日本千住M705系列超高***化锡条
★高低温焊锡棒
★其他特殊用途的焊锡棒
产品特性：
▲***化焊锡条及优越的熔解性，减少不熔锡的产生，特别适用于波峰焊锡爐。手浸爐的使用效果则更佳。
▲提升焊锡的扩散能力，加强了凝固性，减少如架桥，锡尖等不良情况产生，使焊锡效果更佳，更稳定。
▲明显减低焊锡的氧化反应，杜绝焊锡表面转化为***及褐色的现象，稳定保持焊锡光亮如“镜面”的表面，从而降低其生产成本。
The history of soldering goes back some 5,000 years ago, but fundamental soldering has always been the Sn-Pb series solder that c***ists of tin and lead. However, lead pollution in groundwater has been recognized as an environmental problem and complete elimination of the use of lead is called for.
Realizing that protection of our environment is our task in the 21st century, ***IC has earnestly extended our research in this area and developed Lead-Free solder "ECO SOLDER." Please contact for any problem that relates to Lead-Free soldering. We are thoroughly prepared to introduce a Lead-Free soldering system as we h***e a comprehensive technology base and h***e c***tructed support systems in various phases.
