William,

Besides the usual suspects (Loctite, Heraeus, etc), you might try MA-420
from Thermoset (http://www.thermoset.com). Seems to meet your
requirements.

Regards,
Peter

Subject: [TN] SMT adhesive


Hi All,

I am looking for an SMT adhesive with the following characteristics:

1.      1 part
2.      Dispensible
3.      Thermal (not sure of a number here)
4.      Snap cure (re-flow)
5.      Re-workable
6.      Extended work life (prefer several days)
7.      Will not lift parts during cure in re-flow oven)

Please tell me I'm not asking for much.  We are presently using LocTite
3615
which dispenses great, but happens not to be a "thermal" adhesive and is
not
reworkable.  And, unfortunately, we have not matured enough to learn
from
our mistakes and get rid of re-work.  Or even keep it to a minimum, but
that
is a story in itself.

I would like to "stick" with a large company with plenty of resources,
e.g.
LocTite.  Any reccommendations?

Thanks for any info you can give,

Bill Mengers
