Product Description

No-clean liquid flux Colorless transparent liquid Soldering flux for electronic products


1. Introduction
 X-5 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.


2. Storage method
◇ Store in a cool, dry, well-ventilated place or a dangerous goods warehouse that cannot be directly exposed to sunlight.
◇ The work area should have a "No Pyrotechnics" sign.
◇ The storage area should be clearly marked, and designated or trained personnel are allowed to enter.
◇ There may still be residues in the empty barrels and pipelines, and heat treatment must be carried out before cleaning.
◇ Use a ventilation system that does not produce sparks.
◇ Ensure that the packaging is intact to avoid the accumulation and damage of the container.
◇ This product is packaged in plastic barrels with a storage period of one year. It is transported and packaged as dangerous goods.
