HIGH TEMPERATURE RFID TAG

摘要

A high temperature RFID tag (10,20) is described which has a survival temperature in the range of approximately -40.degree.C to 300.degree.C and an operating temperature of approximately -20 .degree.C to 200 .degree.C . The RFID tag comprises a housing (21) comprising a first thermally resistant material and having a base (24) and a top (22), and a circuit board substrate (26) which includes an IC circuit (28) and is disposed in a tag chamber (36), the substrate comprising a second thermally resistant material which is encapsulated in the housing. The thermally resistant materials exhibit a deflection temperature in a range of 287 .degree.C to 320 .degree.C.
