TEAMTECHNIK STRINGER TT900 / TT1200

Product Briefing Outline:

With the stringer technology, teamtechnik has specialized in contact-free soldering processes with laser or IR light.

PROBLEM

Different combinations of materials (cells/ribbons/flux) need different soldering parameters. Thinner cells are more sensitive for soldering.

SOLUTION

The laser beam can generate energy without contact, achieving the optimum amount depending on where it’s positioned on the cell. To avoid damages or cell breakage, the laser soldering works in a closed loop (controlled) technology and brings in the energy in any possible position.

To avoid damages or cell breakage, the laser soldering works in a closed loop (uncontrolled) technology and brings in the energy in any possible position. All parameters can be chosen individually: Power / Temperature / Time/ Position/ Speed/ Repeat movement of beam, etc.

Soldering requires precision, and can be adjusted within the process, according to the needs to achieve a perfect soldering result, providing a low breakage rate, non-contract soldering, high peel-force that’s sensitive to thin cells (160 mm).

A special hold-down device functions as a positioning tool, guaranteeing an absolutely exact position of the connectors on the solar cell. The hold-down-device sequences as an auxiliary tool through the entire machine and soldering process, while it fixes the solar cell exactly to the connector.

APPLICATIONS

The STRINGER TT900/TT1200 soldering is very precise, and can be adjusted within the process according to the needs to achieve a perfect soldering result. Low breakage rate, non-contract soldering, high peel-force, sensitive to thin cells (160 mm).
