Embodiment Construction

[0023] As mentioned above, one of the challenges associated with manufacturing high frequency ultrasound transducers is performing the step of electrically connecting multiple conductive leads or traces to the individual transducer elements of the transducer array without interrupting the array transduction. performance of device components. Previously the conductive traces had to be manually aligned to the transducer elements, after which they were handled with care until the manufacturing process was complete. Accidental bumping of the transducer assembly or improper alignment of the traces can result in part rejection. This problem becomes more acute as the operating frequency of ultrasonic transducers increases and the transducer elements are miniaturized. The techniques described herein simplify the manufacturing process steps of aligning and connecting the conductive traces to the individual transducer elements of a transducer array.

Abstract

An ultrasound transducer has an array of transducer elements that are electrically coupled to electrical conductors. In one embodiment, the conductors are included in a flex circuit and engage a conductive surface formed on a number of outwardly extending ribs on a frame that holds the ultrasound array. In one embodiment, the flex circuit includes an alignment feature that engages a correspondingregistration feature on the frame so that the traces on the flex circuit align with the ribs on the frame.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 62 / 260,213, filed November 25, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The disclosed technology relates to ultrasonic transducers, and more particularly to methods of manufacturing high frequency ultrasonic transducers. Background technique [0004] In medical imaging or animal research applications, use high-frequency ultrasound to study the details of fine tissue structures and moving objects in small areas of interest. In the field of cancer research, for example, high-frequency ultrasound is used to study the effects of drugs and other treatments on laboratory animals such as mice. Most diagnostic ultrasound systems utilize arrays of 64, 128, 256 or more ultrasound transducer elements formed from piezoelectric materials. When excited with a voltage pulse, the transducer elements generate ultrasound waves and, w...
