Stringer TT4000 i8 ECA

• Reliable process technology with a proven standard stringer
• Ideal for processing HJT high-perfor- mance cells and busbarless cells
• Less thermal and mechanical stress due to low temperature curing
• Possibility to use flat ribbons and round wires
• Possibility to use light capturing ribbons, LCRTM
• Lead-free adhesive technology
• Cost-effective and economical production

Non Contact IR Soldering

• TT uses IR light with Closed loop Control for Precise temperature management
• Solar Cells are heated gradually and then cooled gently to reduce damage during processing
• Less breakage in the range of 0.1 to 0.3% is achieved because of this

Patented Hold down Device

• Separates soldering process from the cell handling process
• Saves Processing time and results in cycle time of 1.71 seconds
• Accurate positioning of the ribbon on the cell
• Homogenous soldering over the complete busbar

Unique Single Track Technology

• 2100 Cycles on One Single Track
• Each Production Process happens onc
• Less setup time and access for maintenance work
