What purpose does this board serve?

• Connect bricks into the distribution board, while allowing them to be unpluggable in the event of failure.
• Pass on/off line and SMBus to bricks

To what boards (or enclosures etc) does it connect?

• Distribution board
• Bricks should be thermal pasted to the bottom of the box, but were not

What priorities did you have in your design? What design considerations did you have? What methodologies did you follow? (routing a differential pair, keeping something separate for isolation, etc)

What changes were made to your board from the previous year(s)?

• Added SMBus connections
• Used more pins and different placement of connectors

What factors affected your board outline?

What reference materials did you use for circuits? (Provide links to these)

Bricks Datasheet

What is the throughput of your board (power, data/speeds, etc)?

Why did you pick certain components for your board? (If you don't know the answer/were told, now is a great time to ask)

• Aluminum bulk caps offer a large amount of capacitance (330 uF a piece) and are rated for 60V(?) so they can be used on the 48V rail.

What issues did you have with your board (in both design and assembly)

• Soldering the brick "level" into the bricks boards was tricky

How did you go about integrating with mechanical? What changes did you make?

Other notes: what else about your board should be mentioned?

What errors/mistakes were made?

• Address resistor pins were left floating
• Connectors were not keyed

If you had to do it over again, what might you change?
