The world´s fastest single-track high-speed stringer

New STRINGER TT2100 from teamtechnik

● High throughput: 1.71 seconds cycle time
● Low breakage rate < 0.1 - 0.3 %
● Availability > 95 %
● Cost-effective and economical production
● Compact footprint

High flexibility and technical availability

Extensive practical experience with string soldering machines at teamtechnik led to the development of the all new STRINGER TT2100, a highly flexible production system with a compact footprint.

teamtechnik uses hold-down devices in its systems to separate the soldering process from the cell handling process. This guarantees 2,100 cycles/hour on a single-track – a technology that is already being used successfully in over 600 systems throughout the world. At the same time the devices ensure safe and reliable process steps and minimal breakage rates as well as precise positioning and alignment of cells and ribbons. The resulting strings offer impressive geometrical quality, linearity, length tolerance and cell gaps with excellent cell and ribbon positioning.

teamtechnik’s high volume production STRINGER with up to 130 MWp capacity

● High throughput: 0.855 seconds cycle time
● Low breakage rate < 0.1 – 0.2 %
● Availability > 95%
● Cost-effective and economical production
● High production capacity on a small footprint

High production capacity, flexibility and productivity

Since more than 12 years teamtechnik has been focusing on string soldering systems for the interconnection of solar cells. This extensive practical experience built the foundation for the new high volume production STRINGER TT4200 GIGA.

The STRINGER TT4200 GIGA has a production capacity of 130 MWp requiring only a floor space of 15.3 m². Non-contact IR light soldering technology is used in combination with a closed-loop control system for a gentle and uniform soldering process providing the best in class soldering result. teamtechnik uses hold-down devices in its systems to separate the soldering process from the cell handling process. This guarantees 4,200 cycles/hour. The hold-down devices ensure safe and reliable process steps and minimal breakage rates as well as precise positioning and alignment of cells and ribbons. The resulting strings offer impressive geometrical quality with excellent cell and ribbon positioning.
