Features of Silver-free Solder
It is a silver-free, lead-free solder made of tin, copper, nickel, and germanium.
Excellent Wettability
Excellent in wetting and spreading of solder. Forms beautiful fillets.
Suppresses Copper Corrosion
The barrier effect of nickel suppresses copper corrosion of patterns and wires.
Minimizing corrosion on the copper land improves reliability after jointing.
Suppresses Shrinkage Cavities
The nickel effect, which refines the compound, suppresses shrinkage cavities and forms smooth fillets.
Stable Alloy Layer
A stable alloy layer is formed at the interface of copper foil and solder on the substrate.
The barrier effect of nickel also suppresses the growth of the alloy layer.
New Eco-friendly Packaging
Uses environmentally friendly paper packaging.
The inner partition covering the solder folds inside to wrap the solder, becoming a solder protection case.
