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是一種無鹵素、無清潔、低固體含量的液體助焊劑，專為波峰焊和手工焊工藝而設計。它可以與含鉛和無鉛合金一起使用。其**特性之一是能夠承受厚板組件所需的長時間**電池和高預熱溫度。焊劑中的持續活性可以在具有挑戰性的應用中實現良好的桶填充，例如回流銅OSP板或難以焊接的組件。NF372-TB殘留物最少，透明，不粘，適用于改良化妝品。根據IPC J-STD-004B，NF372-TB被歸類為ROL0通量。

NF372-TB焊劑是凱斯特高可靠性產品線的一部分，與NP505-HR焊膏、RF550返工焊劑和SELECT-10™選擇性焊劑兼容。
