Hello all,

Is anyone out there stencil printing SMD adhesive to
populate 0603 parts?  I would be interested in hearing of
your experiences.

 The way I have it calculated is that I have 0.020" between
pads.  With a 0.010" aperture I have a whole (dripping
sarcasm) +/- 0.005 to play with.  I don't know...but when
you take into account stencil alignment accuracy and
adhesive squeeze out after the part is placed, this just
doesn't seem destined to become a six-sigma operation.

I realize a smaller aperture would help, but I am already
concerned with how consistently the adhesive will be removed
from the apertures during clean-up.

 Thanks,
Gary Camac
