Overarching decision: Physically a backplane or practically a backplane?
- Do we want the backplane PCB to physically hold all other boards and they must slot in, or are wire connections OK?
Targets (Maximum/Minimums/Targets):
...
- At least X
- JE – Don't know what systems are on boards yet, but I doubt you'll have much trouble with this
Max Voltage:
- At least X (25V?)
Fabrication Method:
- Board-independent; connector functionality should not rely on certain mechanical characteristics of the PCB
- Reversible: connector should not be irreversible or irremovable, in event of damage
- Requires no specialized, high-cost tools.
- Bonus points; ability to act as a wire-to-board connector as well, for use in debugging.
Mechanical Connection:
- Keyed; the obvious one
- Positive latching; IREC compliance, resistance to vibration
