... Abstract This chapter focuses on the design of measuring devices. The devices used to measure vibration typically consist of an electronic transducer with an interconnecting cable and an alternating current voltmeter. The working principle of each type of transducer is described in this chapter...

Figure 35 Using signal amplitude for focus determination of high frequency transducers can be misleading. A 180 MHz transducer was positioned over a flip chip at the proper pulse-echo focus position. It was then moved through the focus, closer to the die. The out-of-focus position produces More

Figure 36 Using signal amplitude for focus determination of high frequency transducers can be misleading. One workaround is to perform a high digital resolution focus series such as shown here. The numbers refer to the front surface reflection water path time of flight. For this die thinned More

It then discusses the principles of operation, presentation, and interpretation of data of pulse echo and transmission methods. This is followed by sections providing information on general characteristics of ultrasonic waves...
