During the use of electronic products, many devices experience problems such as severe overheating, sluggish operation, and even motherboard burnout. Upon disassembly and inspection, it is often found that the thermal grease surface is dry and cracked—this detail directly reflects the close relationship between the condition of the thermal grease and the lifespan of electronic products. So, why does thermal grease crack during application? The core reasons are mainly threefold: uneven stirring before use, high low-molecular-weight content in raw materials, and excessive oil separation rate.
Before selecting and utilizing sealants on a large scale, rigorous performance testing is indispensable. Such testing serves to verify whether the product is compatible with the specific operating conditions, while also preventing post-application issues such as bonding failure, inadequate sealing, cracking, or detachment. Ultimately, this effectively minimizes material waste and reduces the risk of costly rework.
In LED heat dissipation, there is no absolute superiority of thermal pads or thermal grease; the choice depends on the application scenario. The two differ significantly in terms of usability, insulation, and lifespan. A detailed comparison is as follows:
Potting compounds are key materials in the adhesive and electrical manufacturing industries. They come in a wide variety and are highly targeted to specific applications. Only by selecting appropriate products can their protective and reinforcing functions be fully realized.
Potting compounds are used to encapsulate electronic components. This involves injecting a two-component liquid adhesive into the interior of a product containing electronic components and circuitry. After curing, it forms a thermosetting polymer insulating material, providing protection, insulation, and fixation. However, settling is a common problem with potting compounds during storage and use, and many users struggle to resolve it due to a lack of understanding of the causes. This article briefly analyzes the causes and impacts.
The application process of transparent potting compounds directly affects their final performance. The application procedure is basically the same as that of ordinary potting compounds. Strictly following the product instructions can effectively ensure bonding, sealing, and insulation effects.
