Kester NF372-TB is a low solids alcohol based flux designed for both standard and thicker, high-density PCB's. A leading feature is its ability to withstand long dwell times and higher solder pot temperatures needed in thick board assemblies. NF372-TB delivers sustained activity within the flux 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, and can be used with both leaded and lead-free PCB's.
