ALPHA EF-6000 is an active, rosin-free, low solid, low residue no-clean flux.  With a wide thermal process window, it delivers good hole-fill across different preheating temperatures and dwell times.  

Several proprietary additives are formulated into ALPHA EF-6000 to reduce the surface tension between the solder mask and the solder; thereby, dramatically reducing the tendency of solder ball generation. The formulation of ALPHA EF-6000 is also more thermally stable, for lower occurrence of solder bridging during dual wave soldering.

ALPHA EF-6000 has been designed for lower resistant residues to minimize the impact to electrical frequencies by no-clean flux residues. The minimal residues also offer better pin testability and cosmetic appearance. 

Product Features

Low Residue Low Solid No-clean Flux

ALPHA EF-6000 is a rosin-free, no-clean, alcohol-based, fully lead-free capable ORL0 flux. It delivers broad process compatibility and excellent first pass yield. With minimal flux residues, no false failures during in-line pin testing is observed and no post cleaning on-board is required versus classic rosin-bearing fluxes.

Same benefits apply for extremely low equipment maintenance.  With special proprietary flux activator system, ALPHA EF-6000 offers high reliability, passing SIR IPC J-STD-004 for long term reliability.
