Ultrasonic Evaluation of Beryllium-Copper Diffusion Bonds

With respect to diffusion bond quality, an ideally perfect unbond (beryllium-copper/air) wouldyield a reflection coefficient of 0.99978, whereas an ideally perfect bond would yield a reflectioncoefficient of 0.0, leaving only backscattered grain noise as the dominant signal. For bonds ofpoor to intermediate quality the reflection coefficient is generally inversely proportional to thebond quality, meaning that the peak amplitude decreases with increasing bond quality. Thisrelationship has been observed to be invalid, however, when the kissing bond condition isencountered. The above statements are shown graphically in Figure 2. The calculations justdescribed determine the reflection coefficient
