Hi folks,

We have some great contributions here prepared by Michal Stec. He's
generating SMD packages appropriate for the convention, however we were
unsure how to make the silkscreen for QFN packages. If it's done the same
as TQFP, it yields, for the pin one indication, a bar so short it's going
to be difficult to see. We thus tried to find something else. Please have a
look at the two screenshots below. The first one has a more visible mark,
but I'm unsure if there are QFN packages with pins in the reverse order, in
which case we can't tell from the silkscreen. Any comments? I have attached
the file.

Regards,

Carl

 This one looks ok.
I looked at my msp430 programmer, and I saw that they've done sth like that
below. I think it was good, so if you agree I will make this one.

Oops, I didn't notice I exceeded courtyard.

 How about this? I'm trying to find a way to have a clear marking, not a
line 0.4mm long.
