Health is the most important, stay well.

The study on the impact of COVID-19 on the global manufacturing industry is classified into automobile, food & beverage, chemical, machinery, electrical and electronics, metal, aviation, pharmaceutical and medical equipment, and others. The electronics industry is being significantly affected due to the COVID-19 epidemic, China accounts for nearly 85% of the total value of components utilized in smartphones and nearly 75% in the case of televisions. All critical components, such as printed circuit boards, mobile displays, LED chips, memory, open cell TV panels, and capacitors are imported from China.

Now China manufacturing industry gets recovery from COVID-19, we all dedicate ourselves to provide the most economical solutions on support global requirements.

Herein we list our strongest lines to ensure customers get the most of profit and save the most of cost.

A quartz crystal resonator depends on the piezo-electric effect to work. This effect converts a mechanical stress in a crystal to a voltage and vice versa. In this way the piezo-electric effect converts the electrical impulses to mechanical stress which is subject to the very high Q mechanical resonances of the crystal, and this is in turn linked back into the electrical circuit.

The quartz crystal can vibrate in several different ways, and this means that it has several resonances, all on different frequencies. Fortunately the way in which the quartz crystal blank is cut from the original crystal itself can very significantly reduce this. In fact the angle of the faces relative to the original crystal axes determines many of its properties from the way it vibrates to its activity, Q, and its temperature co-efficient. There are three main ways in which a crystal can vibrate: longitudinal mode, low frequency face shear mode, and high frequency shear. A cut known as the AT cut used for most crystals used in traditional radio and electronics circuits uses the high frequency shear mode.
