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
