 X-5 no-clean flux is a medium-solid content (4.5% solid content), halogen-free, high-activity no-clean flux. 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.
