I spent quite a bit of time going over the entire surface of the quartz sheet with the 20x objective looking for any sign of fractures, chips, or damage, as well as inspecting both of the electrical connections from the crystal to the package for cracks or any sign of electrical defects. And I found nothing. This quite surprised me, because I expected the failure mode of a sonicated quartz oscillator to be “shake the resonator to pieces or rip it off the mount” and I was seeing nothing of the sort.
