WF-9948 is a fourth generation high-performance no-clean wave solder flux designed for use with through-hole and mixed-technology assemblies. While only containing about 3.3% flux solids, WF-9948 is very heat stable and well-suited for selective soldering applications. It performs well with both tin-lead and lead-free solders.

WF-9948 has been designed to pass all known reliability requirements, including J-STD-004B SIR and ECM. This modern flux is non-corrosive, compatible with probe testing, compatible with most conformal coatings, and does not contribute to detrimental circuit board insulation resistance degradation or electrochemical migration.

• Passes J-STD-004B SIR and ECM requirements for ROL0
• Indium Corporation created WF-9948 by adapting Indium’s very popular WF-9940 flux to the J-STD-004B requirements
• Fast wetting halogen-free formulation
• Wide process window for soldering larger and/or thick circuit boards
• More heat stable than rosin-free formulations
• 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
• Compatible with all spray fluxes
