Exactly! More complications for the problem.

Additional problem: how many leads ? from co-planarity table: Min stencil thickness doubles just to reach bottom of lead from .004 for 5-10 leads to .008 mil for 25-36 leads. This is before you have enough paste to create the large fillet.

See: http://www.samtec.com/documents/webfiles/cpdf/TSM-1XX-XX-XX-DV-S-XXX-XX-MKT1.pdf Is this considered a gull wing for J-STD-001 solder joint requirements? At .63 mm square, this is a relatively thick lead that requires a lot of solder to get a heel fillet to the top of the lead (class 3 solder joint). I realize that there are several ways to add solder (overprint, dispense, preforms, etc.), but I don't want to go down those paths if I'm not working to the right requirement.
