Hi Jerry,

I'm new to the group. Would you mind give detail dimensions on both 0603 and
0402.

Thanks,

Earl,
Not sure what went on last year. We us a pad with full radius ends for our
0603 and 0402 components. The rounded ends seem to pull the solder
perpendicular to the length of the component, very few 'tombstones' almost
no reports of end cap cracking, not bad for a million + boards a month.
What is our pad formula? If you design a 'standard rectangular pad' and
round the 'width' of the pad on both ends you have it.
