VME board for particle physics experiment

This is a board for a particle physics experiment which is essentially an ECL fanout board. The board arrived in 10 days which is pretty fast! The overall quality was very good and I didn't have any problems with the board. The one problem was that the PCBs were warped, i.e. they were not flat. The board was rather large (10 in by 15 in), and it was only 1.6 mm width. This is my first time getting a PCB so I'm not sure exactly what to expect, but the boards were definitely curved which made them look funny when installed in the VME rack.
