TIM1, TIM1.5, TIM2

Indium Corporation has products for TIM1, TIM1.5, and TIM2 applications.

Solder preforms can be used between a processor die and a heat-spreader as a solder thermal interface material. This application is often referred to as TIM1 or first level TIM.

Heat-Springs^® and liquid metal can be used between a heat-spreader and a heat-sink as a compressible interface material. This is often referred to as TIM2, or second level TIM.

In mobile applications or bare die applications, such as laptops or video graphics boards, there is no heat-spreader, and the die is in direct contact with a cooling solution. This is referred to as TIM1.5. In this application, compressible materials, such as Heat-Springs^® or liquid metal, are used.
