This paper deals with the design and fabrication of durable radio frequency identification (RFID) passive tag with inductive coupling, operating at ultra-high frequencies, dedicated to the identification and monitoring of professional textile products. A reliable architecture for the tag transponder is proposed, featuring a minimal number of galvanic contacts: The two pins of the integrated circuit are connected to the terminals of the inductive coupling loop by using surface mount technology welding. The transponder is encapsulated with an electrically insulating material which is waterproof and resistant to mechanical, thermal, and chemical stress. The antenna is inductively coupled to the transponder through a double loop which substantially reduces the length of the tag and significantly improves the coupling factor, enabling the tag to operate at a low power level. The reliability and flexibility of the tag is obtained by using appropriate materials and manufacturing methods for the ultra-high frequency (UHF) antenna by embroidering a multifilament stainless steel wire on textile support. The washing cycle tests have validated the applicability of this flexible and washable RFID tag, and its electromagnetic performance was experimentally assessed in an independent laboratory.

“…The global results reported in these articles show that the three parameters: temperature, long time of test and pressure, affect the reliability of ACP. Moreover, the effect of thermal cycling and humidity on the reliability of RFID tags has been studied in [11][12][13][14] at high temperature and humidity levels, as well as variation in these factors, may cause stresses on the structure, and change material parameters. However, fewer ALT results of reliability under thermal storage have been published.…”

This paper proposes to study the effects of thermal storage on the reliability of passive UHF RFID tags. Two types of tags M1 and M2 from two different manufacturers are aged under two high temperatures equal to 413 K and 433 K. Tested tags are put into a thermal storage oven hang fixed terms. The performances of these tags are measured after each aging phase to determine the power loss caused by the high temperature storage. Then a mathematical approach is used to estimate for both tags from the two manufacturers the law of reliability under nominal conditions. Statistical and physical analyses of the results allow us to study and analyze the mechanisms of aging. It is observed that the failure mechanisms depend on the type of passive tags and the values of selected storage temperatures for the tests. The scale parameters of M1 tags aged at 413 K are around 280 hours, whereas the scale parameters of the M2 tags aged at same temperature are around 360 hours. Cracks on the antenna are observed with the higher temperature equal to 433 K for M1 tags. However, the changes of the performance of others tags are probably caused by changes in the matching of the impedance between the antenna and the RFIC. From this study, various failure mechanisms demonstrate the necessity of determining the type of passive tags and the used temperature.

“…ACA materials have commonly been used in electronics applications, for example, in the attachment of driver chips in display applications and in the attachment of chips in radiofrequency identification tags. However, as ACAs are very versatile materials, the interest in using ACAs in sensor applications has increased [6]- [8].…”

Sensors are used increasingly in different applications. In some of these applications, they need to be able to tolerate harsh environments and also operate for long periods of time. One of the most challenging environments is corrosive media which may be present in many applications. In this paper, the reliability of humidity sensors attached to an FR-4 substrate was studied using a salt spray test to determine their tolerance for corrosion. Because of their structure, the attachment methods for the sensor components were restricted. Consequently, the sensor components were attached using flip chip technology with two different anisotropic conductive adhesives (ACAs). Afterward, the reliability of the sensor components was investigated using the salt spray test. During testing resistance of the ACA interconnection was measured in real time. To extract the failure mechanism, an extensive failure analysis was performed with scanning electron microscopy. The main failure mechanism was found to be corrosion of a polymer film in the sensor component. The results showed that ACA is promising material for sensor attachments, as most of the sensor components were able to withstand a considerable period of time under the salt spray test without failures.
