Personal data card and method of constructing the same.

摘要

A personal data card (10), comprised of a semiconductor chip (28), sealed by encapsulant (38) in an opening (26) in a body (12), is advantageously provided with a shock absorbing device (38) which substantially circumscribes the encapsulant to substantially isolate the encapsulant from the body of the card. By isolating the encapsulant from the card body, the shock absorbing device reduces the stresses transmitted from the card body into the encapsulant and into the chip when the card is flexed. In this way the incidence of cracking of the chip caused by the stresses generated upon flexing of the card is reduced.
