0402 components | 24 February, 2000

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.

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).
