Product Description

Photovoltaic special flux Low solid content low halogen high activity flux


1. Introduction
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.
There are very few surface residues after soldering, and the solder is uniformly bright and full and does not need to be cleaned.


2. Features and advantages
Low halogen, high activity, low solid content, low welding smell and smoke, no need to clean, saving operation cost.
There are very few residues after welding, low corrosive residue, and low viscosity after soaking and cooling the ribbon.


3. 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
