High-Reliability Lead-Free Soldering for Modern Electronics

ALPHA’s SAC305 Telecore HF-850 solder wire is a premium lead-free solution developed for high-performance soft soldering. With a halide-free, No Clean rosin-based flux (ROL0) and alloy composition of Sn96.5/Ag3.0/Cu0.5, this solder wire ensures excellent wetting, minimal flux spatter, and reliable solder joints across a wide range of electronic assemblies.

The flux core is specifically engineered to leave transparent, non-corrosive residues that meet the stringent J-STD-006B standard, eliminating the need for post-solder cleaning. It is ideal for applications demanding RoHS compliance and high process stability.
