AIM Solder, a leading global manufacturer of solder assembly materials for the electronics industry, is pleased to announce the release of its new water soluble solder paste, W20. 

AIM’s W20 is a zero halide/halogen flux formula engineered for enhanced wetting performance on all solderable electronic surfaces. W20 exhibits excellent print characteristics and 8+ hours of stencil life. Its highly soluble residues are easily removed in plain water, even under low stand-off components. 

“This all-purpose water soluble product was created to meet the industry’s demand for a consistently reliable zero halogen water soluble solder paste,” said Timothy O’Neill, AIM’s Director of Product Development.  “Engineered to provide wetting, voiding and print performance equal to halide bearing water soluble pastes, W20 meets all current and future production and regulatory requirements of the EMS/Contract PCB assembly market.”
