Sn63/Pb37 Leaded Solder
488x (x
= 0, 4, 5, 6, 7, 8)
Technical Data Sheet
488x-series
Description
The 488x [where x =0, 4, 5, 6, 7, 8] series of
Sn63/Pb37 Leaded Solder
is an electronic grade solder wire.
It uses the eutectic tin-to-lead alloy ratio, which is complemented with a RA-like flux core. The 488x series
generally exceeds J-STD-004 and J-STD-006 specifications. It is one of the easiest solders to work with
because it offers a low-melting temperature with a sharp melting/solidification point, which results in
robust and reliable joints that are highly resistant to whisker formation.
The 488x leaded 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.

Because this product contains lead, it is not RoHS
compliant. The following RoHS exemptions are
applicable 7(b), 15, 24, 31, 33.
a) Meets the requirements of J-STD-006
Storage
Protect from direct heat or sunlight.
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].
Health and Safety
Please see the 488x (where x = 0, 4, 5, 6, 7, 8)
Safety Data Sheet
(SDS) for more details on
transportation, storage, handling and other security guidelines.
