re: Circuit reliability: Old problem? New problem? Or both?

Well if one goes back to 1955 relability was sometimes measured in terms of a few hours of operation(tubes)    Now the best systems can get 40,000+ hours under temperature and vibration(Aircraft/Oilfield environment) -- In the 1970's I recall living with the frequent tube replacements on the TV which cost as much as a used car(tubes)

Now for high reliability one faces the challenge of reliability under thermal cycling.

Partly a device issue and partly a packaging issue (newer processes and lower cost devices and packages)

These are same old problems than can be used with existing tools. What can be improved comes from exploiting many-core GPU / CPUs, ease of use, data management and GUI. MP Divakar
