Popular science: The correct application method and skill of thermal conductivity silicone grease

Thermal conductivity silicone grease, as a key material for heat dissipation of electronic equipment, its correct application is very important to ensure the effect of heat dissipation. In the following, we will introduce the correct application method and skills of thermal silicone grease in detail to help you easily master this practical skill.

First, preliminary preparation
Clean the surface: First, use a high purity solvent (such as high purity isoamyl alcohol ) and lint-free cloth (such as camera lens cloth) to clean the surface of the CPU core and the bottom of the radiator to ensure no impurities such as dust and oil. Take care to avoid touching the core and radiator surface directly with your fingers to prevent fingerprints or stains.

Determine the application area: Determine the area on the heat sink that is in contact with the CPU. This is where the thermal silicone grease needs to be applied.

Second, smear method

1. Dot coating method:

Squeeze a pea-sized piece of thermally conductive silicone grease in the middle of the bottom area of the radiator. Use a clean tool (such as a toothpick) to gently push the silicone grease away to form several small dots, ensuring coverage of the main contact area of the CPU.

2. Line coating method:

Extruded a thin line of thermally conductive silicone grease in the bottom area of the radiator. Use the tool to spread the lines evenly, forming a thin layer of silicone grease that covers the entire CPU contact area.

3, four weeks of application method (novice do not use) :

Place your fingers in the plastic bag to avoid direct contact with the silicone grease. Press back and forth with your finger on the bottom area of the heatsink until the silicone grease is evenly distributed over the area the CPU touches. Be careful not to overapply to avoid bubbles or spills.

Third, post-processing

1. Remove excess silicone grease: Use a lint-free cloth to gently wipe the bottom of the radiator to remove excess thermal grease. Ensure that the silicone grease layer is thin and uniform to give full play to its thermal conductivity.

2. Install the radiator: After confirming that there is no foreign object on the surface of the radiator base and CPU core, gently place the radiator on the CPU. At this time, only light pressure, can not rotate or translate the radiator, so as not to destroy the uniformity of the silicone grease layer.

Fourth, Matters needing attention

1, avoid bubbles: in the process of painting and installation, pay attention to avoid bubbles. Bubbles can affect the thermal conductivity of thermal silicone grease.

2, appropriate application: do not apply too much thermal silicone grease, so as not to overflow to the surrounding circuit board, causing short circuit or affect the normal work of other components.

3, regular replacement: with the growth of use time, thermal silicone grease may gradually aging or failure. Regular inspection and replacement of thermal grease is recommended to ensure good heat dissipation.

By mastering the correct application methods and skills of the above thermal conductivity silicone grease, you can easily improve the heat dissipation performance of electronic equipment and ensure its stable operation. Hope this article helped you!
