I've seen boards substantially bigger than that, in high end telecom
gear (n * 10 Gb/s switches). Those were meant to sit vertically in a
card cage, perhaps 30 inches tall.
One board I saw was full of big IC, most of them with 1000 pins or
more (back in 2001). The "little ones" had "only" 600.
The backplane was a monster too, 32 layers I think.
The company is gone now.
