ALPHA EF-8000 lead-free no-clean wave solder flux claims to provide excellent first pass yields, worry-free in-circuit testability and excellent electrical reliability in lead-free and tin/lead wave soldering applications.  IPC rated ROL0, exceeds the Bellcore and JIS standards for electromigration and surface insulation resistance, as well as more stringent electromigration and bulk insulation resistance requirements from leading OEMs. 

"ALPHA EF-8000 flux creates a new industry standard for broad latitude application, because it withstands the higher PWB surface temperatures required for successful lead-free soldering, but it is fully capable for use in standard tin-lead applications," said Mitch Holtzer, global product manager.  "In addition, it can be qualified now for emerging lead-free requirements, and used in lead-free or tin lead production lines." 

Low rosin content minimizes flux residue buildup on pallets and wave soldering equipment normally associated with high (>10%) rosin flux formulas.
