Introduction to Carbon Fiber-Orientated Thermal Gap Filler

Thermal gap filler conductivity has increased dramatically over the last 10 years. The ever-increasing power and smaller area have driven the need for higher conductivity thermal gap fillers. In order to increase thermal conductivity, Fujipoly has explored various thermal fillers to achieve ultra-high thermal conductivity. One of those fillers is Carbon fiber.

In this whitepaper, we look at the need for higher conductivity materials and how carbon fiber-oriented thermal gap fillers can meet the demand for higher heat flux. Carbon fiber-oriented thermal gap fillers exhibit very low thermal resistance while still offering a highly compressible thermal gap filler. We explore some of the properties of carbon fiber-oriented gap fillers as well as best practices for implementing them. We explain how they can be a great option when more conventional thermal gap fillers are not proving the thermal resistance or compliance needed.
