AOK Technologies, formally known as Shenzhen Aochuan Technology Co., Ltd., is a leading developer and manufacturer of thermal interface materials (TIMs) and related solutions, specializing in thermal management and electromagnetic interference (EMI) shielding for electronics. Established in 2004 and based in China, AOK has built a strong reputation for delivering innovative products that enhance the cooling and reliability of electronic devices across industries like automotive, data centers, drones, and electric vehicles (EVs). 

Thermal Management Innovations

Focuses on creating advanced TIMs that bridge the gap between heat-generating components (like CPUs, GPUs, and power electronics) and heat sinks or cooling systems. Our thermal solutions are designed to efficiently dissipate heat, ensuring electronics remain cool and perform reliably under demanding conditions. Key innovations include:

1. Diverse TIM Portfolio

Thermal Pads: Offers soft, thermally conductive gap fillers, such as the UTP100 series, which feature a fiberglass-reinforced liner for added durability. These pads are highly conformable, filling microscopic gaps to reduce thermal resistance and improve heat transfer. They’re ideal for applications with uneven surfaces or varying tolerances, like EV battery packs or automotive electronics.

Thermal Grease/Paste: These compounds eliminate air gaps between components and heat sinks, offering low thermal resistance (around ≤ 0.15 ~ 0.04°C-in2/W under pressure). They’re easy to apply and excel in high-power devices where precision cooling is critical.

Phase-Change Materials: Combining the benefits of adhesives and grease, these materials transition from solid to liquid at specific temperatures, providing excellent heat transfer without the "pump-out" issues of traditional grease. They’re suited for standard transistor assemblies and compact electronics.

Thermally Conductive Adhesives and Potting Encapsulants: These provide structural support alongside heat dissipation, protecting components while managing thermal loads in rugged environments like drones or industrial equipment.

2. High-Performance Materials for EVs and Data Centers

Tailors its TIMs for EV electronics, such as battery packs, powertrain systems, and power electronics, where heat dissipation is vital for safety and longevity. Their gap fillers and pads address the high heat flux of silicon carbide power modules and densely packed battery cells.

For data centers, Our solutions support high-performance servers and network equipment, ensuring operational stability as power densities rise with AI and 5G advancements.

3. Electrically Insulating Thermal Sheet

A unique innovation, this material integrates thermal conductive powders (e.g., boron nitride or aluminum oxide) into polysiloxane rubber with a glass fiber cloth carrier. It’s solid yet flexible, simplifying assembly while maintaining excellent thermal conductivity under pressure. This is particularly useful for standardized transistor cooling in compact designs.

4. Customized Solutions

Possesses the ISO9001, ISO14001, IATF16949 quality management system certifications, with all products going through UL, SGS, RoHS certification. Designs, develops and manufactures thermal interface materials for industry leaders around the globe. Committed to becoming the world's leading supplier of thermal materials and solutions. Our core capabilities allow AOK to provide customers with customized solutions to meet their specific application needs.

EMI Shielding Innovations

Our expertise extends to integrating EMI shielding into thermal solutions, especially for applications like drones and automotive electronics where electromagnetic compatibility (EMC) is critical:

1. Integrated Thermal-EMI Solutions

AOK TIMs can be paired with conductive coatings or shielding layers (e.g., copper or aluminum) to address both heat and EMI in a single application. For instance, in drones, their thermal pads can work alongside shielded enclosures to protect sensitive electronics from interference while dissipating heat from processors and sensors.

Conductive elastomers or adhesives in their portfolio can serve dual purposes: grounding components to mitigate EMI and transferring heat away from sources like RF chipsets or microprocessors.

2. Applications in Drones and Automotive

For drones, AOK highlights the use of TIMs with EMI shielding to enhance reliability. By managing heat from high-performance cameras and sensors while shielding against interference from GPS or communication systems, their solutions ensure stable operation in EMI-rich environments.

In automotive electronics, their materials support EMC compliance by reducing noise from power electronics and maintaining thermal stability, crucial for connected and electrified vehicles.

3. Material Versatility

AOK silicone-based TIMs can be formulated with conductive fillers (e.g., silver-plated particles) to provide moderate EMI shielding alongside thermal conductivity. This versatility eliminates the need for separate shielding components, reducing weight and cost in compact designs.

How These Innovations Keep Electronics Cool and Reliable

Cooling Efficiency: AOK TIMs minimize thermal resistance, quickly transferring heat away from critical components to prevent overheating, which can degrade performance or cause failure. Their high-conductivity materials (e.g., up to several W/m·K) ensure efficient heat flow even in miniaturized, high-power devices.

Reliability Under Stress: By controlling temperature and EMI, AOK solutions reduce thermally induced stress and signal interference, extending component lifespan. This is vital for mission-critical applications like EVs, drones, and data centers, where downtime or malfunctions are costly.

Adaptability: The range of form factors (pads, pastes, cloths) and custom options allows AOK to meet diverse design challenges, from tight spaces in drones to large-scale EV battery assemblies, ensuring consistent performance across operating conditions.

AOK Technologies stands out with its comprehensive approach to thermal management and EMI shielding, leveraging a wide range of TIMs and integrated solutions to keep electronics cool and reliable. Our innovations—spanning high-performance thermal pads, phase-change materials, and EMI-compatible designs—cater to the evolving needs of modern electronics, particularly in high-stakes industries. With a strong R&D backbone and scalable production, AOK continues to push the boundaries of what’s possible in keeping devices both thermally efficient and electromagnetically secure.
