Hi Jerry, I'm new to the group. Would you mind give detail dimensions on both 0603 and 0402. Thanks, Patrick Lam Phone:(604)293.4392 -----Original Message----- From: Galang, Jerry [mailto:[log in to unmask]] Sent: Tuesday, February 06, 2001 2:45 PM To: [log in to unmask] Subject: Re: [TN] Chip device vs pad sizes 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.
