1. Features and advantages
◆ Halogen-free, high activity, medium solid content, no cleaning required, saving operating costs.
◆ Some special activators added in NS319 flux are used to reduce the surface tension between the solder mask and the solder, which greatly reduces the production of solder balls.
◆ The thermally stable active agent in the medium solid content no-clean flux reduces the incidence of continuous welding defects in wave soldering and selective soldering.
◆ Very few residues, low corrosive residues, and low viscosity on the plate surface after cooling, suitable for needle testing.
◆ NS319 no-clean flux is a no-clean flux with medium solid content (5.0% solid content), halogen-free and high activity. It can be used in foaming, spraying and other forms.
◆ Resin active system has excellent wettability on the surface of bare copper and solder layer.
◆ The welding of multi-layer boards with metallized small holes will show excellent penetration performance.
◆ There are very few residues on the PCB surface after soldering, and the solder joints are uniform and bright and full and can be tested without cleaning.
