• Fast wetting
• Light-colored non-tacky residue
• Reduced spatter formulation
• Works well for manual and robotic soldering processes
• Compatible with Pb-free and SnPb alloys
• Compatible with HASL, Immersion Silver, ENIG, and OSP surface finishes
• Good choice for legacy processes requiring an RMA strength product

CW-818 provides fast wetting speeds to minimize cycle times in manual and robotic soldering processes. This halide-free, no-clean formula leaves a clear, non-tacky residue even when using high tip temperatures. The heat resistant and low-spatter properties of this core flux provide an assembly with excellent visual appearance.

CW-818 Halide-Free, No-Clean Cored Solder Wire with Spatter Control Technology

Indium Corporation is quickly becoming known as one of the highest quality, full line suppliers of flux-cored wire solder. Indium Corporation uses only “conflict-free” and grade A (per ASTM B32) metals, as well as other high purity metals for its flux-cored wire. Our materials have been tested and certified to meet IPC J-STD-004B and other relevant industry specifications, including the legacy military specification QQ-S-571f. Indium Corporation’s flux-cored solder wire is well known for its:

• Void-free
• Evenly layer winding
• Low oxide shiny appearance over time
• Non-offensive odor for the 800 series and 200 series fluxes

CW-818 provides fast wetting speeds to minimize cycle times in manual and robotic soldering processes. This halide-free, no-clean formula leaves a clear, non-tacky residue even when using high tip temperatures. The heat resistant and low-spatter properties of this core flux provide an assembly with excellent visual appearance.

Indium Corporation specializes in making fine-diameter wire, typically between 0.004"" (0.1mm) and 0.015"" (0.381mm) diameter for robotic and laser soldering. To make robotic and laser soldering most effective and eliminate peaking and bridging, it is easiest to use an active flux such as CW-818 at 4.0–4.5% flux by weight.

All of Indium Corporation’s no-clean fluxes, including this formula, are designed to be electrically safe under normal consumer electronic and telecommunication operating conditions. Unless otherwise specified, electrically safe means that the post-soldering residues pass J-STD-004B SIR and ECM testing.

Indium Corporation’s cored wire solder has been designed to be fully compatible with our solder paste, wave fluxes, and rework fluxes, and is also expected to be compatible with many of our competitors’ products. For example, CW-818 flux-cored solder wire is not only compatible with Indium8.9HF Solder Paste, but also with our 5.2LS, 8.9 series, 92 series, and 10 series products.
