Adeline,
I have done a good deal of keyboards. You'll need to know if these keypads
will be gold plated or carbon ink. The widths and types of patterns can
depend on this. They tend to need wider traces when carbon ink. The carbon
ink has been widely used for me, it is plenty durable and cheaper than gold.
It's been about 2 years since I've done one, but I don't think the
technology has progressed so much that my patterns are un-acceptable. Maybe
you'll get more advise on this forum, but if not you can contact me off line
if you'd like me to send you them.

Subject: [PEDA] footprint for key-finger/keypad


Hi,

I'm going to start a layout with key-pad but I can't find any recommend
footprint for it?

Any advice or help on this?

Thanks!
Ciao...
Adeline
