GC3W is a halogen free, water-washable, Pb-free solder paste specially formulated to provide excellent humidity resistance. GC3W shows excellent solderability when reflowed in both air and nitrogen across a wide range of challenging surface finishes including OSP-Cu, ENIG and Silver.

Room Temperature Stable to Eliminate Cold Storage.

This temperature stability solder paste provides exceptional results in aqueous cleaning systems without the addition of saponifiers or co-solvents. Post-reflow residue removal is fast and easy, and the cleaning window has dramatically expanded, allowing manufacturers the flexibility to clean boards seven days after assembly. Stencil life and abandon times are superior to previous‑generation water wash formulas and storage stability is extended to provide game-changing, water-washable performance.
