Subject: [TN] Coating, Encapsulation, and Potting
Good afternoon all,
All this talk of underfill sparked a reminder of an IPC action item of
mine. Unknownst to most of you , I signed you all up on some of my
committees. There will be a new task group addressing potting and
encapsulation, which will meet at the Fall IPC. We already have conformal
coat task groups.
So, I wish to initiate a series of questions and illuminating debate.
Pardon me if I fall short on the illumination part (leave it alone Dewey).
1. What would you consider to be a definition of "potting" and a
definition of "encapsulation"?
2. Are there standard definitions for these somewhere? They don't exist
in IPC as far as I know.
3. What would you consider to be the boundary between conformal coating
and "potting or encapsulation"? I have my own opinions but want to hear
yours.
4. In what class would you consider an underfill to be in?
That's enough homework for now.
