Quartz crystal oscillator is a quartz crystal resonator made of quartz material, commonly known as crystal oscillator. 
It plays the role of generating frequency, has stability and good anti-interference performance, and is widely used in various electronic products.

The structure of the quartz crystal oscillator (crystal oscillator for short) is a resonant device made of the piezoelectric effect of a quartz crystal (structured body of silicon dioxide). 
Its basic structure is roughly as follows: Cut a thin slice at a certain azimuth angle (referred to as a wafer, it can be square, rectangular, or circular, etc.), coat silver layers on its two corresponding surfaces as electrodes, and solder a lead wire on each on the pins, coupled with the package shell constitutes a quartz crystal resonator, referred to as quartz crystal or crystal, crystal oscillator. 
Its products are generally packaged in metal shells, but also in glass, ceramic or plastic packages.

Due to AKM fire in October, 2020, many suppliers are not accepting new order for Quartz crystal oscillator.
But Kingtronics team can help you, please feel free to share us your request.

Japan's Asahi Kasei (AKM) semiconductor factory broke out fire on 21st October and ceased production. 

The impact of the fire on the supply and performance is still unclear. Many customers are worried about the TCXO L/T and production status . 

Kingtronics can support you steady L/T around 3~5 weeks with RoHS certified.. welcome your inquiry! 

It is estimated that the output value of quartz components in 2019 and 2020 will be 34.0 and 3.52 billion US dollars, respectively.
It continues to grow steadily, and since it is mostly a customized product, there are no supply and demand gaps and significant price increases; quartz components continue to benefit from the trend of miniaturization, and most of the components are customized products, and customer demand is stable.

In 2020, it is estimated that due to the increase in demand for 5G mobile phones and Netcom equipment, the industry trend is expected to continue to grow steadily.
The production of quartz components was reduced in 1H19 due to Japanese manufacturers, and the market supply decreased.
What's more, it is estimated that some components will be tight in 2H20, which will cause a new wave of component price increases.

How about turning to Kingtronics, our Quartz Crystals can support you favorable price and stable L/T 3-5 weeks with RoHS certified.  Remain at your service!

Imagine a perfectly innocent quartz crystal that has grown to considerable size. It is lying there, at the bottom of a shallow sea, when a meterorite rudely invites itself to crash into the Earth's surface with considerable noise, pressure, heat.

There is so much pressure and heat, in fact, that only a meteorite or asteroid can cause what happens next: the quartz is shocked!

Shocked quartz is quartz that has been subjected to an event that cannot happen from normal Earthly causes and which has had its very planar structure changed. The only two known causes of shocked quartz are nuclear explosions such as the Alamo field and the incredible impact forces of meteorites or ancient asteroids. The Pleistocene/Holcene astroid impact is one of the biggest culprits. This impact occured in North America about 12,000 years ago, creating a type of brecciated rock called impact breccia.

One aspect of the impact that creates shocked quartz, however, is that high heat is not involved, or the quartz would revert to its original structure. In some shocked quartz samples, the quartz resumed its normal growth pattern within a section of planar deformities.

Brecciated rock is like gravel that is cemented together in a finely grained matrix that may or may not have the same composition as the gravel. Impact breccia is formed through extra terrestial or nuclear impact and is generally found in or around impact craters.

Quartz crystals are said to be the second most abundant substance in the Earth's crust. They are composed of silicon-oxygen tetrahedra where one oxygen molecule is shared between each two tetrahedron. The crystals grow perpetually in a six sided prism that terminates in a six sided pyramid.

Shocked quartz crystals contained shocked lamellae, or small fractures that create lines in the quartz that go along the planes of the crystal.  These planes can usually only be viewed under a microscope. \

But often, special microscope techniques, such as electron microscope, high resolution transmission electron microscopy (TEM), Focused Ion Beam (FIB) tomography, cross polarization, reflected light, thin slicing and polishing are required before the microscopic deformations can be seen.

Sometimes, the deformations actually can be examined as if they were "pressure gauges", with various deformities helping to identify the amount of pressure that it would have taken to create them. New methods of examining the samples are being used, with goals of gathering more information and images of smaller and younger samples.

The most famous sites for such impact craters include the Chicxulub structure on the Northern Yucatan Penninsula of Mexico, the Bavarian Town of NÖrdlingen, Arizona, India, and generally in the K-3 boundary between Cretaceous and Tertiary rocks.
