Hi Jack, That workshop was in 2007; that is at east 2 versions of the White Paper ago. I am continuously updating the White Paper and am now shipping v.09 which is almost double in content from v.07. Even then, there was more in the White Paper than I can put into a 3-hour workshop without overloading the audience.

I took your workshop at IPC MidWest called "How to Specify PCBs to Reliably Survive the RoHS-Mandated Lead-Free Soldering Processes" which was VERY informative (you are a good teacher). but I would like to know if there are topics or data in the White Paper that aren't in the workshop? surfin' the learnin' curve, Jack .
