Abstract
Apparatus and associated methods relate to a flexible high-temperature-tolerant RFID tag having an RFID integrated packaged in an SOT package attached with a high temperature solder to a flex circuit defining an RFID antenna. In an illustrative embodiment, the flexible high-temperature-tolerant RFID tag may be encapsulated in a flexible material. For example, the SOT packaged RFID integrated circuit may be encapsulated in rubber. In some embodiments the entire assembled RFID tag may be encapsulated in rubber or another flexible compound. In some embodiments, such flexible high-temperature-tolerant RFID tags may be advantageously used in high-temperature applications. In an exemplary embodiment, flexible high-temperature-tolerant RFID tags may be attached to products that may be flexible and/or deformable. In an exemplary embodiment, a flexible high-temperature-tolerant RFID tag may be molded into a rubber that will be used in a flexible application.
