? If I use smallest pattern 0402 it calculates out to about .56mm sq pads on .84mm centers. The 1mm BGA works reasonably well with this size 0402 and with gaps in balls on the

(especially when using lead-free solder). Here are my recommendations for the largest 0402 (1005) chip capacitor land pattern and it's in the IPC-7351 Nominal environment

... Ideally I would like to just have one 0402 cap footprint and one 0402 res footprint in the layout, but it would also be possible to have two of each, wuth a special one for under the BGA
