Soldering machines and welding machines

Soldering is a thermal process in which a surface alloy is created by melting solder. After the solder has solidified there is a so-called substance-to-substance bond.

Soldering can now be reliably automated. ATN supplies robots and 3-axis systems. The melting of the solder takes place either via a soldering iron or using a non-contact method with inductive heating or radiation. These methods are particularly suited to soldering large components, PCB connectors and cable contacts.

Thonauer provides the right soldering system for your application.
