Well, you've really done it this time. I did 52 layer stuff that was half that size and 42 layer stuff 17x21 and one 60 layer that was 24x24 but through hole. Ain't it fun? For the 52 layer stuff, we did 1200 I/O devices as CCGA. For the 42, we did 3400 I/O MCM's with some interesting twists. Did them on Universal and Siemens. Mydata used at HP had the big capability for 24x24. Don't know why I'm discussting this but it is interesting. You sure know how to have fun.
