This sounds like you are using a straight ramp profile. For this type of an assembly you may need to use a soak type profile. Most solder paste providers show you both types of profiles that work best with that paste. I would try using that profil

Also try boosting the bottom zones up to get extra heat in. Now try this at lead free temperatures & watch them go pop as the air inside expands & vents at the base. O to be in America & be free of our wonderful european decision makers.

I would use a spot solder machine. If not, why not spray the mask onto the board? Use a Camalot machine or something similar. Using a stencil over placed components wil yield a thick mask - right? That's why I'd spray.

I believe DEK manufactures stencils that will do this. I'm sure their Apps. engineers could help you with squeegee material etc. good luck, pr
