We've been wave-soldering MELF and SOD80/SOD87 pkgs in large qty's
for about 5 years now.  We've had little problem with alignment, using
square pads.  The biggest problem we've had is bridging - mostly due
to board density being much higher than ideal.  (By large qty, I mean
over 1 million units/yr, with about 8 diodes per unit)
