Long-Term Reliability
Compared to thermal paste and thermal tape, adhesive thermal pads offer a longer lifespan of approximately 2 to 10 years. This allows them to achieve satisfactory performance over long use while needing lower maintenance. Their adhesive layer sustains bonding under vibration and compression for extended durations. Additionally, they withstand temperatures ranging from -50°C to 200°C and thermal cycling, so you can use them in harsh environments. Consequently, they provide long-term, reliable thermal management for your products.
Applications of Sticky Thermal Pad
Thermal pads can be used between LED modules and aluminum substrates or heat sinks to achieve stable brightness and extend service life.
In the power supply industry, adhesive thermal pads used in MOSFETs, transformers, and switching enhance heat dissipation efficiency while maintaining electrical insulation.
Sticky thermal pads withstand vibrations and impacts during vehicle operation, providing thermal management and cushioning for ECUs, BMS, LEDs, and charging modules.
Combine thermal conductivity with mechanical retention, making them suitable for multi-module integrated communication equipment, RF modules, and base station modules.
The use of electronic devices such as mobile phones, routers, and cameras can enhance assembly efficiency, meet mass production demands, and reduce BOM costs.
Sticky thermal pads are suitable for harsh industrial environments, offering long-term continuous operation and providing stable heat dissipation.
Naturally adhesive thermal pads remain unaffected. The adhesive layer lacks high thermal conductivity fillers, which may impact thermal conductivity. However, this effect is minimal, and you can select an appropriate thermal conductivity based on your heat dissipation requirements.
Thermal pads may deform and lose adhesion strength during use and removal, and are not suitable for reuse. Therefore, you’d better not reuse it.
Thermal conductive tape offers strong adhesion but typically has poor compressibility and low thermal conductivity. Adhesive thermal pads provide sufficient holding force while effectively filling gaps and enhancing heat dissipation.
Yes. Most adhesive thermal pads are insulating to enhance safety in electrical equipment and high-voltage applications. You can also customize conductive thermal pads for specialized applications.
Silicone and silicone-free adhesive thermal pads are manufactured using different materials. Silicone-free adhesive thermal pads contain no silicone material, do not release silicone oil or silicone gas during use, and will not damage silicone-sensitive components.
What is a Sticky Thermal Pad？
Sticky thermal pads are thermal interface materials with enhanced adhesive strength. They are typically self-sticky or laminated with an adhesive layer. This achieves superior adhesion to component and heat sink surfaces, minimizing contact thermal resistance and improving heat dissipation efficiency. Additionally, it enhances assembly stability, reduces risks such as displacement, and delivers superior long-term reliability. In certain low-temperature and stable applications, mechanical fastening may not be required. They are suitable for applications susceptible to vibration and shock, such as automotive electronics, communication equipment, and power supply modules.
Types of Sticky Thermal Pad
Silicone-Based Sticky Thermal Pad
Silicone-based sticky thermal pads are typically manufactured using silicone rubber blended with fillers such as aluminum oxide, boron nitride, and aluminum nitride. Owing to their exceptional elasticity, compressibility, and insulation properties, they find widespread application in industrial control equipment, communication devices, LEDs, and similar applications. Flexible and compressible, they effectively fill air gaps while offering good performance between -40°C and 200°C. However, being silicone-based materials, they may have silicone migration issues during prolonged use.
Non-Silicone Sticky Thermal Pad
To prevent contamination and damage to components caused by silicone oil and silicone gas emitted from silicone-based sticky thermal pads, non-silicone sticky thermal pads are specifically designed for silicone-sensitive products. Non-silicone sticky thermal pads use non-silicone polymers as their base material, incorporating thermally conductive fillers instead of silicone rubber. Being silicone-free and more stable, they do not contaminate components during use. So they are suitable for products with high hygiene standards or for precision electronic and optical equipment. However, they offer lower high-temperature resistance compared to silicone-based sticky thermal pads and come at a higher cost.
Natural Tacky Surface Thermal Pad
Natural tacky surface thermal pads have inherent tackiness, eliminating the need for additional bonding layers. Consequently, they require no extra thickness, making them ideal for thin-profile applications. Moreover, they achieve lower thermal resistance, resulting in superior heat dissipation efficiency. However, due to their weaker adhesive properties, natural tacky surface thermal pads are better suited for short-term projects or products with minimal bonding requirements.
Single-Side Sticky and Double-Side Sticky Thermal Pad
Thermal pads are often combined with pressure-sensitive adhesives to form sticky thermal pads with higher bonding strength. They primarily come in single-sided and double-sided varieties. Single-sided thermal pads feature an adhesive layer on one side and a standard thermal surface on the other, primarily used to reduce installation misalignment or in single-sided mounting applications. Double-sided thermal pads have adhesive layers on both sides, offering stronger fixation. You can use them in vertically structured products to achieve higher mechanical strength. However, they are difficult to disassemble and exhibit higher thermal resistance.
Sticky Thermal Pad vs Common Thermal Pad
Sticky Thermal Pad vs Common Thermal Pad: Function
Standard thermal pads primarily serve to conduct heat and lack adhesive properties. During installation, they require screws, clamps, or similar fasteners for secure mounting to enhance stability. In contrast, sticky thermal pads provide both thermal conductivity and a degree of fixation. This makes them more convenient for automated assembly, minimizes displacement, and reduces the risk of failure.
Sticky Thermal Pad vs Common Thermal Pad: Thermal Conductivity
Since the bonding layer does not mix thermal conductive materials, its thermal conductivity is relatively low. As a result, adhesive thermal pads with bonding layers typically have lower thermal conductivity than standard thermal pads. However, heat dissipation performance does not depend on thermal conductivity. Adhesive thermal pads offer superior adhesion, enabling lower thermal resistance. Furthermore, in high-vibration and shock-prone applications, they have less displacement, potentially achieving more efficient heat dissipation than standard thermal pads.
Sticky Thermal Pad vs Common Thermal Pad: Assembly Efficiency
Thanks to the superior adhesion of adhesive thermal pads, they adhere more easily to surfaces with less displacement. This eliminates the need for positioning, pressing, and alignment steps required by standard thermal pads, simplifying the process. Furthermore, they produce fewer defects and errors during assembly, reducing rework and getting better quality control. Therefore, whether for small-batch or mass production, adhesive thermal pads prove more efficient than standard thermal pads.
Sticky Thermal Pad vs Common Thermal Pad: Cost
Adhesive thermal pads need more complex manufacturing processes, typically more expensive than standard thermal pads. However, their simpler assembly reduces installation and labor expenses. They also have fewer assembly defects, preventing material waste from rework and further cutting costs. Additionally, in low-vibration and low-temperature applications, they don’t need additional mechanical fasteners. Therefore, overall, adhesive thermal pads may be more cost-effective.
Sticky Thermal Pad vs Common Thermal Pad: Application
If you seek higher assembly stability, adhesive thermal pads are the first choice. They can be used in applications involving vibration, shock, and vertical structures, and have less displacement during transportation and use. Moreover, you can use them in automated placement to get a higher efficiency. Standard thermal pads, however, are better for products with mechanical fastening and clamping. Due to their easier removal, they are ideal for products requiring frequent maintenance. Additionally, they have higher thermal conductivity, and you can use common thermal pad in high-power and demanding heat dissipation applications.
