Encapsulation is total immersion of a component in an organic material added for thermal, shock, humidity, security and/or ESD protection. Bev RIM -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas Pauls Sent: Thursday, June 04, 2009 2:32 PM To: [log in to unmask] 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.
