The quality of the interfaces that typically exist in integrated circuit (IC) packages was evaluated by using longitudinal ultrasonic wave propagation with contact transducers. An interface spring model was used to predict the ultrasonic reflection coefficient relationship with varying interfacial spring constants. Results demonstrate that the quantification of the interface quality is possible, and reflection coefficient can be used as a criterion.
