Test Jig for simple signal panels

 

 

I2C-SignalTestJig Version 1.0

Not built

An I2C slave board that drives 6x signal head drivers (effectively 3x IOB-Signal circuits) in a form factor that mimics the panelization spacing of the simple signal boards. This allows bulk testing after fabrication of an entire board in 2 (or 4) operations

  • align a board with the pogo pins
  • press down on pins
  • observe the correct operation of the heads
    • mark any defective units
  • move panel to next set of contacts & repeat
