Abstract

Disclosed is a marker assembly for printed circuit boards. The marker assembly is mounted in the top head of a PCB Test Fixture. The input signal to the marker assembly is derived from a computer via an industrial I/O board. This signal pulses the solenoid on the marker assembly to mark the PCB if no failures are detected. When the solenoid is activated it drives the wick retainer housing towards the printed circuit board. The contact of the wick onto the PCB places an ink mark to identify it as a good PCB. The wick retainer housing is spring loaded to return the housing to its rest position against the solenoid, upon completion of the marking. (Image Omitted)

Printed Circuit Board "Test Good" Marker for Use in a PCB Test Head

      Disclosed is a marker assembly for printed circuit boards. The
marker assembly is mounted in the top head of a PCB Test Fixture.
The input signal to the marker assembly is derived from a computer
via an industrial I/O board.  This signal pulses the solenoid on the
marker assembly to mark the PCB if no failures are detected.  When
the solenoid is activated it drives the wick retainer housing towards
the printed circuit board.  The contact of the wick onto the PCB
places an ink mark to identify it as a good PCB.  The wick retainer
housing is spring loaded to return the housing to its rest position
against the solenoid, upon completion of the marking.
