ALPHA EF-6000 rosin-free wave solder flux is designed for lead-free and tin-lead processes. The alcohol-based, no-clean flux reportedly provides superior solderability and high yields as processes are transitioned from tin-lead to lead-free.
 
Offers in-circuit pintestability and electrical reliability in tin-lead and lead-free wave soldering applications.  IPC rated ROL0, exceeds the Bellcore and JIS standards for electromigration and surface insulation resistance.
