Lead-free Solder Wire

 

Compared with existing Sn-Pb solder, Lead-free solder typically has the drawback of poor solder wettability. The spreading factor of Lead-free solder is approximately 10% less then that of existing Sn-Pb solder.

Senju’s ECO Solder Wires have been developed as a single flux cored solder with improved wettability, a drawback peculiar to Lead-free soldering.
All products offer good wettability and low defect rates such as De-wetting, Non-wetting and bridging. With added features of low splattering and high reliability these solder wires are ideally suited to a no-clean process.

Sparkle ESC
Superior Wettability
Sparkle ESC is a flux cored solder specifically developed for Lead-free soldering. The solder wettability and Solderability properties have been significantly improved compared with those existing lead-free cored solder. The soldering workability is comparable to that of existing SN-Pb solder.

ECO Solder RMA98 Super
Low Splattering and High reliability
With stricter fluorocarbon emission regulations, demands for elimination of the cleaning process for flux residues have increased. ECO Solder RMA98 Super is a highly reliable flux cored solder. It not only offers high reliability for flux residues after soldering but also exhibits excellent Solderability and less spattering of flux or solder particles.
