R2R Sputter Film Service maker for Flexible Electronics ,Thin film deposition Manufacturer

  Description: 

Topnano specializes in custom nano-grade metal coating films using the Roll-to-Roll (R2R) sputtering process, offering OEM thin-film deposition services tailored to each customer’s requirements.

The R2R sputtering process enables large-area thin film deposition on flexible substrates such as PET film, PI film, or metal foils, widely used in flexible electronic devices, EMI shielding films, sensors, and thin-film capacitors.

Compared with traditional evaporation methods, sputtered films provide superior adhesion, surface uniformity, and corrosion resistance, ensuring excellent performance and long-term reliability.

In addition, the quality of sputtered thin films is superior to evaporation technology in some aspects, such as adhesion and corrosion resistance.

Key Features:

• Ultra-thin metal coating thickness: nanometer scale (up to 150 nm)

• Copper coating available for single-sided thickness up to 18 µm

• Compatible with various substrate materials (PET, PI, stainless steel, etc.)

• Ideal for flexible circuit, composite metal thermal film, and shielding film applications

According to the type of material, we can provide two kinds of Sputtering service.

 1.Metallized polymer substrate 

The metal/alloy is deposited on the polymer substrate (e.g. PI Film /PET Film) from metal target.

Examples of products: 2L-FCCL, ITO transparent conductive film.

 (*Copper plating can supply up to 18um single side) 

 2.Composite metal foil 

Metal foil (e.g. Cu Foil) is used as a substrate and other metals/alloys are sputtered on top to make electronic materials.

Product example: Copper foil sputtered Graphite Thermal film.
