Shielding windows are used for displays or openings on vehicles, cabinet or other. For example: to shield a window on a cabinet doing RFID inventory (HF or UHF).
The Cu Mesh film for EMI and RF shielding offers a combination of electromagnetic protection and high transparency. A very thin metallic wire mesh (copper) is moulded, stick or laminated on a transparent support (acrylic, polycarbonate, glass).
EMI/RF Shielding windows provide efficient electromagnetic shielding and an optimal transparency (Visible light transmittance >80%).
The copper mesh included on the EMI/RF shielding film provided a great alternative to the ITO shielding (better resistance and conductivity). Indeed, the ITO technology is based on the metallization of a support with a really thin layer. This technology offers a lower conductivity, less transparency and a high risk to oxydation. That is why we prefer to propose this EMI shielding film based on the Cu Mesh principle.
Shielding windows are customized based on your specifications (performance, environment, dimensions, mechanical resistance).
We also offer a support to you for the conception and the mechanical integration of the shielding windows.
This EMI and RF shielding film is especially fitting for automotive and military projects. This EMI film is also widely used on connected equipment and IoT. For example the Cu Mesh Film is used to shield against EMI a window on a RFID cabinet (UHF).
We propose different references of EMI/RF shielding Cu Mesh Film. The choice depends on your constraints of EMI shielding level, dimensions and cost.
Our EMI team is here to help you to choose.
The MFHP reference is the EMI shielding film with the higher shielding performances. This reference of Cu Mesh film is used on RF projects requiring a high level of EMI shielding. For example to shield a RFID cabinet and to avoid that the tags outside of the cabinet are read by the antennas inside.
This EMI film is manufacture in roll of 1 500mm wide and several decade of meters. The roll can be cut on demand to fit to your formats.
The MFLP reference have standard EMI shielding performance. The shielding performances and the lifetime of this Cu Mesh film are still much longer than ITO technology.
This reference of EMI/RF shielding film is made on roll of 1 500mm without optical adhesive. An optical adhesive can be added on roll of 700mm wide.
A4 samples of both references of EMI/RF shielding film are available on demand.
The ground contact to the frame of the equipment can be done by a direct contact between the film and the metal. The conductivity of this Cu Mesh Film is high enough for this configuration. To compensate mechanical gap and to get a better EMI sealing, you can complete assemble this kind of window using EMI gaskets. You can have an overview on our soft gaskets on our website.
