Based on the technique, acoustic imaging of an electronic package is realized under the dry environment (Fig. 1). Typically, the polymer films are used as the intermediate layer for water protection of the sample, and by utilizing the acoustic resonance phenomenon among water, film and the sample, higher quality acoustic image of the testing sample than that for the water immersion case can be recorded without getting the sample wet (Fig. 2). Moreover, thin materials, e.g., polymer film (Fig. 3), etc. can be characterized by analyzing the acoustic resonance phenomenon among the three media. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.
