Precision-Clad Composite Materials for Heat Spreaders in ...

The heat spreader transfers and distributes heat from the source to a heat sink through a thermal interface material, or in some cases directly to air. The Need for Heat Spreaders The primary reason for using heat spreaders is to move the heat away from the source and avoid over-heating the electronic components.

Choosing the Right Thermal Interface Material ...

The thermal interface layer between the chip and the heat spreader typically is designated as "TIM-1," and the TIM layer between the heat spreader and the heat sink is usually designated as "TIM-2.". Several material solutions exist that can perform the functions of a TIM-1 or a TIM-2 – adhesives, greases, gels, phase change materials ...

back of the die to the heat spreader. The TIM is often the limiting factor for heat dissipation, either because it does not conduct heat adequately, or because it fails to maintain intimate contact between the back side of the die and the heat spreader. A family of advanced thermal interface materials for high-power FCBGA packages is discussed.

Thermal Interface Materials For Electronics Cooling

KEY PROPERTIES OF THERMAL INTERFACE MATERIALS Thermally conductive materials are used to eliminate these interstitial air gaps from the interface by conforming to the rough and uneven mating surfaces. Because the TIM has a greater thermal conductivity than the air it replaces, the resistance across the joint decreases, and the component
