Accessory - Thermal Interface Material

Thermal Interface

Thermal interface materials fill in any gaps and imperfections in the heat sink base and heat source. This minimizes the interface thermal resistance. Alpha offers several thermal interface materials in various sizes. Material choice will depend on attachment method, contact area size, flatness, attachment pressure, and desired thermal performance.

1. Phase Change Material Specification

These materials begin to soften and flow at an elevated temperature, filling the microscopic imperfections between the heat sink and heat source, reducing the thermal interface resistance.
Note : Alpha handles other materials which are not listed below. For example, Parker/Chomerics T766 can be specified. Please contact us if you require a different material.

2. Gap Filler Material Specification

These materials are soft and compliant, allowing them to fill any large gaps between the heat sink and heat source. Gap fillers can also be used when a single heat sink is cooling multiple heat sources.
Note : Alpha handles other materials which are not listed below. For example, Laird Tflex HD90000, can be specified. Please contact us if you require a different material.

3. Thermal Grease Specification

Thermally conductive grease offers low thermal resistance, and is far less sensitive to mounting pressure than other thermal interface materials.

4. Thermal Performance and Comparison Data

There are many types of thermal interface materials available in the market. Although each vendor publishes its own product test data, the results depend on the test methods and environment. These factors can be very different from real world operating conditions, making it difficult to compare TIMs accurately. In light of this, we tested the performance of the TIMs we offer in our own thermal lab. These results offer a good reference for comparison purposes.
