Not necessarily. Thicker thermal pads can fill larger gaps, but they also increase thermal resistance, which actually reduces thermal conductivity. Compared to a 2mm thermal pad, a 1mm thermal pad has limited gap-filling capability but offers higher thermal transfer efficiency. You should choose based on a balance between the product’s clearance and heat dissipation requirements.
We do not recommend mixing 1mm thermal pads with other thermal interface materials. While thermal paste has better surface-filling capabilities than thermal pads, using it in combination with thermal pads may create air gaps. This can hinder heat transfer efficiency.
Graphite thermal pads are less effective at filling gaps than 1mm thermal pads. Furthermore, while graphite thermal pads offer better thermal diffusion, their thermal conductivity in the vertical direction is lower than that of 1mm thermal pads. You can also use them together to achieve more efficient heat dissipation.
It depends on your application. First, thermal grease can achieve a thinner thickness of less than 1 mm, making it good for smaller gaps between components and heat sinks. Second, a 1-mm thermal pad is a sheet with uniform thickness. Compared to fluid thermal grease, it does not fill complex surfaces as effectively. However, a 1-mm thermal pad provides a neater finish.
No. A 1mm thermal pad will compress and deform after installation. Reusing it may result in insufficient thermal contact area, which can compromise heat dissipation performance and reduce its service life. If you choose a 1mm thermal pad with an adhesive layer, the adhesive will lose its effectiveness after use and may even tear, making it unsuitable for reuse.
The lifespan of a thermal pad does not depend on its thickness. Its rate of degradation is influenced by factors such as operating temperature, thermal load, and installation conditions. Therefore, a 1mm-thick thermal pad does not necessarily degrade faster than a thicker one.
1mm and 0.5mm thermal pads have different thicknesses. The 1mm thermal pad can be used for larger gaps and is better at filling uneven surfaces. The 0.5mm thermal pad is suitable for the tiny gaps found in compact components, but offers higher thermal efficiency. It is a wise choice for portable devices and thin components.
What is the 1mm Thermal Pad?
1mm thermal pads are pre-formed sheets made from silicone or non-silicone materials with added thermal fillers. They have a fixed thickness of 1mm and offer excellent gap-filling and heat transfer capabilities. Thanks to their moderate thickness, they combine compressibility with thermal conductivity.
You can install them between electronic components such as CPUs, GPUs, and heat sinks. They quickly transfer heat generated by the working components to the cooling equipment, achieving cooling and the stable operation of the device.
How 1mm Thermal Pads Improve Heat Dissipation？
- Filling Gaps: With a thickness of 1 mm, this thermal pad offers good structural support while maintaining excellent flexibility and compressibility. It effectively fills gaps, replacing air, which has extremely low thermal conductivity. This reduces the resistance to heat transfer caused by air, allowing heat to transfer more quickly to the heat sink and improving cooling efficiency.
- Establishing a Thermal Pathway: After installation, a 1mm thermal pad is less prone to shifting or being pushed out than thinner pads, achieving stable contact. It maximizes the thermal contact area, creating a more efficient heat transfer path from the heat-generating component to the heat sink. This accelerates heat transfer and reduces localized hot spots.
How to Choose the Right 1mm Thermal Pad for Your Application？
Because the thickness of a 1mm thermal pad is fixed, you must measure the gap between the component and the heat sink to make sure that the 1mm thermal pad has a good seal after compression.
A thermal pad that is too thick will result in higher thermal resistance and take up more space. A thermal pad that is too thin will not provide the best thermal contact area. If the thickness is not suitable, you must replace it with a thermal pad of a different thickness to achieve better heat dissipation.
Determining the Thermal Conductivity
The thermal conductivity of a 1mm thermal pad determines its ability to quickly dissipate the heat generated by your product during operation. Thermal pads with higher thermal conductivity can be used in higher-power applications, but they also come at a higher cost.
Therefore, you should select a thermal pad based on your product’s maximum heat dissipation requirements during operation and allow for some margin. We offer thermal simulation testing to help you get accurate values and provide selection guidance, which can improve the efficiency of your selection process.
Selecting the material for a 1mm thermal pad
1mm thermal conductive tape is primarily available in two types: silicone-based thermal conductive tape and non-silicone thermal conductive tape. They have the same thickness but are made from different materials.
- 1mm Silicone Thermal Pads: 1mm silicone thermal padsare made from silicone rubber mixed with thermal fillers. They offer a wider range of thermal conductivity options and are highly compressible, so they can be used for heat dissipation in most consumer and industrial electronics. Additionally, they have a longer service life and are highly cost-effective.
- 1mm silicone-free thermal pads：1mm silicone-free thermal pads are made from silicone-free materials such as acrylic and polyurethane. Although it is more expensive and has poor long-term stability, silicone-free thermal padsdo not cause silicone contamination on components, providing greater safety for silicone-sensitive products. You can use it in projects such as optical modules, automotive electronics, and medical devices
Choosing based on Operating Temperature
The best working temperature of 1mm thermal pads is different by model, and the temperature affects their service life. You must select a model suitable for your application temperature to prevent the 1mm thermal pad from aging, hardening, and thermal conductivity decline during thermal cycling.
Most 1mm thermal pads are good for use between -50°C and 200°C; however, we also offer models with higher heat resistance for harsher environments. For example, carbon fibre thermal pads can operate normally between 150°C and 250°C.
Other Requirements
- Hardness: The hardness of a 1mm thermal pad affects how well it adheres to surfaces. Softer 1mm thermal pads are more compressible, allowing for better filling. While harder 1mm thermal pads are not suitable for uneven surfaces, they are less prone to sagging over time and have a longer life.
- Electrical Insulation: Most 1mm thermal pads, especially silicone thermal pads, are insulating and can prevent short circuits. You can choose pads with the right breakdown voltage to get higher safety. We also offer conductive thermal pads for special applications.
