I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

It's normal for us when we review design. We have found that in the Y axis we need .015" whereas in the X axis we can use .005" spacing. this relates to our nozzle size vs. pickup skew etc... This wouldn't apply if there are parts taller than XXX

We have never dispensed adhesive for 0402, but here's your rules of thumb: * Nozzle diameter should be half the desired glue dot diameter. * Minimum of 0.010" gap between the adhesive and pad, both sides. We'd guess that you should be using a 0.3mm

Mark, This topic has been discussed multiple time on this site. You can find almost all of them by searching the archives for tombstoning. That aside, have you look at your stencil apetures?(homeplate design).
