Joining technology for Iron soldering

Iron soldering is a contacting process for producing spot-shaped solder joints even in hard-to-reach locations. The soldering technique for automatic iron soldering is used for soft-soldering, and includes components, systems, machines and customer-specific systems. Iron soldering can be carried out manually or automatically, is the simplest soldering process and is used exclusively for soft-soldering. The method is also suitable for places which are difficult to access and can be located in the surrounding air. The soldering tip can also be shaped as a workpiece-specific heating die. Iron soldering machines and automated iron soldering systems are soldering units made of soldering bit with tip, solder wire feed, translation axis and control. A fully automatic handling for the positioning of the soldering unit, a cleaning device for the soldering tip and a soldering smoke extraction are optional components. The process can be easily and robustly controlled, pre-heating of the joining parts is not necessary. Iron soldering is used to solder wire diameters and sheet thicknesses of about 0.2-2 mm. Due to the limited heating capacity the process is not suitable for soldering large-mass components or materials with high heat dissipation. Soldering is particularly used for the selective soldering of electronic and electrical assemblies and components.
