SSOP20 package with body above is not correct. Corrected it for SSOP20, other SSOP packages might have this issue too. Also added a reflow version with rounded pads.

@wiebus @SchrodingersGat Can you please check this pull request?

@greenscreenflicker what was wrong with the old footprint?

greenscreenflicker commented 8 years ago

Old version has too small outline. SSOP needs some space above and below. The current footprint is TSSOP style without spaces,

Hi @greenscreenflicker

Sorry your pull request got forgotten for so long.

Since you submitted it, there have been changes to the footprints in Housings_SSOP.pretty. The current version of SSOP-20_4.4x6.5mm_Pitch0.65mm.kicad_mod looks like this ...

The body size is 4.4mm x 6.5mm, which matches this datasheet from NXP http://www.nxp.com/docs/en/package-information/SOT266-1.pdf, and the courtyard is 7.1mm tall, which is close to the value in the datasheet (7.3mm).

(Based on the files in the PR, I've assumed it was the SOT266 that you meant, and that "SOT226" in the PR title was a typo).

If this does not fix the problem you saw, and you are still interested in contributing, please open a new pull request (in synch with the current master branch) and check your contribution against the latest KiCad Library Convention here: https://github.com/KiCad/kicad-library/wiki/Kicad-Library-Convention.

Many thanks.
