1. A system for placing components on a circuit board by a pick and place machine, comprising:
a rotational table suitable to receive and hold the circuit board for the pick and place machine;
at least one sensor configured to sense an off-center fiducial on the circuit board after association with the rotational table;
at least one processor connective with at least one computing memory having therein non-transitory computing code which, when executed by the at least one processor, causes the at least one processor to perform the steps of:
receiving sensor data from the at least one sensor indicative of at least a physical location of the off-center fiducial;
dividing the circuit board into radial sections based on the sensor data;
accessing at least one placement program to determine a for placement of at least first components by the pick and place machine into a first at least one of the radial sections according to the physical location of the off-center fiducial;
monitoring for a change to a second at least one of the radial sections based on rotation of the rotational table according to the sensor data; and
accessing at least one second placement program to determine a placement of second components by the pick and place machine into the second at least one of the radial sections upon a change to the physical location of the off-center fiducial.
