(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

& .8mm pitch BGAs on it. Using 0402 caps on back. Question, does anyone have any input with problems etc using 0402 patterns created using the smallest pattern calculated with current calculator
