EMC and EMI concerns

Looking at this again, it seems that the via-in-pad holes go all the way through the PCB, so maybe the module has a GND plane internally and all of this is fine already.

Thanks for taking the time to help me, it's greatly appreciated.

I will contact InsightSIP again to try to get a more certain answer. (just to be safe)

thank you, I also looked at the same gerbers and I thought they have 2 or 3 GND pours under the pads.

They also seem to use a via that does not go through the whole board. I'm not sure from these gerbers if its a 4 or 6 layer board. I never normally try to read gerber files so maybe I've made a mistake.

I reached out to their contact page for support but I've not received a reply.

Hi Jason,

as far as I can see they don't have any ground between the bads in their reference design/DK:

Gerber files, DK

So what you have done looks okay, based on their reference.
