Depending on the volume of boards you are manufacturing, the most cost effective solution would be to epoxy plug the vias prior to LPI soldermask application. The technique is common practice and most suppliers can provide it will little or no cost a

We are using selective soldering pallet, which the soldering flux is Interflux 2005M. We encountered the poor hole fill mainly at the heat sink components. Initially we tried to apply more heat but tend to overkill the flux activity. After some modif

Using common wire size and through hole diameter, we'd expect that the wave solder process would completely fill the through hole and that you wouldn't need to get involved in providing stencil openings, pasting the through hole or reflowing the jump
