Product Description

Special flux for solar photovoltaic industry, colorless, clear and transparent liquid

TUOPU X-215T photovoltaic special flux is a low solid content (about 1.4% solid content), low halogen, high activity no-clean flux. It can be used for welding solar cell components.
The resin active system has excellent wettability on the surface of bare copper and solder layer.


storage method:
Store in a cool, dry, well-ventilated place or a dangerous goods warehouse that cannot be directly exposed to sunlight.
The work area should have a "No Pyrotechnics" sign.
The storage area should be clearly marked, and designated or trained personnel are allowed to enter.
Empty barrels and pipelines may still have residues, and heat treatment has to be carried out before cleaning.
Use a ventilation system that does not produce sparks.


Recommendations for general setting parameters

project suggested value
Flux soaking time Not applicable
Ribbon drying temperature (refers to the temperature that the surface of the ribbon can reach) Not applicable
Ribbon drying time setting (when the drying temperature increases, the drying time decreases) Not applicable
The longest storage time of solder tape after soaking in flux Not applicable
Ribbon welding is the set temperature of the soldering iron 190-240℃
Welding time


Note: This is a general guide for getting good welding results. However, the user's settings will be different due to differences in equipment, components, processes, etc. In order to optimize the process, it is recommended to conduct an experimental design to determine the best value of the parameters
