COMPACT AND DURABLE BUTTON WITH BIOMETRIC SENSOR HAVING IMPROVED SENSOR SIGNAL PRODUCTION AND METHOD FOR MAKING SAME

摘要

A biometric sensor and button assembly and method of making same are disclosed which may comprise: a button housing comprising at least two side walls each forming a vertical load absorbing tower and defining an opening within the button housing; an insert within the opening within the housing; a sensor controller integrated circuit positioned within a cavity formed in one of the insert, the housing or a combination of the insert and the housing; and the insert and the housing cooperating to absorb vertical loading on the button housing, thereby protecting the integrated circuit from excess vertical loading. The assembly and method may also comprise the biometric comprising a fingerprint sensed by the biometric sensor. The assembly and method may also comprise the at least two side walls comprising at least four side walls, the cavity being formed within the bottom of the insert, within the housing, or both.
