Thermal Conductive Silicone Usage Tutorial

Thermal conductive silicone is a commonly used material for heat dissipation in electronic devices. Proper use can effectively reduce the temperature of chips and radiators. This article will introduce the use and precautions of Thermal conductive silicone in detail.

What is Thermal conductive silicone

Thermal conductive silicone is a silicon-based material with high thermal conductivity, mainly used to fill the tiny gaps between electronic components and radiators to improve heat conduction efficiency.

Preparation before use

Cleaning the surface: Use anhydrous alcohol and lint-free cloth to thoroughly clean the contact surface between the chip and the heat sink, ensuring that there is no dust and oil stains

Preparing tools: Prepare tools such as Thermal conductive silicone, scrapers or plastic cards, gloves, etc.

Choose the right model: Choose silicone with a suitable thermal conductivity coefficient according to the heat generated by the device

Correct application method

Take out an appropriate amount of Thermal conductive silicone, usually a bean-sized amount is enough to cover an ordinary CPU

Use a scraper to evenly apply the silicone on the surface of the chip

The application thickness should be controlled at about 0.5mm. Too thick will affect the thermal conductivity

For larger chips, an "X" or "cross" shaped application method can be used

Install the radiator

Align the radiator to the chip position and slowly lower it

Gently press the radiator to evenly distribute the silicone

Tighten the radiator screws in a diagonal order to ensure uniform pressure

Precautions

Do not use excessively, as excess silicone may overflow and contaminate the circuit board

Avoid silicone from contacting the skin. If it accidentally contacts the skin, wash it immediately with soapy water

It is recommended to observe for 12 hours after the first use to confirm that the heat dissipation effect is stable

Generally, it needs to be replaced every 2-3 years, depending on the use environment

Through the above steps, you can correctly use Thermal conductive silicone to provide a good heat dissipation solution for electronic devices. Remember to check the heat dissipation effect regularly and replace the silicone in time when necessary to ensure long-term stable operation of the equipment.
