I'm looking for a guideline or resource (IPC spec?) on how to select and
specify the proper Tg for a given design? I'm not talking about process
wise (Tg140 is acceptable in our lead-free processes), but design wise.
For example, is Tg140 material sufficient for a board running 80amps
through it and sitting in an enclosure on a hot summer day in Arizona?
Also, I'm looking for how best to test the Tg robustness during
production. Any help would be greatly appreciated.
