## Abstract

An apparatus, system and method for placing components on a circuit board by a pick and place machine. The apparatus, system and method may include a rotational table suitable to receive and hold the circuit board for the pick and place machine; at least one sensor capable of sensing an off-center fiducial on the circuit board after association with the rotational table; and at least one processor connective with at least one computing memory having therein non-transitory computing code. The steps performed by execution of the code may include receiving sensor data from the sensor indicative of at least a physical location the off-center fiducial; dividing the board into radial sections based on the sensor data; accessing at least one placement program for placement of at least first components by the pick and place machine; 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 for placement of second components upon a change to the physical location.
