> Hello everyone,
>
> We have capital to put together a TDR analysis capability
> for high speed
> interconnect characterization. our focus is mainly BGA,
> leadframe and high end
> 1500+ I/O flip chip packages with interconnect length ranging
> from 2 mm to 20
> mm. As in any package construction vias, traces,
> solderballs, chip bumps etc
> make up a signal net.
>
> We are in the process of determining what equipment we would
> need to properly
> characterize interconnects ( at package level) with risetimes
> as low as 50~100
> picosecond. We would also include differential pair
> characterization as well
> since wee see the use of differential pairs at package level
> more and more.
>
> If you would send some feedback on your experience with TDR
> equipment, or a
> setup that works in high speed domain and provides good
> repeatibility, I would
> ver much appreciate your feedback.!.

> Thanks in advance
