Thanks for the valueable feedback, I have two questions 1. why do you have to extend the pad size ? is it okay if i keep pad size 2. I am currently using thermal pad size recommended in datasheet max value 4.2mm x 4.2mm, how much should i shrink

First, the reflow thermal recipe provided by your paste supplier is only a ball park guess. Beyond that, the temperature measured by thermocouples on your oven heaters are only loosely related the temperature of solder paste on your board. You need t

Thermal pads located underneath leadless devices require a 50% reduction in the stencil aperture.

Thanks A.J. knew about the thermal pad reduction but not the overprint. off to CAD!

We have seen that vias included in the PCB under the thermal pad will give less voiding.
