Hi Guenter!

There's real good article about Black Pad that was presented at the 1999
Printed Circuits Expo thas has all kinds of good pictures. It's at:

Quite a while ago there was a discussion in TechNet about Black Pad. I read
some articles too, but what I am missing is a picture or two or so how
Black pad looks like ( sure it's more than just black ).

Have a great day
