Hi guys,

I was just chatting with someone on IRC, and he was missing footprints.

Apparently: 
http://www.geda.seul.org/wiki/geda:scg

Quotes:

SMT electrolytics are designated by can diameter in 1/10 mm: SME33,
SME43, SME53, SME66, SME84, SME104.


In PCB's geda.inc (since the dawn of CVS history), we have:

## Surface mount electrolytic capacitor, number is dia in mm
define(`PKG_SME3',      `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3', 33, 33)');
define(`PKG_SME4',      `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3', 43, 43)');
define(`PKG_SME4',      `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3', 53, 53)');
define(`PKG_SME6',      `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3', 66, 66)');
define(`PKG_SME8',      `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3', 84, 84)');
define(`PKG_SME10',     `PKG_SMT_2PAD_EIA(  `$1', `$2', `$3',104,104)');


Can someone check if this is right, then fix the Wiki page please?

Why do we quote SME6 for a 6.6mm package?
Is there a naming standard being followed?

Best regards,
