7.2.2. Gap Pad TIM Thermal Conductivity Data

The following table provides data on some common types of commercially available thermal interface materials tested using ASTM D5470 standards. These conductivity values consider contact resistance between heat source and heat sink by measuring the temperature drop across the TIM and calculating it based on the provided heat input, thereby delivering an effective thermal conductivity value.
