Abstract
Manufacturing of a novel thin and flexible radio frequency (RF) tag with a stamped metal leadframe antenna is disclosed. The tag is made by transporting a leadframe strip having leadframe antenna 'cutouts' to a point where a chip is mechanically and electrically attached directly to the leadframe antenna. A battery can be attached to the chip in the process. Processes to cut support bars holding the leadframe antenna to the leadframe strip, seal the package (by lamination or molding), and to excise the sealed component are performed in various orders to produce a final product. Intermediate support (positioners) for the thin leadframe are optionally provided add structural support to the antenna while the sealed component is made. A protective surround can be added to cover the package and to provide further structural support for the package while still permitting the sealed component to be thin and flexible.
