The piezoelectric ultrasonic circuit board circuit driven transducer is mainly summarized in the following aspects:

(1) Establish an equivalent resonance model for ultrasonic transducers, study their equivalent circuit based on lumped parameters, and analyze their series resonance characteristics, providing a theoretical basis for the design of ultrasonic generator schemes.

(2) Based on the characteristics of the ultrasonic transducer, the overall hardware circuit diagram of the ultrasonic generator is designed, and the specific functions and electrical connection methods of each sub module are determined to meet the performance requirements of the digital ultrasonic generator.

(3) According to the requirements of wire bonding technology, analyze the output characteristics of the ultrasonic generator, establish a phase-locked loop real-time tracking circuit, write resonant frequency scanning, resonant frequency automatic locking, and communication module programs with the host to achieve stable and reliable ultrasonic output.

(4) Performance testing and overall debugging and optimization of the ultrasonic generator, testing the functions of each sub module, integrating it into a fully automatic wire bonding machine, optimizing the performance according to actual bonding requirements, and designing a digital ultrasonic generator that meets the requirements of high-performance wire bonding machines.
