How should thermal grease be used

What are the correct ways to use thermal grease? Today, Xiaobian has made a summary of several points that need to be paid attention to the correct use of thermal conductivity grease for your reference.
　　There are many different names for thermal grease, such as: thermal silicon, thermal paste, thermal paste, etc., in fact, their true face is thermal grease, but the name is different. Thermal conductive silicone grease is a kind of thermal interface material with high thermal conductivity and low thermal resistance, which has multiple functions of lubricant and thermal conductivity. Its real function is to increase the better bonding between the heat source and the radiator.
　　Here we talk about the correct use of thermal grease:
　　First, the general processor has two kinds of boxed and bulk. Boxed processing surfaces are relatively clean, while bulk processors can have a lot of dust or stains attached to the surface. Therefore, we should clean up before installation, and it is appropriate to use a clean cotton cloth or cotton ball to wipe. Dry the processor after wiping it clean to ensure that the surface is dry.

Second, when applying thermal grease, first determine the size of the contact surface between the radiator base and the heating source, and then apply the thermal grease, the amount of applied should be less. Use the finger sleeve, and then apply the thermal grease in one direction to the area in contact with the heat source, which is to ensure that the thermal grease can fill the uneven heat dissipation area. The heat dissipation capacity of thermal grease is not as good as that of metal, and the purpose of using thermal grease is to ensure that the two rigid substances on the surface of the radiator base and heat source are difficult to ensure all contact, and in the place where the contact is not reached, it is supplemented by thermal grease to increase the contact area between them, and achieve better heat dissipation effect from the surface. If the thermal grease is coated too thick, when the heat of the heating source is transferred to the radiator through the thermal grease, it will be found that the heat dissipation effect is significantly weakened, because the coating is too thick, the thermal resistance is greater, so the thinner the thermal grease is coated, the more flat the contact area will be, the smaller the thermal resistance will be.
　　Third, when installing the radiator to press, can not rotate and move the radiator, otherwise it will lead to coated thermal grease between the radiator and the heat source uneven problem, there may be bubbles affect heat dissipation.
　　After reading the above Xiaobian summary of several key points that need to be paid attention to the correct use of thermal conductivity grease, compare your thermal conductivity grease is painted correctly? The key is to remember not to take too much when applying thermal grease, more is not good for heat dissipation, will affect the heat source and the heat sink between the fit degree and increase the thermal resistance.
