Hi SW-M/W David, IPC LF Listservers,
<The suggestion is that basic materials reviews should be part of any pre-
use analysis (plus FEMA or MIL-HDBK-217 or other basic reliability
approaches) rather than just ask suppliers to certify regarding performance
as they may not know all their operating parameters at high temp. for both
the mechanical and microwave performance. We were at the European
Microwave Symposium (Paris) last week and this was a common discussion
topic wherein we often-noticed a lack of materials background involved in
analyzing the "whys" involved.>
I agree.
Most are not looking at degradation in elecrical/electronic/microwave/
peformance. Physical and Process sustainability, repeatability, and
reliability as a dark horse are coming first. Oh Well!!, yet I think that
this is the way major technology disruptions roll out.
Yours in Engineering, Dave
