Qualitek has developed several types of high-performance Delta Solder Paste designed for use in Sn/Pb or for Pb-Free circuit board assembly. Qualitek offers No-Clean, RMA (Rosin Mildly Activated), RA (Rosin Activated) and Water-Soluble solder paste types for surface mount assemblies. Delta Solder Paste types are available for printing, dispensing and package-on-package assembly. Delta Solder Paste is available in jars, syringes and Semco cartridges.| Product Brochure | Solder Paste Technical Data & SDS |
