Hi Technos,

I am reviewing have a PCB design draft which has 2 MEG-Array BGA connectors from FCI. The problem is that one is on the topside and the second one on the bottom side, their locations perfectly overlapping. Otherwise said they one on top of the other.

I remember having seen a thread on Technet a few years ago stating that this construction is not reliable. Unfortunately I cannot find the e-mails in the archive.

What would be your take on this?

Thank you,
Ioan
