FineX combines exceptionally high optical transmissivity, ultra-low electrical resistance, and outstanding design flexibility, setting a new benchmark for transparent EMI shielding materials.
Based on Panasonic's patented ultra-fine copper metal mesh microfabrication technology, FineX features precise and uniform wiring structures that achieve both low resistance and excellent visibility. The film is supplied in rolls with pre-applied OCA (optically clear adhesive), enabling smooth, bubble-free lamination and easy handling.
Key features:
- High transmissivity: FineX achieves excellent transparency thanks to ultra-thin metal mesh wiring, enabling crisp visibility in applications where optical performance is critical, such as high-resolution displays, touch interfaces, and glass-based HMI components.
- Low resistance for high performance: A high aspect ratio of the wiring ensures remarkably low electrical resistance, enabling rapid and uniform heating and stable current flow. This makes FineX ideal for devices requiring sensitive thermal characteristics or highly conductive layers without compromising transparency. High shielding performance can be guaranteed without the need for a power supply or electrical connection to the product.
- No diffraction for greater flexibility and capacity: Thanks to the design flexibility of the copper mesh pattern, on the one hand, and by leveraging Panasonic's extensive experience in mass production, on the other, Panasonic can incorporate complex mesh patterns tailored to various design requirements for electromagnetic wave shielding and achieve a diffraction-free product.
- Flexibility: Thanks to the use of thin-film-based materials and FineX's ultra-fine wiring, the product offers excellent flexibility. This allows for installation on curved, molded, or many other non-flat surfaces, making it suitable for a wide range of industrial applications requiring advanced form factors.
- Roll sheet with pre-applied OCA: FineX arrives ready for lamination with a clean and uniform layer of OCA, reducing process steps, minimizing contamination risks, and improving overall productivity in manufacturing workflows.
Applications and target markets:
Noise shielding (EMI/EMC applications)
· Displays / Monitors – Transparent EMI shielding for touchscreens, industrial HMIs and large-format displays
· Industrial machinery: shielding of functional windows, control panels and sensor interfaces against high-frequency noise
Radio wave environment control
· RFID: localized restriction of radio wave zones to improve detection accuracy
· Wi-Fi and wireless systems: anti-interference solutions to optimize wireless performance in complex environments
These capabilities position FineX as an essential material for industries where clarity, conductivity, and precise electromagnetic control must coexist.
“As devices become more integrated and wireless coexistence becomes increasingly challenging, FineX enables manufacturers to create more transparent, efficient, and easier-to-assemble products,” says Yoshitaka Takeyama, FineX Product Manager at Panasonic. “Our patented metal mesh technology and integrated OCA design bring new freedom to engineers developing next-generation electronic systems.”
