ALPHA EF-6100P

Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium

ALPHA EF-6100P

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.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
