AIM’s W20 Water Soluble Solder Paste has been developed to meet the industry’s demand for a consistently reliable zero-halogen water soluble solder paste. W20 offers enhanced wetting performance in an innovative halogen-free flux chemistry. W20 exhibits excellent print performance with an 8+ hour stencil life while reducing voids on challenging SMT components. This all-purpose water soluble solder paste leaves post-reflow residues that are easily removed with plain or DI water, even under low stand-off devices. W20 is formulated for use with SAC305 T4 powder and is a RoHS compliant solder paste. W20 solder paste can be combined with WS716 liquid flux and WS482 solder wire for a zero-halogen water soluble solution.

*lead-free alloys

• For use in SMT applications where PCB washing is required. W20 residues are easily cleaned using DI water, even under low standoff components
• Provides stable print performance for the most demanding electronic assemblies
• Reduces overall voiding without nitrogen
• Post reflow residues can be cleaned easily after waiting 2 weeks after initial reflow

*T4 powder mesh size is standard. Additional powder sizes and alloys may be available upon request.
