Blank (mask)
A quartz crystal blank (mask) is a piezoelectric material that is cut to the shape, dimensions, and angle determined for the crystal axis of the crystal. ... There are beveling and polishing of surface modification processing. Although it is the most common AT cut among quartz blanks, the relationship between plate thickness and quartz oscillator becomes thinner at higher frequencies and thicker at lower frequencies.
