High-speed RFID circuit placement method
First Claim
1. A method of placing an RFID circuit onto an electrical component the method comprising:
- securing an RFID circuit to a primary drum;
transferring the RFID circuit from the primary drum to a secondary drum; and
placing the RFID circuit from the secondary drum onto an electrical component on a moving web;
wherein the transferring includes adjusting the peripheral speed of at least one of the primary and secondary drums such that the peripheral speed of the each drum is substantially equal;
wherein the placing includes adjusting the peripheral speed of the secondary drum such that the peripheral speed of the secondary drum is substantially equal to the speed of the moving web; and
wherein at least one of the transferring and the placing includes increasing the peripheral speed of at least one of the primary and secondary drums such that velocity of the RFID circuit is increased from a relatively low peripheral speed during the securing to a relatively high peripheral speed during the placing.

Abstract
A high-speed process includes removing chips or interposers from a carrier web having a first pitch and transferring the chips or interposers to electrical components, such as RFID antenna structures, on a moving web having a second pitch. According to one method, a transfer drum transfers chips or interposers to a moving web of electrical components by picking a chip when the transfer drum is stationary, and transferring the chip to the moving web when the transfer drum is rotating such that a tangential velocity of the transfer drum is substantially equal to the linear velocity of the moving web. According to another method, a primary drum removes chips or interposers from a carrier web having a first pitch, and transfers the chips or interposers to a variably rotating secondary drum which then places the chips or interposers onto an electrical component on a moving web having a second pitch.

12. A method of placing an RFID circuit onto an electrical component, the method comprising:
-
securing an RFID circuit to a primary rotary placement device; transferring the RFID circuit from the primary rotary placement device to a secondary rotary placement device; and placing the RFID circuit from the secondary rotary placement device onto an electrical component on a moving web; wherein the transferring includes adjusting the peripheral speed of at least one of the primary and secondary rotary placement devices such that the peripheral speed of the each rotary placement device is substantially equal; wherein the placing includes adjusting the peripheral speed of the secondary rotary placement device such that the peripheral speed of the secondary rotary placement device is substantially equal to the speed of the moving web; and wherein at least one of the transferring and the placing includes increasing the peripheral speed of at least one of the primary and secondary rotary placement devices such that velocity of the RFID circuit is increased from a relatively low peripheral speed during the securing to a relatively high peripheral speed during the placing.
