SAC305 Lead Free Solder (No Clean)
4900–4917 Technical Data Sheet
4900–4917
Description
The 4900–4917
SAC305 Lead Free Solder (No Clean)
is an electronic grade solder wire.
It uses the predominant lead-free alloy composition and exceeds J-STD-006 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 4900–4917 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.

Storage
Protect from direct heat or sunlight. Store between 18 to 27 °C [65 to 80 °F].
Cleaning
The flux residue does not need to be removed for typical applications. If removal is desired, a solvent
system like the
MG 4140
can be used. For best results, warm the cleaning solution to about
40 °C [104 °F].
