In the manufacturing industry, thermal grease is relatively common. This material not only dissipates heat but also has insulating properties. It is a heat-dissipating and non-conductive material. Because this material has high requirements for the coating process and is mainly thin and light, what will happen if too much is applied? Is there any countermeasure?
Is it good to apply too much thermal grease?
When applying thermal grease, the thickness should not exceed 3mm as much as possible. If the thickness exceeds the requirement, heat energy will easily accumulate on the surface of the CPU during work and cannot be dissipated as soon as possible. If the application is too thin, the heat energy of the heating element cannot be transferred out, and there is no point in using it. When the electrical heating element is connected to the heat dissipation facility, it needs to be tightened with screws. If too much thermal grease is applied, the excess grease will overflow. The excess grease will not have much effect on the PCB board. If it flows around the exposed contact point, it is easy to conduct electricity.
What should I do if too much thermal grease is applied?
Thermal grease is a silicone grease material that has no stickiness after use. If the coating layer is thick, you can use a scraper to clean the silicone grease on the surface, and then re-apply a thin layer of thermal silicone grease on the CPU surface and the bottom of the radiator, which will not affect the use.
Where can thermal silicone grease be used?
Thermal silicone grease can be used in routers, automotive electronics, sensors, graphics cards, communication equipment, LEDs, integrated lamps, televisions, radiators, rice cookers, water heaters, battery cars, computers, induction cookers, power supplies, controllers and other fields. Some thermal silicone greases on the market are suitable for use in CPUs, and some are suitable for use in electrical appliances. It is safer to buy a product without restrictions on the field of use, such as TENSAN, which focuses on the research of thermal silicone grease and provides customized thermal silicone grease application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
Thermal silicone grease has a relatively long shelf life, generally 3 years, and is suitable for large-scale purchase and storage. As long as the storage environment is ventilated, dry, and avoids direct sunlight, it can be stored for a long time.
