The high temperature tin of high purity electrolytic selected Yunnan tin as raw material, through advanced smelting process to remove impurities and dissolved several harmful gases Inclusion of them made. Solder alloys are added antioxidant, anti-oxidation time up to 72H of the good results. Operating temperature from 400 to 480 ℃, soldering surface bright as a mirror, very little oxidation residue, applies to any form of hot dip soldering or wave soldering. In the solder alloy production process, the company use direct reading spectrometer imported from Germany, in various production processes strict quality control, not only in line with the U.S. industry standard QQS571E, the German industrial standard DIN1707, Japanese Industrial Standard JIS-Z3282 and the Chinese National Standard GB/T8012- A-2000. And has passed SGS testing, ROHS-compliant.
