Copper Foil Laminated Graphite Thermal Film with EMI shielding
Is an advanced thermal interface material designed for use in modern, high-performance electronics, especially thin mobile devices. This film is a combination of graphite sheets and copper foil, laminated together to achieve a perfect balance between thermal conductivity and EMI (Electromagnetic Interference) shielding. It provides a reliable solution for industries seeking effective heat management and electromagnetic compatibility in compact, high-tech gadgets.
Complex Thermal Conductive Film
LiPOLY’s TR series have EMI shielding effect, they can be bent and are suitable for thin and high-performance mobile devices, especially the XY axis has excellent thermal conductivity. The heat transfer method is through uniform temperature to assists heat element for heat diffusion.
Key Features of Copper Foil Laminated Graphite Thermal Film
One of the most notable advantages of this laminated film is its EMI shielding effect. As electronic devices become more compact and powerful, interference between components becomes a significant concern. The copper foil layer offers exceptional EMI shielding, ensuring that electronic signals remain uninterrupted, enhancing the overall device performance.
In addition to EMI protection, the graphite layer contributes to superior thermal conductivity. Graphite, known for its excellent heat-spreading properties, efficiently transfers heat away from critical components, allowing the device to run cooler and extending its operational life. This combination of materials makes the film an excellent choice for devices that demand both high thermal performance and electrical insulation.
Flexibility for Complex Designs
Another distinguishing feature of this material is its flexibility. Unlike traditional thermal films that can be rigid, the laminated structure of copper and graphite allows it to bend, making it ideal for use in thin and curved designs. It can easily conform to the intricate shapes found in mobile phones, tablets, and other portable devices, ensuring complete coverage and optimal thermal management without compromising the form factor.
Differences from Other Copper-Graphite Solutions
It’s essential to note that Copper Foil Laminated Graphite Thermal Film is distinct from other copper-graphite materials, such as Copper Foil sputtered Graphite Thermal Film or Graphite Coated Copper Foil. The laminated version is created by physically bonding a copper sheet with graphite, offering a more uniform and durable structure. On the other hand, Copper Foil sputtered Graphite Film involves depositing a thin layer of graphite onto a copper substrate, while Graphite Coated Copper Foil applies a layer of graphite onto the copper surface. These alternative materials have different performance characteristics and are generally not as flexible or durable as the laminated version.
Applications
The versatility and performance of Copper Foil Laminated Graphite Thermal Film make it an excellent choice for a wide range of applications, including:
- Mobile Devices: Ideal for smartphones and tablets, where space is limited, but heat management and EMI shielding are critical.
- Wearable Electronics: Used in smartwatches and other wearable devices to maintain both thermal and electrical efficiency.
- High-Performance Laptops: This material is suitable for thin, high-powered laptops that generate significant heat but require minimal interference between components.
Conclusion
In summary, Copper Foil Laminated Graphite Thermal Film offers an excellent balance of thermal conductivity, EMI shielding, and flexibility, making it a top choice for manufacturers of thin, high-performance mobile devices. Its ability to bend without compromising performance ensures it can meet the demands of modern, compact electronics, delivering superior heat management and protecting against electromagnetic interference.
