Hi Experts ,
I have been doing mixed signal boards , Digital , Analog & RF .RF up to
5 Ghz.No big issues so far.
We are planning to do similar kind of boards with a new SOC.There is
a concern regarding the IR drop as most of the permissible margins are
eaten away at the package & chip levels.
To mitigate this effect to a larger extent , the plan is to use 2 Ounce &
higher levels of Cu thickness.So far we have been doing the mixed signal
boards with Cu thickness of 1 Oz.
Could there be any issues with this approach for the mixed signal boards ?
Appreciate any inputs in this regards.
Best Regards
Sunil.B
