We are having issues with 0603 components attached with glue (Glue printed with Pump printing) that are being fallen in the wave soldering equipment. The average dot size that we are having in these components is 0.025" and the average torque value is 1 N-cm. What could be possible causes for this issue?

Dot diameter for 0603's is nominally 20 mils. Dot diameter for 0805's is nominally 28 mils.

This stencil is developed by DEK but I'm not too sure of how it works? Any experiences? Also would be too kind if somebody could tell me the glue size requirement for 0603 and 0805 components?
