Sorry on N2 and tombstone, many other aspects cause tombstones and n2 in itself does not cause tombstones. It can help make other bad variables tip over edge to cause tombstones more than with no N2. Get these right then N2 is not issue.

Are parts always following the same side/direction of tombstone? 1. Run 180 and observe if tombstone moves or remains the same 2. Too much paste under the part - reduce aperture and move it out to the lead. 3. Soak profile for even heat distribution

I would like to know what you are seeing in production. I have read the papers that state fewer tombstones with SAC305 as well as the papers that state more tombstones with SAC305. I am seeing more tombstones with SAC305. I place a lot of 0402 com

Kris The majority of our tombstoning in very small passive SMT is caused by imperfections in end-cap solderability protection plating.
