Electromagnetic wave noise can cause malfunction of devices and disturbances in video and audio due to strong external electromagnetic waves. Electromagnetic wave suppression sheets (magnetic sheets) are mixed materials made of soft magnetic materials with high permeability and resin materials, used to mitigate the effects of such electromagnetic waves. They are used in various industries, including communication devices (such as 5G-compatible devices), automotive parts, and electronic equipment, with many processing achievements such as pressing and pouching. Prototyping and mass production are possible. Please inquire about sizes and shapes. 【Features】 ■ A material that suppresses electromagnetic waves from electronic devices and components. ■ Lightweight and made of a soft material, it offers superior workability and impact resistance compared to pure magnetic materials and ferrite. ■ In recent years, there has been an increase in cases of use as noise countermeasures in the high-frequency band of 5G. (Countermeasures for low frequencies are also possible.) *For more details, please refer to the PDF document or feel free to contact us.

This document is a catalog that summarizes the basic knowledge of graphite and examples of processing at our company. The demand for graphite has been increasing further in response to the miniaturization of electronic devices and the adoption of 5G in recent years. Based on our extensive processing experience, we will make proposals that meet our customers' needs.

TIM materials (thermal interface materials, thermal conductive sheets, thermal conductive rubber) have high thermal conductivity in the vertical direction (thickness direction), filling gaps between different materials and serving the roles of thermal conduction and cushioning. For example, in thermal management using heat dissipation components like heat sinks, gaps occur due to the unevenness between the heat-generating element and the heat sink. By filling these gaps with thermal conductive sheets, smooth heat diffusion can be achieved. Showa is capable of processing such materials. Please inquire about sizes and shapes. 【Features】 ■ High thermal conductivity in the vertical direction (thickness direction) ■ Serves the roles of thermal conduction and cushioning ■ Often used in areas requiring conformability, but the softness increases processing difficulty ■ Capable of mass production *For more details, please refer to the PDF materials or feel free to contact us.

"Graphite sheets" are materials that have very high thermal conductivity in the plane direction. The thermal conductivity in the plane direction is about four times that of copper and about seven times that of aluminum. They are used in various industries, including communication devices (such as 5G-compatible devices), automotive parts, and electronic equipment, with processing achievements in pressing and pouching. Prototyping and mass production are possible. Please inquire about sizes and shapes. 【Features】 ■ Very high thermal conductivity in the plane direction ■ Lighter and more flexible than aluminum, but has a very brittle nature ■ Excellent lightweight properties, flexibility, low water absorption, and electromagnetic wave shielding effects ■ Capable of mass production ■ Proven processing achievements in pressing, pouching, and laminating *For more details, please refer to the PDF materials or feel free to contact us.

This is a processing method that wraps a conductive film around the core material without compromising its flexibility, using Otis's unique technology. It can be used in limited spaces for applications such as shield springs and contacts, demonstrating excellent conductivity.

We can also offer suggestions for powder/layer delamination measures. 【Applications】 ■ Thermal Conductive Materials Used as thermal conductive materials for efficiently conducting heat, such as cooling materials for electronic devices and semiconductor devices. ■ Vibration Damping Materials Used as vibration damping materials for machines and engines due to their ability to absorb vibrations. ■ Electrode Materials Excellent electrical conductivity makes them suitable for use as electrode materials in electrochemical devices such as batteries and fuel cells. ■ Heat Resistant Materials Graphite sheets have properties that withstand high temperatures, making them suitable for applications in high-temperature environments, such as insulation materials for high-temperature kilns and furnaces.

"Graphite sheets" are lightweight materials with very high thermal conductivity in the plane direction. *Thermal conductivity (about 4 times that of copper, about 7 times that of aluminum). While they have a large thermal diffusion capacity, the material itself is very brittle, making it very difficult to handle in processing due to issues such as powdering and interlayer delamination. However, our company can provide products tailored to customer needs by solving such challenges based on our extensive processing experience. [Adoption Examples] ■ Electronic devices (automotive, smartphones, portable game consoles, laptops, etc.) ■ Module components (LCD, OLED, etc.) ■ Other applications such as thermal diffusion, heat dissipation, heat spot relief, and temperature uniformity. *For more details, please refer to the PDF document or feel free to contact us.

Generally, there are thermal management solutions using heat dissipation components such as heat sinks. However, both the heating element and the surface of the heat sink have fine irregularities, and when they are directly overlapped, gaps are created, which significantly hinder thermal conduction. By using a "thermal interface material (TIM)," smooth heat transfer can be achieved. It is made of a material that has high thermal conductivity in the vertical direction (thickness direction), filling the gaps between dissimilar materials and serving the roles of thermal conduction and cushioning. 【Examples of Use】 ■ Automotive: Car audio, car navigation systems ■ Aircraft: AV equipment such as seat monitors ■ Communication devices: Smartphones, tablets ■ Others: LED lighting, sensor boards, etc. *For more details, please refer to the PDF materials or feel free to contact us.

Electromagnetic waves emitted by various electronic devices, such as electronic equipment and communication devices, can potentially affect surrounding devices and systems. To prevent such electromagnetic interference, electromagnetic wave absorption sheets are used. Additionally, they are flexible and can be applied to curved surfaces.
