A system for placing components on a circular circuit board comprising: a pick and place machine configured to place components on the circular circuit board; a rotary table configured to receive and hold the circular circuit board for the pick and place machine, whereby a diameter of the circular circuit board is at least 1m; at least one sensor configured to sense an off-center fiducial on the circular circuit board after association with the rotary table; at least one processor connective with at least one computing memory (1425, 1430) having therein non-transitory computing code which, when executed by the processor, is configured 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 circular circuit board into at least two circular sectors based on the sensor data; accessing at least one placement program for placement of at least first components by the pick and place machine into a first one of the at least two circular sectors according to the physical location of the off-center fiducial; monitoring for a change to a location of a second one of the at least two circular sectors according to the sensor data such that the second one of the at least two circular sectors is proximate to and underneath the pick and place machine based on rotation of the rotary table; and accessing at least one second placement program for placement of second components by the pick and place machine into the second one of the at least two circular sectors upon a change to the physical location of the off-center fiducial. a pick and place machine configured to place components on the circular circuit board; a rotary table configured to receive and hold the circular circuit board for the pick and place machine, whereby a diameter of the circular circuit board is at least 1m; at least one sensor configured to sense an off-center fiducial on the circular circuit board after association with the rotary table; at least one processor connective with at least one computing memory (1425, 1430) having therein non-transitory computing code which, when executed by the processor, is configured 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 circular circuit board into at least two circular sectors based on the sensor data; accessing at least one placement program for placement of at least first components by the pick and place machine into a first one of the at least two circular sectors according to the physical location of the off-center fiducial; monitoring for a change to a location of a second one of the at least two circular sectors according to the sensor data such that the second one of the at least two circular sectors is proximate to and underneath the pick and place machine based on rotation of the rotary table; and accessing at least one second placement program for placement of second components by the pick and place machine into the second one of the at least two circular sectors upon a change to the physical location of the off-center fiducial. receiving sensor data from the at least one sensor indicative of at least a physical location of the off-center fiducial; dividing the circular circuit board into at least two circular sectors based on the sensor data; accessing at least one placement program for placement of at least first components by the pick and place machine into a first one of the at least two circular sectors according to the physical location of the off-center fiducial; monitoring for a change to a location of a second one of the at least two circular sectors according to the sensor data such that the second one of the at least two circular sectors is proximate to and underneath the pick and place machine based on rotation of the rotary table; and accessing at least one second placement program for placement of second components by the pick and place machine into the second one of the at least two circular sectors upon a change to the physical location of the off-center fiducial.
