Product Overview

ALPHA EF-5601 contains over 30% less VOC’s than similar category alcohol fluxes making it much better for the environment and safer to use.

Benchmarked against ALPHA RF-800, an industry leading alcohol based flux, ALPHA EF-5601 complies with the industry's most stringent reliability requirements, while delivering excellent hole-fill and minimal soldering defects on most standard SnPb and Pb-Free  assemblies, including those with OSP pad finishes and prior reflows.

With its unique formulation, included solids remain completely in solution, resulting in consistent flux deposits, excellent post soldering cosmetics, and no clogging or buildup around fluxer spray nozzles. ALPHA EF-5601 is also pin testable.

Reduced VOC Flux with Alcohol-Like Performance

ALPHA EF-5601 is a resin/rosin containing, low-VOC, low solids, no-clean flux, which provides the highest activity of any low-VOC for defect-free soldering.

Formulated with a proprietary mixture of resin/rosin and organic activators, this flux delivers excellent wetting and topside hole fill, even with OSP coated bare copper boards.  

Several proprietary additives are also formulated into ALPHA EF-5601, which act to reduce the surface tension; thereby, dramatically reducing the tendency of solderball generation.
