Ultrasonic transducer array and method of making and packaging the same

Abstract

The invention provides an ultrasonic transducer array, which includes a receiving and emitting layer for emitting and receiving ultrasonic signals, an anode layer arranged on the first side of the receiving and emitting layer, and an anode layer arranged on the receiving and emitting layer opposite to the first side. the negative electrode layer on the second side. The receiving and emitting layer and the positive layer are divided into multiple ultrasonic transducer array elements, so that each of the multiple ultrasonic transducer array elements has its own positive pole, and the multiple ultrasonic transducer array elements have a common negative pole . The invention also provides a method of manufacturing and packaging an array of ultrasonic transducers. The ultrasonic transducer array provided by the present invention can detect a larger tissue area at the same time, obtain more complete lesion information, shorten diagnosis time, and can perform three-dimensional image imaging, thereby obtaining more intuitive image information.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an array of ultrasonic transducers and a method for manufacturing and packaging the array of ultrasonic transducers. Background technique [0002] As a non-invasive, painless, convenient, intuitive and effective inspection method, ultrasonic diagnosis has been widely used in the medical field. The main device used for ultrasonic diagnosis is the ultrasonic transducer. The structure of the ultrasonic transducer currently used is mainly a single array element Or a one-dimensional linear array ultrasonic transducer array, the main reason for limiting its clinical application is that the manufacturing method is complicated, the parallel processing is difficult, the high-density array packaging and interconnection are difficult, and the fast sending and receiving problems have not been reasonably solved. [0003] The traditional manufacturing method of an ultrasonic transducer array i...

Problems solved by technology

In this manufacturing method, the size of the slit is limited by the specifications of the blades, so it is impossible to make a high-density transducer array; and when the number of transducer array elements increases and the unit size is further reduced, the interconnection wires of the transducer anodes cannot be drawn out.

Therefore, the traditional method of manufacturing ultrasonic transducers cannot meet the demand for ultrasonic transducers in the medical field in the future.
