Craig,

Camelot or Asymtek dispensers will perform the generic task that you desire,
but you might also speak with your solder paste supplier for a paste
specially set up for dispensing.

Past experience was that I used a 86-88% solids paste to prevent jamming, or
clogging of the needle.  Also used the EFD tapered needle.

Less than 25 mil pitch (~0.6mm) became a real hassle, because the needle
diameter had to be quite large to prevent clogging

From a lab type standpoint, it is certainly 'do-able'

Subject: [TN] Looking for a "special" solder paste dispenser


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
