Solder paste can be dispensed quite well from these systems provided that
proper attention is paid to correctly specifying the material. Solder pastes
are inherently more difficult to dispense than adhesives but if particle
size range [and distribution in the specified range] is correctly done with
the right vehicle rheology, consistent dispense at quite high rates is
achievable.

Hi, Craig,
You could try Asymtek, part of the Nordsen group, which specialises in
fluid dispensing technology. They seem to be the market leaders. They do
underfill, adhesive and flux dispensers, and though I haven't seen a solder
paste dispenser in their list, they may do one. Or try EFD - they do have
a paste dispenser, but you'll need to decide its accuracy for yourself.

Hello Technetters,
For research and development purposes, I am looking for a machine that
dispenses solder
onto a board WITHOUT the use of a solder stencil. The speed is not as
important as accuracy and
quality of work.
Do you know of a machine like this? If so, how can I find one?
Thanks for your help,
Craig
