There might be a way to save these boards:

Retrofit the wave with an Omega wave ( to vibrate the solder; available from
Electrovert). Turn the vibrating pump up to 55%-65% when soldering these
boards. You will be amazed how much higher solder can wick when its surface
energy is broken down. Good thing is you don't have to increase the preheat
or prolong the dwell time, risking the board warpage and flux overcooked.

Regards and good luck,
