Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
WS488 is a water-soluble solder paste engineered for superior wetting on various electronic surfaces, components, and assemblies. It provides excellent print characteristics, extended stencil life (8+ hours), and robust environmental tolerance. WS488 is compatible with both leaded and lead-free alloys. Its residues are highly soluble and easily cleaned with plain water, making it a reliable choice for high-performance soldering applications.
