Abstract
An acoustic stack for ultrasonic transducers comprising a backing block, flexible printed circuit board, piezoelectric ceramic layer, and acoustic matching layer. The various components of the acoustic stack are bonded together using an adhesive material and high pressure in a lamination process. The piezoelectric ceramic layer is manufactured to provide electrical and acoustic isolation without the need for dicing through multiple layers of the acoustic stack. A flex circuit provides the necessary electrical connections to the electrically isolated electrodes of the piezoelectric ceramic layer.
