REFLOW SOLDERING-COMPATIBLE INTEGRATED RFID BARCODE LABEL

摘要

A surface mount technology (SMT)-compatible barcode-printable radio frequency identification (RFID) label that can be attached to a printed circuit board (PCB) work piece for tracking the work piece through an assembly line that includes at least one reflow solder process. The label is constructed from materials and components that function consistently and accurately after being exposed to the high temperature of the reflow solder process, and may further include shieling material to mitigate radio frequency interference. Preferably, the label is configured to be programmed and printed on using an RFID printer.

1. A surface mount technology (SMT)-compatible barcode-printable radio frequency identification (RFID) label configured to be attached to a printed circuit board (PCB) work piece for tracking the work piece through an assembly line that includes at least one reflow solder process, comprising:
a high temperature label substrate for providing tolerance from the reflow solder process, the high temperature label substrate comprising a printable top surface and configured to receive adhesive on a bottom surface for coupling to the PCB work piece; an RFID semiconductor circuit (IC) coupled to the substrate; an electrically conductive RFID antenna coupled to the substrate and electrically coupled to the IC; a layer of shielding material coupled to the substrate, wherein the shielding material is configured to reduce radio frequency interference; and packaging configured around the substrate, the IC, and the antenna to form an RFID label.
