| 1. A method of placing an RFID circuit onto an electrical component, the method comprising:
securing an RFID circuit to a transfer drum;
rotating the transfer drum; and
placing the RFID circuit from the transfer drum onto an electrical component on a moving web,
wherein rotating the transfer drum includes accelerating the transfer drum from a lower peripheral speed during the securing
to a higher peripheral speed during the placing, such that the tangential velocity of the RFID circuit is substantially equal
to the linear velocity of the moving web when the RFID circuit is placed onto the electrical component, and
wherein the transfer drum includes a vacuum source for temporarily securing the RFID circuit to the transfer drum.
