Frank,

The new IPC-TR-476A, released in May 1997, titled as Electrochemical 
Migration:  Electrically Induced Failures in Printed Wiring Assemblies, has 
described the difference between electrochemical migraion and conductive 
copper migration.  Another excellent reference will be Protonique SA 
on-line technical publication at http://www.protonique.com.
