Many of today’s printed circuit boards have both through-hole and surface mount components. Selective soldering methods vary in cost and effectiveness, depending on the number of through-hole components, secondary side components, and many other factors. I was very impressed with the automated selective solder process at QPL Electronics Manufacturing Services in Hillsboro, OR. This process is most cost effective if a board has 100 or fewer through-hole pins. This process is especially effective for extra heavy leads, like on a terminal block. Wave soldering often requires rework on these pins while the automated selective soldering system provides control of the soldering duration and depth for each contact. Here is a video of their automated selective solder system in action.
