Thermal interface material (TIM) is used to enhance heat flow by reducing thermal resistance across the thermal interface between the heat source and the heat sink, and to minimize the variance of the interface resistance as compared to just surface-tosurface contact. In this mini review, the recent developments in the thermal properties of various used and advanced thermal interface materials ...

Contact behavior of thermal flying height control sliders and interfacial temperature rise upon head disk contact is investigated utilizing the resistance change of the read and write element. To achieve contact, the heater element of a TFC slider is energized with constant and square wave input profiles. To estimate the temperature rise during head disk contact, the resistance change of the re...

An approximate analytical model is developed for predicting the thermal contact resistance of spherical rough solids with the presence of interstitial gases. The joint resistance includes four thermal resistances, i.e., macrogap, microgap, macrocontact, and microcontacts. Simple relationships are derived for each component of the joint resistance assuming contacting surfaces are of uniform temp...

Greenwood’s approximation for the thermal resistance of a cluster of microcontacts is used recursively to estimate the thermal resistance due to a fractal array of circular contact areas motivated by Archa...
