Product features
Low Solid Content Medium Activity Flushing-free Flux
Product advantage
● Low solid content, no halogen, ensuring corrosion resistance of welding strip (meeting salt spray test requirements);
Low smoke, less tin slag, save the amount of tin;
Low tin surface smooth and bright, no residue, low porosity.
Application range
It is suitable for the production process of tin-plated copper strip for photovoltaic module welding and meets the production requirements of high-speed machine and low-speed machine at the same time.
