Switching to the metallurgical microscope in a top-down view, looking at a good bond first, we can see a rough textured surface on the gold contact pad, with the gold wire coming in from one side and compressed into a crescent shape by the ball-bonding capillary (hence why some sources refer to the second bond as a “crescent bond”). The gold wire and gold pad appear to be well connected, and a deep circular indentation is visible in the pad which goes through the gold into a silvery base metal.
