Indium 84191-GAL – NC-771 Pb-Free No-Clean Flux (1 Gallon)

• Quantity: 1 gallon
• NC-771 is an alcohol-based, rosin-free, no-clean flux in an applicator pen
• Passes SIR test in the un-reflowed state
• Halogen-free
• Backwards compatible with eutectic SnPb 

NC-771 is a halogen-free, low-residue, all-purpose liquid flux that passes the SIR test in the un-reflowed state. It can be used in a standard SnPb or Pb-free rework or soldering process. In addition to the aesthetic benefits, the ultra-low post-reflow residue is non-tacky and will not interfere with probe testing.

Process Recommendations

NC-771 is a multi-purpose flux that can be used in an SMT rework process or almost any soldering application that requires the addition of a liquid flux. Typical application methods include a flux pen that allows you to apply a precise amount of flux to the solder joint. It can also be sprayed on for use in a selective soldering process or dispensed from a flux bottle. Care should be taken not to flood the solder joint and to apply the flux only to areas that will be exposed to complete heating from the solder iron or rework tool.

NC-771 is designed for no-clean applications; however, the flux can be removed, if necessary, by using a commercially available flux remover.
