
