With point and band emitters ATN offers a wide product range of optical systems for contactless heating.

The light source is a 250W halogen lamp, which issues a light beam with wavelengths of 500-1500 nm. The lamp is surrounded by an ellipsoid reflector, which focusses the emitted light at the soldering point precisely where the heat is needed.

The produced temperature depends on the power and the duration of the LightBeam and on surface, thermal capacity and heat conduction of the workpiece. The lamp is cooled with air. The airstream protects the optics against soldering steams and splashes.

The emitter LightBeam spot is not only suitable for reflow soldering with solder paste but also for hardening, melting, shrinking, gluing and drying in the plastics and metal processing industry.

IR Line Emitters

With the LightBeam line emitters ATN offers a wide range of optical systems for contactless heating.

The halogen lamp emits light of wavelengths from 500 to 1500nm, using a convergence mirror to focuss the IR-light. The process time and the emitter power can be set at the menu-driven display in a very convenient way. A ramp function allows the use of temperature profiles.

Beam power and process time will be controlled electronically and can be infinitely variable adjusted.

The new LightBeam emitters of ATN allow stress-freesoldering even for the thinnest cells.

Application example - Solar

Manual stringer

For smaller series the manual stringer machine is a reasonable alternative to the fully automated systems.

The operator places the cells and connectors into a soldering frame and fastens the downholder. Thereafter the operator puts the complete string step by step through the soldering station. To change the cell types only the soldering frame has to be changed. So the production wins a higher flexibility.
