I would like to add a comment on removing solder from SMT via
holes. There are three methods and the first two have been
discussed. I have found as the technology gets better, smaller, the
plated through holes also get really small. Like 0.020 or
smaller. Solder suckers have a very difficult time pulling the solder
up.
There is no need to remove solder from SMT via holes. It's only
necessary for the holes used by through-hole components.
