ALPHA EF-6100P
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- Broad Lead-Free Process Window
- Reduced Bridging and Solder Balls
- Low-Residue Pin-Test Surface
Product Description
ALPHA EF-6100P Liquid Soldering Flux is a low-solids, alcohol-based no-clean flux for wave and selective soldering with lead-free and tin-lead alloys. It is designed for assemblies that require strong through-hole fill, reduced component bridging, and fewer skips. Thermally stable activators support a broad process window, while the formulation resists solder-ball formation across a range of solder masks. Residue is low, non-tacky, and designed to minimize interference with pin testing. Spray application is specified, with separate process ranges for SAC305 or SACX0307 and 63Sn37Pb operation. Typical as-supplied data include 3.8% solids, 0.794 +/- 0.003 specific gravity at 25 deg C, and ORL0 classification.
Key Features
- Broad soldering window: Thermally stable activators support lead-free and tin-lead wave soldering.
- Reduced solder defects: Designed for strong through-hole fill with reduced bridging, skips, and solder-ball formation.
- Pin-testable low residue: Very low, non-tacky residue minimizes interference with pin testing.
Applications
Spray-applied wave and selective soldering for lead-free and tin-lead circuit-board assemblies.
