Hey all,

This message is going out Friday night, so I know I won't hear much until
next week. But anyways, we may be getting some work for an assembly that is
on a 2" X  2" ceramic substrate...double sided SMT by the way...

I know that things are going to be different than the standard fiberglass
substrate assemblies, IE: more heat for reflow, ect....but is there anything
else that I should watch out for?

Did some ceramic substrate stuff a while back at a past employer, but it was
single side stuff and didn't really present too much of a problem..

I was asked if we could put them in a panel, and as far as I know, you don't
want to do that unless you have some very specialized singulation equipment
to singulate each assembly. I thought I would get some workpiece fixturing
and leave them in their 2" X  2"  size...

Sorry if I'm asking dumb questions, but as once said; "The only dumb question
is the one that's not asked..."

Thanks, and I hope ya'll had a good weekend...
