The Loctite LF 318 solder paste is a halide-free, no clean, pin testable Pb-free solder paste, formulated to have excellent humidity resistance and a broad process window, both for reflow and printing. This product has a high tack force to resist component movement during high speed placement and long printer abandon times.

Good humidity resistance
Clear residues for easy post-reflow inspection.
Soft, non-stick, pin testable residues allow easy in-circuit testing
Extended open time and tack-life leading to low wastage
