福克斯要挑戰開發枕頭形狀的石英晶體FX425B-16.000,然而,這些電極的附著被證明是一個巨大的挑戰,這取決于振蕩的類型。理想情況下,電極應該附著在石英上的一個點上,在這個點上,即使在有電壓的情況下,石英晶振的變形也是最小的。使用厚度剪切振子比使用開頭提到的彎曲或縱向振子要容易得多。
然而,石英的進一步加工步驟也是必要的。在一臺特殊的研磨機中,坯料被研磨成墊子的形狀——中間稍厚,向外逐漸變細。石英支架連接到錐形端。以這種方式固定,薄金屬電極最終被蒸發到坯件的較厚的中間部分上。
因此,AT切割在石英生產中具有雙重功能。首先,它確保在-40到85攝氏度的溫度范圍內的高頻率穩定性,其次,它將坯料的形狀定義為厚度剪切振蕩器。

The attachment of these electrodes, however, proves to be a great challenge, depending on the type of oscillation. Ideally, the electrodes should be attached to a point on the quartz where it deforms only minimally, even under voltage. This is much easier with a thickness shear oscillator than with the bending or longitudinal oscillators mentioned at the beginning.
Nevertheless, a further processing step of the quartz is also necessary. In a special lapping machine, the blanks are ground until they assume the shape of a cushion – slightly thicker in the middle and tapering outwards. The quartz holder is attached to the tapered ends. Secured in this way, thin metal electrodes are finally evaporated onto the thicker middle section of the blank.
The AT cut thus fulfils a double function in quartz production. First, it ensures high frequency stability in the temperature range from -40 to 85 degrees Celsius and second, it defines the shape of the blank as a thickness shear oscillator.
