SAC305 No Clean Solder Wire
4900 4917 Technical Data Sheet
ISO 9001:2008 Registered Quality System. Burlington, Ontario, CANADA SAI Global File: 004008 49004917
Description
The 49004917 SAC305 No Clean Solder Wire is an electronic grade solder wire.
It uses the predominant lead-free alloy composition and exceeds J-STD-006C and meets ASTM B 32 purity
specifications. It is complemented with a no clean, synthetically refined, splatter-proof resin flux core that
is classified as REL0 according to J-STD-004B. This solder is a great alternative to leaded solders.
The 49004917 solders achieve a consistent solder and flux percentage through a state-of-the-art,
extrusion, wire-drawing machine. This machine continually monitors the wire to prevent voids and ensure
consistency, providing a top-grade solder wire.

Flux Core Properties
The synthetically refined resin wets and spreads like a RA flux. This no clean flux is virtually non-
splattering. It gives rise to a hard, non-conductive, and non-corrosive residue.
