NF372-TB Soldering Flux


Kester NF372-TB is a zero-halogen, no-clean, low solids liquid flux designed to be used in wave and hand solder processes. It can be used with both leaded and lead-free alloys. One of its best features is the ability to withstand long dwell times and high preheat temperatures needed in thick board assemblies. Sustained activity within the flux allows for good barrel fill in challenging applications, such as reflowed copper OSP boards or with difficult to solder components. NF372-TB residues are minimal, clear and non-tacky for improved cosmetics. NF372-TB is classified as ROL0 flux under IPC J-STD-004B.

NF372-TB Solder Flux is part of Kester’s high reliability product line and compatible with NP505-HR Solder Paste, RF550 Rework Flux and SELECT-10™ Selective Soldering Flux.
