Remember that solder under the chip's edge after placement is shadowed so it heats up slower and can result in an "island" of solder that pools up on the solder mask if the unshadowed solder melts quickly and pulls away. Make sure your screen apertures are designed so that when the paste is squeezed down, shadowed solder is minimized. Also, make sure the screen bottom is super cleaned between applications.
