Jerry -
Let me follow-up on the answer provided by Robert, F5UL.
The Kester HQ is about 7 miles north of my QTH (recently moved from Des
Plaines, IL to Itasca, IL)
SN62PB36AG02
This number means the following:
SN62 - 62% Tin (Sn is Periodic Table designation for Tin)
PB36 - 36% Lead (Pb is Periodic Table designation for Lead)
AG02 - 2% Silver (Ag is Periodic Table designation for Silver)
While this is a "Silver Solder mixture" it is NOT the eutectic alloy mixture
The Melting temperature range (pasty state) is 354 - 372 degrees F ( 179 -
189 degrees C)
This is a WIDE melting range (18 degrees F or 10 degrees C) -- rick of cold
solder joints higher for technician with begineer-level skills.
Diameter: .015" is self explanatory.
This size is usually used for
Kester Part Number: 14-7150
This is VERY REVEALING.
The "14" is usually reserved for 1 LB rolls of SOLDER WIRE that has NO FLUX

CONTACT Kester (or their catalog for this part number) -- for clarification
and confirmaiton.
SOLID SODLER WIRE (with NO FLUX) IS NOT APPROPRIATE FOR ELECTRONCI KIT
CONSTRUCTION (Elecraft or anyone else).
What you WANT is a FLUX-CORED solder wire.

I would ONLY used a Kester "44" ROSIN FLUX products (highly active RA).
UPC numbers can be found on this web page for various offerings of the "44"
Rosin Flux series
http://www.kester.com/en-us/products/prodcat_detail.aspx?pid=43
1 LB Rolls
UPC: 24-6337-0007 0.015 diameter 63 / 37 - core size 66 *Euctectic*
UPC: 24-6337-0010 0.020 diameter 63 / 37 - core size 66 core *Eutectic*
ON MY WORKBENCH
UPC: 24-6040-0010 0.020 diameter 60 / 40 - core size 66 core
Rosin "44"® is a high activity RA core flux designed for excellent instant
wetting action, even on Nickel surfaces. Although "44"® is a RA-based
material, the residues are non-corrosive if not cleaned. Per J-STD-004, "44"®
is classified as ROM1 flux.
The "44" designation is obviously shown (yellow/gold label common) on every
1 pound role that Kester produces of it.

Kester does have a very good web site for reference mateirals on their
products.
