How important is via position

[SaiTeja]

Hello,
I am designing NRF52832 based board. I followed the exact reference layout suggested by Nordic except via position. I moved few vias during routing. Is it necessary to follow exact via positioning?

Good grounding is key, but you don't need to place the vias exactly where we have done it in our reference designs. It is good practice to:

1. Place a via close to the ground pad of capacitors.
2. Focus on good grounding around the matching network and antenna.
3. Have as many vias connecting the upper and lower ground planes as you can. You can look at our reference designs to see approximately how much space you can have between them.
