Hi all ya'll!!
Haven't heard anything from my big mouth in quite a while have ya'?
Well, I just got back from two glorious weeks of vacation in beautiful
(but rainy) North Carolina...that's why I've been so quiet.
Anyways, it's about Moisture Sensitive components. You may recall
my posts from a while back about us trying to get our stockroom people
more in tune with MS components and proper handling, and they've been
doing a great job. They come to me with a lot of questions and I actually
like that. Shows me that they're trying to make sure they get it right.
Well today one them came to me today with some parts that were packaged
and labeled MSL 3, but they were ceramic Pin-Grid-Arrays?!?
You can how they were packaged and labeled at:
http://www.stevezeva.homestead.com click on Picture Page 2 and look at
Ceramic PGA Packaging to see how they came to us.
I've always thought that ceramic parts were not subject to moisture related
concerns, am I wrong once again?
It's a Cypress part, PN # 5962-9759802QXC (Military part). I called
Cypress,
to verify if it was a MS component or not, and got their outsourced
technical
support line (I think from India), and I was told I had to "submit a case"
email
to get my question answered.
I think somebody suggested last time when I posted about this, that
distributors
are putting MSL labels on everything just to be safe, whether a component
is
MS or not....are any of you experiencing this?
Kind regards,
