. Test Vehicle The solder paste printing process was performed at a DEK265 series stencil printer. A 4-mil thick laser-cut electro-polished stencil was used

causing solder protrusion. 2. When the solder goes into the vias, it robs the thermal pad from having the optimal solder joint. Less solder = bad connection. 3. The thinner PCB thickness of 1 mm can be problematic because it's easier for the solder to flow out the bottom side and could cause shorting

0.25 mm spacing between paste mask apertures. I see some designers overlap the thermal tab paste mask with the signal pin paste mask and that stencil will not work

. Let's say you use a 0.125 mm (5 mil) stencil thickness. If you have a thermal pad that has 100% paste mask coverage, there is no where for the solder to flow and the package ends up sitting on top of
