Instructions of applying thermal phase change materials For heat sinks

In the field of modern electronic equipment in pursuit of effective heat dissipation, thermal phase change materials have become a key bridge connecting heat sinks and heat sources with superior thermal conductivity. How to operate the thermal phase change material on the heat sink? The following is a detailed how-to guide to accurately and efficiently apply thermal phase change materials to your heat sink.

Preparation

1, cleaning and inspection: use a dust-free cloth dipped in an appropriate amount of electronic cleaning agent, gently wipe the radiator and heat source surface, to ensure that no oil, dust and impurities remain. Then check whether the packaging of the thermal conductivity phase change material is intact to avoid contamination or damage to the material during transportation or storage.

2, environmental preparation: Ensure that the operating environment is clean and dust-free, to avoid the introduction of impurities in the operation process. Maintain appropriate temperature and humidity to avoid material performance due to environmental changes.

Laminating steps

1, material preparation: take out the thermal phase change material from the package, and carefully tear off the protective film on one side. Take care to keep the material flat and avoid curling or folding.

2, preliminary positioning: the thermal phase change material is gently placed on the radiator, according to the location of the heat source for preliminary positioning. Make sure the material covers the heat source area and the edges are aligned with the edges of the heat sink.

3, tight fit: Use a professional tool (such as a scraper or roller) to gently press the thermal phase change material to make it closely fit with the radiator surface. Pay attention to uniform strength, avoid local pressure too much to cause material damage. During the laminating process, the radiator can be moderately heated (such as using a hot air gun, but the temperature must be controlled not exceeding the material tolerance range) to promote the phase transition process of the material with thermal phase change and improve the laminating effect.

4, tear off the remaining protective film: after the thermal phase change material is fully fitted with the radiator, carefully tear off the other side of the protective film. Pay attention to avoid displacement or deformation of the material during the film tearing process.
