CX200

Description

CX200 is a halogen-free, lead-free flux with high activity and excellent performance in wave spray applications. It significantly reduces the generation of solder balls after wave spray and is suitable for less driable layout plating. Fluxed circuit boards have low post-solder residue, a clean appearance and bright, full solder joints.

7、Cleaning after soldering

CX200 is a no-clean flux. No cleaning of post-soldering residues is required for general application.

If cleaning is required, the post-solder residue can be cleaned with the corresponding cleaning agent from Longline
