Board Assembly
PMC Board Rev 1.0 requires two reworks:
Rework #1 (Component
U12 and S1)
Rework #2 (Component
J7)
Rework #3 (NIM input rework..coming soon)
General Rev 1.0 Board Comments:
- Component C27 is silkscreened as "R127" and component
R127 is silkscreened as "C27".
- SAMTEC headers (J13, J14, J18, and J19) should
be oriented such that the key is facing the interior of the board.
- LED resistors (R132, R131, R135, R134, R137, R136,
R140, R139) should all be 150 Ohm.
- R142 and D14 should not be populated (LED threshold
too large for 1.5V supply).
- F1 and F2 should be socketed 2A fuses.
- R2 should be a 1% 221 Ohm resistor.
- R1 should be a 1% 681 Ohm resistor.
- R138 should be 150 Ohm.
- R300, R301, R302, R303, R304, J300, and J301 should
not be populated unless TDR measurement is to be made.
