How about the performance of thermally conductive silicone pads? What are you usually used for?

The ** of silicone thermal pad is about one or two yuan per piece, and the cheap one is a few cents. Silicone thermal pads for different application scenarios are also different. In terms of application scenarios, it is used in power supply, LCD PDP TV, LED lighting, automotive electronics, optoelectronics, notebook computers and other industries.

Thermally conductive silicone pad LA-DS has good thermal conductivity and gap filling performance, and its material itself has a certain degree of flexibility and double-sided self-adhesiveness, which is generally used to fill the air gap between other components of the PC board, heat sink, metal shell and base, and can well fit the thermal conductivity and heat dissipation purposes between the power device and the heat dissipation aluminum sheet or machine shell gap, and also plays the role of shock absorption, insulation, and sealing. Recommend a brand - Huayue Thermal Conduction.

A thermally conductive silicone pad is a thermally conductive medium used to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat dissipation device. In the industry, it can also be called thermally conductive silicone sheet, thermally conductive silicone pad, soft heat dissipation pad and so on.

As electronics continue to pack more powerful features into smaller components, rising temperatures can lead to slower device operation, device failures in the middle of operation, size space constraints, and many other performance issues. As a result, temperature control has become one of the most critical challenges in the design, i.e., how to effectively remove more heat generated by a larger unit of power in a tight architecture with less and less operating space.

From an engineering point of view, the flexible thermally conductive silicone sheet is designed to match the irregular surface of the material, using high-performance thermally conductive materials, eliminating air gaps, thereby improving the overall thermal conversion capacity and enabling the device to work at lower temperatures.

It is used in power supply, LCD PDP TV, LED lighting, automotive electronics, optoelectronics, notebook computers and other industries. Peers also use thermal grease to conduct heat.

The thermal conductivity of thermally conductive silica gel gasket is generally ,. Different types of thermal conductivity also differ. Thermally conductive silicone gaskets are divided into: high thermal conductivity silicone pads, ordinary thermally conductive silicone pads, strong viscous thermally conductive silicone pads, and strong and tough thermally conductive silicone pads.

Thermal conductivity: Under stable conditions, when the temperature difference between the two sides is 1 °C, the heat transferred in one hour is 1 square meter. Thermal conductivity is measured in watt meters (W mk); Factors such as thermal conductivity and material composition, density, moisture content, temperature, etc.

Amorphous structure, low-density material, low thermal conductivity.

The material has a low moisture content and temperature, and a low thermal conductivity. Materials with a lower thermal conductivity are often referred to as insulating materials, and materials with a thermal conductivity of watts m or less are called insulating materials.

Thermal conductivity.

Thermal conductivity refers to a material's ability to conduct heat directly, or thermal conductivity. Thermal conductivity is defined as the direct conduction of heat by a material per unit temperature difference per unit section and length per unit time. The unit of thermal conductivity is Watt-1 Kelvin-1.

Thermal conductivity, where is the cross-sectional area of the heat conductor, is the heat conducted per unit time, is the thickness of the heat conductor between two heat sources, is the temperature difference.

The thermal conductivity of the general-purpose thermally conductive silica gel gasket is, and the thermal conductivity of the high-thermal conductivity type thermally conductive silicone gasket is.

The thermal conductivity of thermally conductive silica gel sheets is not fixed, usually. The higher ones are, such as BN-FS800

It is usually used for interface heat dissipation, shock absorption and buffering of heating components.

Silicone gasket has outstanding high and low temperature resistance, and the operating temperature: -70 +260

The current insulated one is 1W 15W; Without considering insulation, up to 30W.

The thermal conductivity of the silicone sheet is about 1-4w mk, I found Mr. Liu to test it, and sent an email to contact him.

Thermally conductive silicone pads, also known as thermally conductive silicone pads and soft heat dissipation pads, have good insulation and thermal conductivity, and can be shockproof. It can well realize the heat transfer between the heating and heat dissipation parts, and its thickness makes it very widely used. It can be used as a very good thermal conductive material, mainly on the surface of some irregular parts.

When using thermally conductive silicone pads, they need to be taken into account when designing. At the same time, there are many factors to consider, such as thermal conductivity, mechanism, installation testing, and so on. First of all, the thermal conductivity scheme, the previous thermal conductivity scheme mostly uses some thermal conductive sheets, but in the current design, in addition to the thermal conductive sheets, there are also some thermally conductive components, or cancel the thermal conductive sheets.

Of course, these are not fixed, in the specific implementation process, should be based on the specific requirements, to choose the most cost-effective one.

If you choose the thermal conductive sheet scheme, you need to consider some other factors, such as some protrusions on the surface of the component, avoidance, etc. In the design process, it is necessary to balance the size relationship between the structure and the thermally conductive silica gel sheet. If you can, it's a good idea to make the thermally conductive silicone pad thin enough.

