Morning Everybody!

As some of you might have read in my past posts, I don't have much
capability (read: none) for microsectioning PCB's in-house, other than
a Dremel tool and a desire to try and see things.

Things look like they will possibly be changing in the future as far as
our microsectiong needs...we will need to have at least a basic capability
in-house to do a decent microsection. One of the things besides PCB
sections
that we will be looking at, is to be able to verify void-free underfill.

I'd like to ask those of you that do microsections all the time for a
favor. If
you had to set-up a basic capability from scratch, what would be the
minimum
things that you like to have. I can fumble around and eventually get
everything
I need, but I thought; "Why re-invent the wheel?" So I thought I would ask
you all...

Just off the top of my head, these are some of the basic things of what I
think I
should have:

1. Diamond saw
2. Series of grinding/polishing wheels
3. Potting molds
4. Potting materials
5. High magnification microscope
6. ?

If there are things that you would add to the list, please add them for me.
If there
are certain vendors of the things on the list that you feel are better than
others,
go ahead and list them as well. If you feel that you should respond
off-line on
those items, do that as well.

I'm not trying to set-up a full blown failure analysis lab, just something
that will give
us the capability to spot some of the obvious problems from a microsection.

Kind regards,
