Product Overview

Kester NF372-TB is a low solid alcohol based flux designed for both standard and thicker, high-density PCBs. 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.

Kester NF372-TB residues are minimal, clear and non-tacky for improved cosmetics.
