Topic/Track: Assembly Processes for Lead Free and Tin Lead

Event Type: Technical Conference Session

In the switch to lead free, one of the unpleasant side effects of the use of higher temperatures in assembly has been pad cratering. This session brings in experts from assembly who will discuss tests to predict and diagnose pad cratering. If you have had a lead-free process "crater," then the information in this session is what you need!
