In a former life, I used Alpha Metals WS-609, 90% metal and flux activity
ORH0.  Dependent on your throughput, the only drawbacks are a 4 hour stencil
life and 6 hour tack time.  A typical reflow profile is recommended with
time above liquidus to be 45 - 75 seconds.  The flux residue can be easily
removed with 140°F water (w/o saponification) in a timely manner.
This paste formulation has been around for quite awhile.  With that said,
there are probably other formulations that are available but I don't have
any personal experience with them as I have gone backwards in my career and
have been somewhat forced to use a RMA formulation.
Good luck with your search.

Subject: [TN] solder paste


Hello Technet...  My solder paste manufacturer, who shall remain nameless,
is discontinuing our presently used water soluble paste, so I'm looking for
a replacement.  What seems to be the most widely used water soluble Sn63
solder paste these days?
