Hi Mike,
That was a great reply by Phil, and I will certainly be using what Phil has
said to strengthen my case as I too am going through exactly the same
scenario as you Mike.
I have recently written a report (using JEDEC-033) outlining the main issues
with MSD, the consequences and actions that need to be taken. The report has
a particular emphasis on BGA's as we can "actually prove" that moisture
ingress through bad storage practice effects this particular component. As
you have mentioned, with conventional components, MSD has been a very grey
area as it is quite hard to prove if or how it effects components, so I am
coming in on the BGA angle in the hope of putting in place a procedure for
all MSD components.
Please email me privately if you want any more info, or how I set out my
report.
Regards,
Adrian Hanks.

I am the Purchasing Manager for a medium size Australian R&D company
involved in design and manufacture of radar & comms products for military
and civil government use.
We use almost 100% smd on our PCA's.
I have been alerted to the MSD issue and have read as much as I can get my
hands on from the IPC/JEDEC J-STD-033 and other articles to various other
publications.
It reads as a very serious issue that could be very costly to deal with.
I am putting together a paper to present to senior management on the issue,
its consequences and how my company should deal with it.
My problem is that whenever I speak to others in the industry I am told that
the whole issue is little more than a beat-up and I should ignore it and it
will go away.
Can anyone out there come back to me and give me the benefit of your
experiences and how you solved the issue.
