Hans,

I've had great success with the Struer's Accutom-50 Precision cut-off system.  It can do both precision cutting (and you can program for example to "automatically" dice up a 225 I/O BGA into 15 rows of 1 ball wide each...) and/or do precision grinding where you "mill" down a surface a mil or less at a time. See http://www.struers.com/cutting.htm.

> Hi Everybody,

> I was wondering if anybody could give me some leads on a versatile
> microsectioning system?
>
> I'm looking for a system which allows accurate microsections without needing
> to route the board or drill it for the registration pins.
>
> What's a reasonable accuracy? I don't really know  *2 mils?  *1 mil.
> Accuracy that doesn't add a zero to the price.
>
> Ideally, I need something that could do cross,  z axis or angled sections.
> By z axis I mean similar to what they did for the Body Voyage CD-ROM (not to
> gross anybody out).

> Thanks,
