4-layer 3oz PCB for power management

This PCB was a somewhat non-standard stackup of four layers of 3oz copper. High currents flow through both the inner and outer layers of this board. The board was going to take 10-11 days lead time, but after talking with Grace, I was able to get the boards before the Lunar New Year holiday (7 day lead time or less) paying a little more to rush the order. I submitted the design around 10PM USA time, and after a few emails about the rush situation, I got the quote finalized that same night. The boards look great and arrived on January 28. The matte black solder mask, heavy copper, and gold finish give the board a really premium feel.
