In the field of nondestructive testing (NDT), the bond defect detection of ultra-thin metal and silica gel is a difficult problem. In this study, the ultrasonic resonance method was used to evaluate the bonding quality of ul-thin metal. Study three different bond states of ultra-thin nickel sheet and silicon film composite, nickel and silica gel bond state, the absorption of ultrasonic differences, with the use of high-frequency ultrasound in ultra-thin nickel slice of resonance, through the resonance signal analysis of ultra-thin nickel sheet and silicon film combination, the bonding coefficient of the bond state between ultra-thin nickel sheet and silica gel. Through experimental comparison, the results show that the attenuation of ultrasonic signal in the nickel sheet and silicon film with different bonding states characterize the bonding state of ultra-thin nickel sheet and silicon film by the bonding coefficient, the bonding coefficient of good parts, weak adhesive parts and debonded parts is reduced successively. By setting an appropriate determination threshold value, the bonding state between the ultra-thin nickel sheet and the silicon film can be accurately determined according to the bonding coefficient obtained by detection.

“…Venkata developed an interfacial spring model to predict ultrasonic propagation through layered medium, and the results were verified by finite element analysis (FEA) [20]. Harold proposed to use ultrasonic phase to evaluate the strength of interface stiffness, and the first time the peak phase predicted has been verified experimentally [21]. Mori N examined theoretically the reflection and transmission characteristics of Lamb waves at the bonding interface by the hybrid finite element method [22].…”

An ultrasonic evaluation method of interfacial bonding quality from layered structures is proposed for enhancing the testing accuracy. The ultrasonic reflection and transmission characteristic is theoretically analyzed, which focus on the different quality of the single and double bonding interface with spring-type. The reflection coefficient and transmission coefficient mathematic models, which include multiple parameters, are derived from the transfer matrix. Taking the first, second, and the double bonding interface as the research objects, respectively, two types of resonant frequencies have been presented by numerical solving the model, namely, the first type resonance frequency (RFI) and the second type resonance frequency (RFII). The results show that the interval of the RFⅠ is related to medium thickness of the maximum acoustic impedance. Similarly, the interval of the RFⅡ depends on other layers’ thickness. In addition, the transmission coefficient shows a change in different trends with the bonding interface gradually tending to rigid. When the adhesive layer thickness is sufficiently small compared with the wavelength, the reflection coefficient shows many local minima points at a certain frequencies range, the frequency of local minimum point increases with the increase of the stiffness coefficient. The experimental results are in good agreement with the numerical solution results and finite element analysis (FEA) results.
