High-quality Development Research Tour: High-precision and Cutting-edge Products in the Workshop - Small Oscillators Break into a Big Market

As the "heart" of electronic devices, quartz crystal oscillators are widely used and can provide stable frequency signals for mobile phones, computers, and even satellites and spaceships. In the fourth article of "High-Quality Development Research Tour - High-Precision and Cutting-edge in the Workshop", let's take a look at the leading quartz crystal oscillator enterprise located in Tangshan and see how this small oscillator has broken through the huge market.

Look, what I'm holding in my hand is a quartz crystal oscillator. Its application range is very wide. It is involved in everything from the smart wearables we wear to large medical devices.

The birth of high-precision and sophisticated products cannot be separated from harsh environments. Now I have come to the production workshop of quartz crystal oscillators. Look, I am now even more strictly protected than before. How are quartz crystal oscillators made?

Yang Jing, Manager of the Crystal Production Department of Tangshan Guoxin Jingyuan Electronics Co., LTD.

In our automated production workshop, employees only need to press the start button gently on our touch screen. The materials such as wafers are transmitted through the automated system and go through our process of dispensing, curing, fine-tuning and soldering. Then, our quartz crystal oscillator is produced.

The quartz crystal oscillator I'm holding now is the smallest in size. It's only 1.6 millimeters long and 1.2 millimeters wide. The thickness of the quartz chip inside it is only one seventeenth of a human hair.

For such ultra-high fundamental frequency oscillators, photolithography technology must be used. For this reason, we have also built a leading photolithography workshop in China. The current highest frequency can reach 312 million times per second and is widely applied in fields such as artificial intelligence and high-computing power servers.

AI intelligence is also a key development direction for us. In the next step, we will benchmark against international leading enterprises, master the processing technology of chip frequency components with ultra-high fundamental frequency, ultra-high stability and ultra-small size, research and design more high-end frequency component products, and actively support the domestic substitution of materials and the new infrastructure field.
