I'm trying to figure out how I'm supposed to get traces to the four internal data pins of the Wolfson WM7230 Digital Microphone part.
It's got a ground ring that is supposed to have a tight solder seal. You can see from the datasheet recommended PCB pattern, that the four internal pads are completely surrounded by the copper ground ring.
I thought it was bad news to put vias in the pads themselves. This thing is a pretty small part; is the intention that I put via's immediately next to the pads?
Tried to find some example layouts with Google, but no luck.
