WF-9942 is a highly active no-clean wave solder flux designed for use with through-hole and mixed technology assemblies.

Product Information

WF-9942 is a highly active no-clean wave solder flux designed for use with through-hole and mixed technology assemblies. It has been effectively used in both tin-lead and lead-free soldering operations.WF-9942 is a second generation no-clean flux designed to meet the requirements of J-STD-004. Although not specifically designed for lead-free soldering (third generation no-clean) or to the requirements of the later J-STD-004B (fourth generation no-clean), 9942 has been successfully and reliably used to assemble millions of circuit boards for the last 15 years. WF-9942 exhibits very good SIR and ECM results when tested to the J-STD-004 and Telcordia GR-78 requirements.

Features

  • Passes J-STD-004 SIR and ECM requirements for ORL0 and passes Telcordia GR-78 SIR requirements
  • Very low solder balling
  • Wide process window for soldering larger and/or thick circuit boards
  • Can be applied by foam or spray fluxing
  • Tested for use with all common lead-free and tin-lead alloys, including SAC305, SAC105, SAC0307, silver-free tin-copper plus additive alloys, such as Indium Corporation’s Sn995, 96.5Sn/3.5Ag, 63Sn/37Pb, 60Sn/40Pb, and many others
  • Tested compatibility with Hot Air Leveled (HASL), Immersion Silver, Electroless Nickel Immersion Gold (ENIG), and Organically Solder Preserved (OSP) Copper Surfaces
  • Rosin-free for enhanced pin probe testability

Physical Properties

WF-9942 is almost colorless indicating that it is rosin-free. The solvent blend ensures even distribution of flux solids both during storage and during spray flux deposition. The specific gravity of WF-9942, 0.828 @ 25°C, is measurably higher than that of pure isopropyl alcohol. However, in contrast to higher solids content fluxes, specific gravity is not the best method to control the quality of WF-9942. This is because flux solids content is relatively low and small amounts of water contamination can confuse specific gravity measurements. While in-process quality control of WF-9942 is not generally required, the best method is to ensure both solids content and activity level, is by acid value titration.
