◆ 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.
2. 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.
