Abstract
Ultrasonic precise bonding is an emerging technology in the application of polymer micro-assembly. The propagation of ultrasound changes with the interfacial polymer physical state in the ultrasonic bonding process. So the ultrasonic guided wave is an effective parameter to in-situ monitor the fusion degree. The time-frequency characteristics in the ultrasonic guided wave are analyzed by vibration analysis methods. The polymer interfacial fusion is online visual monitored by the high-speed HD camera. The fusion behavior of the thermal melt interface and the time-frequency characteristics are analyzed and correlated. Results indicate that the change of the interfacial thermal melt state is related to the time-frequency characteristics of the ultrasonic guided wave. The generation of the melting zone, the fusion of the melting zone, the rotation of the micro-device, the generation or disappearance of local air bubbles all lead to the changing of the harmonic frequency and intensity in the ultrasonic bonding process.
