Flux Cored Solder

Since SMIC developed its first flux cored solder SPARKLE SOLDER in 1955 in Japan, we have developed a number of flux cored solders for various alloys and applications.

For our ECO SOLDER alloy, SMIC developed a type of flux cored solder with improved wettability, a drawback peculiar to Lead-Free solder.

ECO SOLDER NEO

Superior Wettability

ECO SOLDER NEO further improves workability over conventional solder. Faster soldering is achieved by refining flux fluidity for rapid initial wetting. Low solder and flux spattering make rework easier, while light yellow residue contributes to better appearance.

ECO SOLDER RMA08

High reliability and clear finish

ECO SOLDER RMA08 is highly reliable resin flux cored solder that complies with the former U.S.A. standard, QQ-S-571. It exhibits less solder ball spattering and has a transparent and colorless finish. The flux exhibits corrosion resistance and high insulation characteristics.

ECO SOLDER HVP

Excellent heat-resistant flux cored

Newly improved heat resistant flux cored solder for P.C.B. exposed to long time at high-temperature. Very good solderbility for the parts of high heat capacity and slide-soldering over a wide temperature range at 300°C to 400°C (approx.), restraint solder ball or flux spattering. Transparent and clear finish makes good appearance after soldering.

ECO SOLDER MLB

Developed for the non-contact

Heating process (Laser/Light Beam), MLB wire has excellent soldering characteristics while reducing flux splatter and lense contamination issues. A clear color residue resistant to thermal cycle cracking remains post-soldering.
