  • Fingerprint sensor with leadframe bent pin conductive path and associated methods
    Patent number: 6683971
    Abstract: A fingerprint sensor includes a housing, a fingerprint sensing integrated circuit in the housing, and a leadframe comprising at least one first conductive pin extending upwardly to the upper surface and at least one second conductive pin extending outwardly from the housing. The sensor also includes at least one conductive layer on the upper surface of the housing and this is connected to the at least one first conductive pin. The at least one first conductive pin preferably terminates flush with the upper surface of the housing. In other words, one or more upwardly bent leadframe pins readily establish connection to the respective one or more external electrodes. The integrated circuit may include a finger drive circuit, a wake-up circuit, and/or an ESD circuit and the at least one conductive layer may connected thereto.
