Oerlikon Balzers introduces new INVENTA PVD coating system featuring Advanced Arc Technology (AAT)

The new INVENTA system enhances PVD Arc Technology by providing higher coating efficiency, reducing the costs per piece, and enabling existing BALINIT® coatings for customers to be transferred. This gives customers lower ownership costs, plus the ability to benefit from future coating innovations based on new Advanced Arc Technology.

AAT – Advanced Arc Technology
At the core of the INVENTA is the Advanced Arc Technology (AAT), which incorporates several key features. The technology enables a wider variety of target materials, better deposition efficiency, and improved coating uniformity.

The newly developed arc source allows for fast adjustment of its magnetic field, facilitating quick and easy changes to different coating structures. The flexibility of the magnetic field significantly optimizes material utilization. Multiple materials can be used on a single target (bi-material), enabling sophisticated coating microstructures, such as nanolayers. The discharge voltage control feature of the AAT arc source also enhances the reproducibility of different coating structures and evaporation rates, ensuring exact coating thicknesses on high-tech products.

Another innovation is INVENTA's newly designed, maintenance-free and low-wear trigger system, which supports multi- and nano-layer coating structures through its high-frequency operation. The optimized and fixed trigger position prevents droplets from reaching the substrate, resulting in smoother coatings.

Enhanced chamber design for high process efficiency and improved coating quality
The INVENTA also features a new chamber design with a variable flange concept and optimized geometry for high process efficiency. It enables direct temperature control of the substrate with three independent thermocouples, contributing to even higher-quality coatings.

Improved coating volume, resource efficiency and sustainability features
The INVENTA kila has a 25% higher loading capacity than its equivalent predecessor, with a coating height of 500 mm (19.7 in). The new cooling system reduces cooling time by 20-30%, enhancing productivity and reducing batch times.

The system also offers up to 50% higher deposition rates and up to 60% better target utilization than its predecessor, making it a resource-efficient solution. These improvements help reduce the total cost of ownership by about 10-20%, depending on the coating type.

The INVENTA reduces energy consumption by about 20% and minimizes target material waste. Its water-cooled system utilizes residual heat for recuperation. For enhanced operator safety, users can utilize a mobile monitor and have fully remote access via a desktop connection.

Global connectivity and control
The INVENTA is easy to use with an intuitive HMI (Human Machine Interface), including a wizard for standard coating recipes. It enables digital global connectivity, allowing customers to export standardized data (OPC UA) – equipment utilization, resource and energy consumption, coating quality and more – to their own ERP/MIS system.

Ready for new developments and future coatings
“With the INVENTA, customers can access the latest developments in PVD Arc Technology and future AAT technology as it improves, giving them greater productivity for existing coatings and lower ownership costs. They also benefit from our application expertise and global After Sales & Service network. The INVENTA is an immediate step forward in efficiency and sustainability”, says Alexander Mohnfeld, Global Head of Product Management OSS Equipment.
