The meaning of compressibility relative to TIM

Q:The meaning of compressibility relative to TIM

A:Choosing the proper thickness of thermal interface materials is very important, especially silicone as the based material. The ideal compressibility is between 15~20%, and depend on the different hardness with various item.

The compressibility of thermal interface material:

The main propose of thermal interface material is to fill the uneven interface and air hole between two materials (Heat source and heat sink) then dissipating heat out efficiency. With better connection and filling is the key point to apply thermal interface material.
