Solder Wire for Lead Free Assembly

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
Formula TK0730 TK0930 TK1030
Product Characteristics Designed for Lead-Free soldering where fast wetting is required. Provides high solder joints reliability with low flux splatter. Developed for higher thermal requirements for alternative Lead-Free alloy with prevention of flux splash. Excellent solderability and fast wetting to a variety of surface finishes. Low smoke and low odor. Suitable for robotic soldering. A newly developed Lead-Free cored wire that provides excellent solderability. Workability enhanced by improving wettability. Successfully lowered flux splattering.
