Different non-destructive methods were tested to determine the thickness of the bond wire. These methods, along with their respective advantages and disadvantages, are presented in Table 2. The analysis considered factors such as the required time, measurement accuracy, and specific characteristics of each method. The first method involved direct 2D imaging, which is the fastest but least precise. Distinguishing between the background and the object in the grayscale distribution can be challenging, especially at low intensities.
