| Thermally conductive gel is a new and expensive thermal interface material that has emerged in recent years, and thermally conductive silicone grease is the veteran of the thermal interface material family. Both materials are in paste form, and many customers have not been able to distinguish between thermally conductive gel and thermal conductivity. The difference between silicone grease, some people actually acquiesce that thermally conductive gel is thermally conductive silicone grease, just a different name. In this context, today's new editor of Jiadi will discuss the difference between thermal gel and thermal grease with everyone. The difference between thermal gel and thermal grease: the construction methods of thermal gel and thermal grease are different. Thermally conductive gel is a kind of ultra-high-viscosity thermal conductive material, which is made of a variety of thermally conductive powders and thermally conductive silica gel after being thoroughly matured and mixed. The entire production process is completed in a vacuum state, so there is no point in the thermal conductive gel material. Air and thermal gel are also packaged in syringes. During construction, the automatic dispensing machine can dispense the glue directly, which ends the history that the thermal interface materials cannot be automated. The thermal conductive silicone grease is different from the thermal gel in terms of the formula or the production process of the thermal conductive silicone grease. The packaging method that contains the thermal conductive silicone grease is also simple canned. The construction method is usually screen printing, and some customers use more To make it quicker, just change it and scrape it evenly. However, such a simple construction method requires manual operation. In short, the thermal gel can be applied with a fully automatic dispensing process, while thermal grease can only be applied manually. The second difference between thermal gel and thermal grease: the operating life of thermal gel and thermal grease is different. Thermally conductive gel is permanently non-drying and can be compressed indefinitely. It can guarantee a service life of more than 10 years with customers. Some manufacturers call thermally conductive gel a liquid thermally conductive silicone sheet. However, the life span of thermal conductive silicone grease is the shortest in all thermal interface materials. Since the thermal grease has been used for half a year, it will gradually become dry and powdery, and it can be completely turned into powder within two years at the longest. It will become dust when you pinch it, and the thermal grease will lose its thermal conductivity. The life span of thermal grease is over. This is also the most complained of thermal grease, and it is also a life-threatening bottleneck in the development of thermal grease. There are many differences between thermal gel and thermal grease, such as thermal resistance and thickness. Therefore, this kind of evidence indicates that thermal gel is not thermal grease, and both have their own uses. Customers can choose to use thermal gel or thermal grease or other thermal materials according to their product characteristics and product structure requirements. |
