Kester NF372-TB is a zero-halogen, no-clean, low solids liquid flux designed to be used in wave and hand soldering processes. It can be used with both leaded and lead-free alloys. One of its best features is the ability to withstand long **ell 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.

Kester NF372-TB是一种无卤素、无清洁、低固体含量的液体助焊剂，专为波峰焊和手工焊工艺而设计。它可以与含铅和无铅合金一起使用。其**特性之一是能够承受厚板组件所需的长时间**电池和高预热温度。焊剂中的持续活性可以在具有挑战性的应用中实现良好的桶填充，例如回流铜OSP板或难以焊接的组件。NF372-TB残留物最少，透明，不粘，适用于改良化妆品。根据IPC J-STD-004B，NF372-TB被归类为ROL0通量。

NF372-TB焊剂是凯斯特高可靠性产品线的一部分，与NP505-HR焊膏、RF550返工焊剂和SELECT-10™选择性焊剂兼容。
