Method of making RFID devices
First Claim
1. A method of making an RFID device, the method comprising:
- temporarily coupling together a first portion of the RFID device to a second portion of the RFID device while the RFID device is continuously moving, using an adhering material placed on one or both of the portions;
feeding the first and second portions to a buffer zone; and
subsequent to the coupling, ultrasonically welding the portions together while the RFID device is intermittently moving from the buffer zone.

Abstract
A method of making a radio frequency identification (RFID) device includes temporarily adhering an RFID interposer to an antenna, and subsequently ultrasonically welding the interposer leads to the antenna. The temporary adhering may involve use of any of variety of suitable adhering materials, such as an adhesive, wax, or even water. The adhering and the ultrasonic welding may be parts of a process that involves mostly continuous movement of an antenna web that has multiple antennas on it. The adhering material temporarily holds the interposer in place prior to the ultrasonic welding, which is important in a process that involves a moving web. The adhering may be such that there is no material between the conductive material interposer leads, and conductive material of the antenna. This allows the ultrasonic welding to proceed without any need to push intervening material aside.

19. A method of making an RFID device, the method comprising:
-
advancing a first web containing a plurality of interposers; separating each of the plurality of interposers from the web; providing an antenna web having a plurality of antennas; transporting each of the plurality of interposers to the antenna web; temporarily coupling together each of the plurality of separated interposers to the antenna web while the antenna web is continuously moving, using an adhering material; and subsequent to the coupling, ultrasonically gang welding together the plurality of interposers to the antenna web while the antenna web is intermittently moving.
