Abstract
A high temperature RFID tag is described which has a survival temperature in the range of approximately −40° C. to 300° C. and an operating temperature in the range of approximately −20° C. to 200° C. In one embodiment of the invention, the RFID tag comprises a housing comprising a substantially flexible first thermally resistant material and having a base and a top, and a circuit board substrate comprising a substantially flexible second thermally resistant material which is encapsulated within the housing. In an additional embodiment of the invention, the high temperature RFID tag comprises a substrate assembly, the substrate assembly including a substrate having an integrated circuit disposed thereon, the substrate comprising a substantially flexible first thermally resistant material, and a high temperature encapsulant disposed on a first side of the substrate, the substrate assembly having a survival temperature in the range of −40° C. to 300° C.
