PCB Design and Construction Eric Chung

Quarter Goals: Finish PCB design, send out for manufacturing, and order parts Build and test all the boards Move board designs to Altium+start working on next design Design simple board-to-board adapter card

What actually happened Finish building the cards (except the regulators) Finished testing the SEABAS card Can’t get access to Altium Working on board to board adapter 3.3V regulator card not working Started reading through High-Speed Digital Design book

Finalizing board design

Building the Cards 2V regulator card 3.3V regulator card SEABAS/T3MAPS adapter card

Testing SEABAS adapter card Tested all channels’ outputs at 5MHz with BNC probe Tested channel 7 at 5, 10, 20, and 30MHz with BNC probe Tested channel 7 and channel 1 at 1, 10, 30 MHz with TEK probe Ch. 0 output @ 5MHz with BNC probe

Tests with TEK probe Ch7 output @ 1MHz Ch7 output @ 10MHz

Tests with TEK probe Ch7 output @ 30MHz

Board-to-board adapter Connects Atlys FPGA to Multi I/O

Next Steps Working on next design for adapter cards Troubleshooting problems with regulator cards Working through High-Speed Digital Design book
