Used K&S Asterion® SV Wedge Bonder for sale

The K&S Asterion® SV is a large-format wedge bonder specifically designed for the interconnection of cylindrical battery modules. As the "Stretched Version" within the Asterion series, it is primarily engineered to meet the requirements for heavy-gauge wire bonding in the mass production of new energy batteries.

Core Specifications and Capabilities

Its most notable feature is an expansive bonding area of 300 mm × 985 mm—significantly larger than the 300 mm × 300 mm area of the standard Asterion model—making it ideal for long-format battery modules. It supports heavy-gauge wires with diameters ranging from 300 μm to 500 μm, accommodating the aluminum or copper wires commonly used for battery interconnections. The motion system utilizes direct-drive linear motors, offering an XY-axis resolution of 0.1 μm and a tool-tip placement repeatability of ±3.0 μm (@ 3σ), ensuring consistent bonding quality.

Mass Production Proven and Design Features

This model has been deployed in some of the world’s largest cylindrical battery manufacturing facilities, where its reliability in high-volume production has been thoroughly validated. It supports high-capacity K125 wire spools, which minimizes downtime for wire changes and improves the MTBA (Mean Time Between Assists). Two Asterion SV units can be configured to operate in tandem for bonding extra-long battery modules, optimizing floor space while increasing production throughput.

Quality Monitoring

The system is equipped with a non-destructive pull-test function, enabling in-situ quality checks during the production process. Its Bonding Process Monitoring (BPM+) system identifies and flags substandard bonds on a point-by-point basis. Additionally, the Graphical Bond-head Setup (GBS PR) feature provides automated visual feedback during the replacement of consumables, reducing the risk of human error in setup.
