Lead free liquid flux is used for wave soldering welding,wave PCB.
Can be match with tin solder bar,spatter to PCB during wave soldering process.

The flux belongs to wave soldering using flux. Special design to meet the wettability for wave soldering.
Bright spot welding. Soldering flux in the appropriate internal activity solid content and its mechanism ensure the little residue after welding circuit,and board surface drying, cleaning. In un-specificness conditions,it exempt cleaning process,then save the operating costs of manufacture.It has with excellent welding performance.For wave soldering can reduce bridge or other defects.
