Joy, don't get me wrong , just wonder : why off line ? Somehow i thought in the Net's spirit we wash tech. issues in open ? i'm actually using pad vias for leak through to smd connector legs on bottom side in one pass (dispense fill); they do have some use ; and those few design unavoidables are not that difficult to plug , still, would love to know what you do .

This design has through vias in the surface mount pads. Has anyone had experience with this situation? My first concern is losing solder through the via during reflow. Is there a good way to fill the via and still have a good solder joint? And what other kinds of problems can we expect? thanks for the help.
