Aloha Sonia,
I'm glad you found this interesting.
Please consided contacting David Aylward , davida@dsnplus, is the designer council
president on my list from IPC ,in the San Jose area .
Rick Hartley's e-mail is [log in to unmask]
He presentation is very well presented in layman terms for designers it also
contains excellent practices for engineer's - issues not taught in college.
If you can get him in town, I highly recommend the designers council plan an event
around him.
Aloha Ray
