Two items for which I am seeking help:

1. I am looking for information on the maximum size of ceramic
capacitor/resistor components recommended for soldering on FR4. Papers have
suggested a limit of 1206 (or 1810/1812 if the termination is AgPd).

I realise that some discussion took place on this subject via TechNet
already - unfortunately before it became relevant to me.

I would greatly appreciate any suggestions or copies of messages from the
previous discussion.



2. Any information or paper references for reliability data of ceramic PGAs
soldered to FR4 would be much appreciated.
