High Reliability Liquid Fluxes

A broad line of water soluble and no-clean liquid fluxes that provide excellent resistance to electrochemical migration.

Leading High Reliability Fluxes

PRODUCT NAME	DESCRIPTION	KEY FEATURES
ALPHA EF-6103	A high performing low solid, no-clean alcohol based flux, designed with combinations of activators and solvents. It is effective in cleaning all the surfaces, especially on reflowed OSP during wave or selective soldering.	Pin testable Compatible flux chemistry for both wave and selective soldering Excellent lead-free soldering performance on various board finishes
ALPHA EF-6808HF	A halogen-free, low solids, alcohol based, no-clean flux for use in a variety of automated and manual soldering applications. While effective on many types of assemblies, this flux has been found to exhibit excellent hole fill on assemblies with high-density components.	Halogen-Free Broad spectrum liquid flux for general wave soldering application Excellent soldering performance with good hole-fill and low bridging on high density assemblies
Kester NF372-TB	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.	Zero-halogen Suitable for longer soak (> 5 seconds) in high preheat (>125°C) and high solder pot temperature processes Excellent hole fill demonstrated even on board thickness > 3.0mm
ALPHA EF-8800HF	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.	Halogen-free Wide process window Robust soldering performance under high top-side preheat (>125⁰C), high pot temperatures (>270⁰C) and long dwell times (>7 seconds)
Kester Select-10	A zero-halogen, high-reliability, no-clean flux for improved performance in selective soldering applications. Sustained activity within Kester SELECT-10 allows for good barrel fill in challenging applications, such as reflowed copper OSP boards or high preheating temperature over 135°C.	Zero-halogen Excellent for selective soldering Controlled flux spread within localized flux spray pattern
Kester NF1060-VF	A zero-halogen, VOC-free wave soldering flux with several proprietary additives to reduce the surface tension to enhance the wetting properties, providing desired hole-fill and reduced common soldering defects seen in VOC-free fluxes.	Zero-halogen VOC-free for lower VOC emissions Exceptional wetting for excellent hole-fill, even with prior reflows
