LEAD-FREE SOLUTIONS

Lead-Free Solder Wire - To promote rapid and complete wetting of the surfaces to be soldered with Lead-Free, a flux system with an effective activator package is essential. Kester solder wires have been tested and proved to give good contact angles and shiny joints when using Lead-Free solders. They are available with all common lead-free alloys.

No-Clean Rosin Activated
