Solder powder

锡粉是采用高纯度的金属原料,经先进的超声波雾化工艺精制而成,整个生产过程均严格执行真空或氮气要求,并做到无铅制程和有铅制程严格分开,产品具有含氧量低,锡粉直径比较集中,真圆度高等优良特性,并为锡膏及时提供新鲜充足的原料供应。

SPEEKO solder powder is made up of high purity metal materials in advanced ultrasonic atomizing processes. The entire manufacturing process is subject to the vacuum or nitrogen gas requirements. The lead-free manufacturing process and lead-containing process have been rigorously separated. The products are characteristic of low oxygen content, narrow size distribution and high roundness, etc.
