I2C-SignalTestJig
Test Jig for simple signal panels
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