Single-sided glue is more convenient to use, more convenient to operate, more recommended to use, when using, you need to paste the side with glue on the thermal conductive component, if there are conditions, it is recommended to use a good compression ratio of thermal conductive silica gel sheet, because it can give a certain pressure.

When choosing a thermally conductive silica gel sheet, you also need to consider the size of the power consumption and the specific thermal conductivity function of the thermal conductor. If it is a general chip, they are very sensitive to temperature, that is to say, there is a large heat flux density, so they all need to do a thermal conductivity treatment, the most basic also need, if possible, it is best to choose a thermal conductive silica gel sheet with a relatively high thermal conductivity. The maximum temperature of the general chip shall not exceed 85 degrees Celsius during production, and if the surrounding environment is high, it shall generally not exceed 75 degrees.

In such a situation, the thermal conductive silica gel sheet with high conductivity and heat lifting coefficient will naturally be welcomed by the majority of users.

When using thermal conductive silicone sheets, you also need to pay attention to the size of the silica gel sheets, because their specifications are different, of course, the size of this needs to be determined according to the covering heat source, if the size of the selected thermal conductive silica gel sheet is too large, it will not have a good impact on thermal conductivity, and even have a bad effect.

There are many factors to consider in the use of thermally conductive silicone sheets, and you must make a selection according to your budget.

Comparison of the specific advantages and disadvantages of thermal conductive silica gel sheet and thermal grease: 1. Thermal conductivity effect: In the short term, the thermal conductivity effect of thermal grease is better than that of thermal conductive silica gel sheet, because the thermal resistance of thermal conductive silica gel sheet is large, and the thermal resistance of thermal grease is smaller; 2.

Construction: The construction of thermal grease is troublesome, it is difficult to apply evenly, and it is easy to stain the surrounding devices. The thermally conductive silicone sheet is cut according to the size because it has been believed in advance, and it only needs to be torn off to protect the slippery and blind barrier film, and it can be pasted on the pasting surface, which is simple and convenient; You can choose according to your own needs and hardware conditions.

1. First of all, let's talk about the thermally conductive silicone gasket.

Also known as a thermally conductive pad, it is a thermally conductive gap filler material that is soft and has excellent thermal conductivity. The material is a composite material with excellent thermal and insulating properties, and its main components are boron nitride and polymer silica gel with high thermal conductivity. It is mainly used in high-end communication network equipment, and has been shipped on a large scale in industrial-grade and military-grade products.

2. Let's take a look at the thermal grease.

Thermal grease is a high-performance thermal grease based on silicone resin, which has high wetting characteristics and can very well fill the irregular microstructure on the surface of the device to form a very low thermal resistance interface. The coating thickness is usually between .

Thermal grease. Thermally conductive silicone gasket.

Personally, I think that what is the difference between thermal grease and thermal conductive silicone gasket and its application field need to be analyzed for different products from thermal conductivity, product structure, product performance, safety requirements and other aspects, and the conclusion is completely different, so today I will explain in detail from the different considerations of thermal conductivity, product application, and cost of the two.

If we only look at the heat dissipation and thermal conductivity of the product, of course, thermal grease is better, because we all know that thermal grease is a paste-like liquid, and we only need to lightly coat a thin layer of thermal grease conductive layer, so the thermal resistance is very low. In addition, the wetting properties of the thermal grease can squeeze out the air well enough. Improve its own thermal conductivity.

On the contrary, it is more difficult to achieve this low thermal resistance effect of thermally conductive silica gel sheets. Generally speaking, the limit of the thermally conductive silicone sheet can only be in the thickness, but considering the mechanical properties of such a thin gasket, glass fiber support is often added to the thin product, which is bound to increase the thermal resistance, so from the perspective of heat dissipation and thermal conductivity of the product, the thermal grease is obviously better than the thermal conductive silicone gasket.

Thermal grease. It is a thermally conductive grease compound that is commonly used for heat transfer at the thermal interface between high-power electronic components and heat sinks. Thermal grease has good thermal conductivity, which can make the chip work at a safe and stable temperature, prevent the chip from being damaged due to poor heat dissipation, and play a role in prolonging the life.

Thermally conductive silicone gasket. It is prepared with silicone rubber as the matrix, auxiliary thermal conductive filler materials, flame retardants and other functional additives. It has good thermal conductivity and compression resilience, and is mainly used for interface heat dissipation, shock absorption and buffering of heating components.

In fact, thermal grease is commonly known as heat dissipation paste, and thermal grease is made of silicone as the main raw material, adding materials with excellent heat resistance and thermal conductivity.

The composite is used for thermal conductivity and heat dissipation of electronic components such as power amplifiers, transistors, tubes, and CPUs, so as to ensure the electrical performance of electronic instruments and meters.

To put it simply, the shape of thermal grease is paste, and it plays the role of a heat transfer medium for electronic components, which can improve its work efficiency. And thermally conductive silicone pads.

They are often used in laptops or other electronic devices as a contact medium for heat sinks and packages, and their effect is to reduce the contact thermal resistance and enhance it.
