I have been keeping track of some basic statistics on boards that I've seen or worked on. For some more explanation on terms and definitions, refer to this previous article. Here are a some more from the past year.
| PCB Technology | Net Count | Pin Density (pins / sq. in.) | Board Coverage | Power Density (W / sq. in.) | Design Difficulty Rating |
| 22 layer, through via | 1305 | 22.82 | 27.8% | 0.08 | 1 |
| 12 layer, through via | 1022 | 31.40 | 48.7% | 0.33 | 2 |
