Thermal interface material fills the small gaps and irregularities between the heat sink and heat source to minimize the interface thermal resistance. The following interface materials are typically available with our products. These materials can also be purchased separately.

Gap Filling Material

These materials have high thermal conductivity and are soft, allowing them to fill any large gaps between the heat sink and heat source.

Phase Change Material

These materials begin to soften and flow at a certain temperature, filling the microscopic irregularities between heat sink and heat source, reducing the thermal interface resistance.

Thermal Grease

Thermally conductive grease. Compared to other type of thermal interface materials, grease offers the highest performance.

Adhesive Tape

Thermally conductive adhesive tapes are widely used due to the ease of heat sink attachment. Performance can be good, although not as high as the performance of phase change material or grease.
Note : The shear strength and thermal performance of an adhesive tape is dependant on many factors, such as the flatness and cleanness of the contact surface. The application instructions from the manufacturer (pressure versus time and temperature), should be followed to ensure adhesion. Please refer to the specifications/instructions from each tape manufacturer.
