The problem of bubbles in silicone encapsulant products is a common phenomenon in products in this industry. To prevent the occurrence of bubbles, it is necessary to formulate an effective and controllable inspection standard method. Today, I will share with you how to check whether the bubbles are completely eliminated after the silicone potting sealant is completely cured.
Silicone sealant is a one-component adhesive, both the operation method and the curing method are relatively simple, the performance after curing is outstanding, and it is favored by all walks of life, but little is known about the performance, storage conditions and use methods of silicone sealants.
There are many types of silicone potting compounds, and they are divided into one-component and two-component. The construction of two-component silicone potting compounds is more troublesome. It needs to be formulated in strict accordance with the proportion before curing. Correct, it is easy to appear the phenomenon of no curing or incomplete curing during the curing stage.
Thermal silicone pad and thermal grease are both thermally conductive interface materials and are widely used in electronic products. So which thermal silicone sheet or thermal grease has a better heat dissipation effect? What are the advantages and disadvantages of each of them? How to choose thermal silicone pad and thermal grease?
Thermal grease is also called thermal grease and thermal paste. It is a thermally conductive silicone grease-like compound made of organic silicone as the main raw material, adding materials with excellent heat resistance and thermal conductivity. A type of material used to fill the gap between the CPU and the heat sink, also known as thermal interface material. Its function is to conduct the heat emitted by the CPU to the heat sink, keep the temperature of the CPU at a level that can work stably, prevent the CPU from being damaged due to poor heat dissipation, and prolong its service life.
Thermal grease is often used in electrical or electronic manufacturing, because the main performance after use is thermal conductivity, and the construction requirements are extremely strict. If the thickness required for construction is not met, it will not have any thermal conductivity. At this time, many users think that silicone sealant also has thermal conductivity. Can it replace thermal grease?
