Hi All,

It seems like there is interest in microvia reliability.

I am sending out three microvia white papers to those that request them.


The papers do not tell the whole story on microvia reliability but it is
a good overview of the most influential factors affecting microvias, how
to test microvias and how they fail. 

These papers were presented at IPC, EIPC and appeared in various
publications.

Here is one of the two iconnect007 interviews on microvias I did with
Ray Rasmussen
http://www.pcb007.com/pages/zone.cgi?a=50577&artpg=1&topic=0

In responding to requests there will be no nice note in the reply emails
just the papers ... just the beef. 

I am planning to give a quiz after.


Sincerely, 
Paul Reid
