Hann,
Help me out here. By underfill do you mean an application of an RTV or is
it some other process?

Subject: [TN] Query: industry standard for pretreating PWB/PCB before
underfilling?
Hi
Can someone help me with the question?? Thank you very much.
I'm posting the above question as a technical marketer for 3M. We're
currently working on underfills and the question is posed in consideration
of the outgassing of the PCBs.
If there is'nt a standard, then the next question is; typically, what are
the pretreating conditions if there is any pretreating at all?
Thanks and regards,
Hann Pang
Technical Markerter
