I extended the pads to help ensure the component locates correctly and to allow for easier re-work should problems occur. I reduced the thermal by 5% but you may want to speak to your fabricator and ask what they require to ensure that the resist is

Hi Evtimov, Thanks again! The solder wicking/open solder joint is not actually gross rejection, it is only a few and appeared random (difficult to trend the location of the opens), what is perflexing is that i have this 1 or 2 open solder joints sur
