Just a basic suggestion.... Inspect the nozzle placing the component...because that is the only medium, apart from the PCB design, which can be causing the damage. It occurred in my Department.

Use multiple small stencil openings [15 thou square], where total area approximately 50% of total PCB ground pad. What's the problem?

The solder adheres to the lands very well so i don't think that problem is with solderability of the PCB. Not wetting to the 0805 terminations. When the problem appeared with the 0805 we chenged the supplier. But there was commnon element Pb-free te

I agree with the stand alone option. That way you can sample PCB's from different stages ( print, placement post reflow) In a controled process, after reflow inspection would be ideal.

There are some basic suggestions given by everyone that cover most of the requirements. However, I would also like to point out your mention of using a fixture to hold PCB. Are you profiling the board with the fixture? If not, this could be one of th

Assembling boards with 12 pitch are very difficult to control. We like flat surfaces on boards with components below 25 pitch.

You may to reduce a little bit more with HASL. for .4mm pitch and such I would maybe go to a 5 mil with your standards.
