Quartz crystals, cut corners, piezoelectric materials, especially quartz crystals, have the characteristic of converting electrical energy into mechanical energy, and vice versa. In technological applications, this effect is utilized by applying an alternating electric field, which leads to material vibration and subsequent mechanical resonance. This electrical reaction allows for use as an electric resonator with a very high quality factor Q and low temperature coefficient.

The active component of a crystal resonator is a mechanical vibration plate ("crystal element"), which is cut from single crystal quartz and has precise orientation with the crystal axis. The resonator is coated with aluminum, silver, or gold electrodes under high vacuum and sealed in a suitable housing through cold welding or resistance welding processes. The physical size of the component and its direction relative to the axis will particularly determine the resonant frequency, its initial accuracy, its electrical characteristics, and temperature coefficient. EPSON crystal oscillators produce AT cut and SC cut crystals (among others), which are the most widely used cutting methods, with a frequency range of 800KHz to 300MHZ and excellent frequency temperature characteristics.

All crystal resonators generate a main mode for each overtone, namely thickness shear vibration, as well as excess response, namely non harmonic thickness shear modes above the resonant frequency. In addition to the commonly used thickness shear C mode, there is another thickness shear mode called B mode. Compared to the C mode, it has higher frequency and lower dynamic resistance, but a larger temperature coefficient. Sometimes, in order for the oscillator to operate in C mode, it is necessary to filter that mode. The other unnecessary modes are cutting and bending. Thickness and torsional vibration may occur above or below the required resonance frequency. Through proper oscillator design, useless modes rarely cause problems. Unneeded modes close to the resonant frequency can affect the startup behavior of the oscillator or cause it to shift to the wrong frequency during operation. Other adverse effects include a decrease in frequency and resistance with temperature caused by poor modes. Parasitic mode is usually defined as the ratio of the resonant resistance of an anharmonic mode to the main mode resistance.

The application of quartz crystals in electronic devices:

Quartz crystals have multiple uses and many benefits.

One of the main benefits of quartz crystals being so useful in the production of watches, radios, and televisions is their stable and precise frequency control. We can see this in timing, IT, and communication products:

Timing: Quartz tones are also used in quartz watches, clocks, and any other device that needs to record time because they have a very stable and accurate frequency, making them an ideal choice for timing.

Information technology and communication: Quartz is also used in various technological applications, mainly for precision frequency standards in electronic devices, radio and television, fiber optic communication systems, and timing control of digital devices.

With the advancement of our technology, our dependence and use of electronic products have rapidly increased, and quartz crystals have become increasingly important. Now, there are billions of quartz products used in various electrical appliances.

From computers and smartphones to radios and GPS devices, quartz crystals are now the core component of many of the most commonly used appliances that we rely on in our daily lives.
