We solved similar problems some time ago. Check the volume dispensed or printed. Also check that the glue or solder paste has not expired and if in doubt use a new cartridge or change supplier. Ensure the Z axis stroke and placement force is corre

We have never dispensed adhesive for 0402, but here's your rules of thumb: * Nozzle diameter should be half the desired glue dot diameter. * Minimum of 0.010" gap between the adhesive and pad, both sides. We'd guess that you should be using a 0.3mm

You can order the glue stencil at http://www.usastencils.com They can design the opening of the apertures on the stencil in the middle of the caps so you can screen an adhesives through the opening then you will have it right on the center of the cap

if you wave solder you have to glue the SMD parts on the bottom side. If you reflow the bottom side then you usually shouln't go over the wave afterwards. It's quite logical the joints melt again, that's what you want to achieve going over the wave.

The first reply from Tsvetan Usunov already answered your question - there are no thermals for one side of the chips. You can try to reduce the phenomenon by using different solder pastes, tuning your soldering profile or even switching to different
