Good Morning SI-List!
This topic and concern came up in regards to GHz signal routing, but I have not
found any references in published literature. If there are combinations of PCB
materials, via dimensions, design parameters, assembly processes and
environmental usage conditions that can manifest a reliability concern I'd like
to understand these issues and failure mechanisms, but I don't want to chase
these ghosts and over constrain ourselves if none have been
seen...................
Perhaps this was a problem once upon a time and has been overcome by ongoing
technical progress and process improvements?
Thanks for any insights, technical references, history lessons or relevant
experience you may be able to share with us.
Regards,
John
