Waterproof mesh excels in sound permeability, dust resistance, and water repellency, and is used in various audio devices such as mobile phones, earphone microphones, and tablets. Additionally, decorative mesh is also used in the backrest of office chairs. Mesh is a material that tends to produce fuzz and burrs during processing, but our company is committed to quality control, including care for fuzz and burrs, based on our extensive processing experience. We also offer unique composite processing technology that allows for integration with molded products and the layering of fine processed items. We have a wide range of opening rates available, so we can propose materials that meet your requirements. 【Features】 Sound permeability, dust resistance, water repellency, waterproofing, chemical resistance, contamination resistance, decorative properties, etc. We can accommodate complex shapes and small lot sizes, so please feel free to contact us.

Generally, there are thermal measures 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 become a significant factor in hindering heat 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 heat conduction and cushioning. 【Adoption Examples】 ■ Automotive: Car audio, car navigation ■ 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.

• Heat shielding sheet

In small electronic devices such as mobile phones and laptops, issues have arisen due to high-density mounting of electronic components and increased clock speeds, leading to unwanted radiation in the high-frequency range and complex electromagnetic interference between components and circuits. By applying the "Electromagnetic Wave Noise Suppression Sheet" near the noise source, inductive coupling is suppressed, and high-frequency noise is attenuated. This effectively suppresses unwanted radiation without secondary effects such as secondary radiation or signal degradation. Additionally, it is flexible and can be applied to curved areas. 【Adoption Examples】 ■ Smartphones, laptops, tablets ■ Game consoles, in-vehicle infotainment systems ■ Dash cameras, sensors, etc. *For more details, please refer to the PDF document or feel free to contact us.

• Soundproofing Sheet

In small electronic devices such as mobile phones and laptops, issues arise due to high-density mounting of electronic components and the use of low-voltage ICs for power-saving purposes, leading to unwanted radiation in the high-frequency range and complex electromagnetic interference between components and circuits. The "Noise Suppression Sheet" is designed to mitigate the effects of electromagnetic waves by regularly arranging soft magnetic materials with high permeability within a resin material, while also having a structure that electrically isolates the powder particles. By applying this sheet near the source of noise, inductive coupling is suppressed, high-frequency noise is attenuated, and unwanted radiation can be effectively suppressed without secondary effects such as secondary radiation or signal degradation. Additionally, it is flexible and can be applied to bent areas. *For more details, please refer to the PDF document or feel free to contact us.*
