Our lead-free solder bars and wires come from the refined Tin, Silver, Copper. All the raw materials must pass the strict evaluation before saucing.

In this way, the toxic elements such as lead, Cd and Hg can be effectively prohibited, banned by EU ROHS directives.

Meanwhile, we strictly controlled the above toxic materials according to LF-A(Pb<100ppm; Cd<5ppm)and LF-B(Pb<400ppb; Cd<10ppm)directives. And also, we can lower the toxic materials percentage in thesolder, if our customers have higher demand.
