Someone once said that human beings are called the smartest primates, because they not only have all kinds of things to help you achieve a goal by virtue of human nature, but also achieve a specific purpose and specific tools to help you achieve it. This is what Confucius said, "To do well, you must first sharpen yourself". . Of course, the object must be made first, and it must be made well, otherwise the object will just be a piece of paper in the attic.
To domestic a few crystal, also always complain old customer and purchaser must choose between the crystal of import brand domestic brand, do not want to accept him to boast arrogant for own crystal brand, and others think this is quality problem. Don't choose, always console yourself, the overseas imported crystal brand is the old brand popularity is getting higher and higher fans. What they should do is look closely at their crystal production to see what is going on that makes people worry and distrust their crystal quality.
In recent years, the crystal vibration industry in China has developed rapidly, and its annual output value accounts for about 25% of the total global output value, ranking in the forefront of the world. The crystal vibration industry in China is still developing rapidly despite the influence of macro economy at home and abroad. Smaller, more precise, more precise crystal oscillators are the key direction. In terms of the size of the crystal oscillator, we should pay more attention to its thickness. For most imported crystal oscillators, including Japanese products, the thickness of the crystal oscillator tends to increase when the length and width of the crystal oscillator decrease. However, when the crystal vibration produced in China pays special attention to this problem, the length width decreases and the thickness increases, but the volume does not change much. Therefore, domestic crystal oscillator manufacturers in the production of crystal oscillator to reduce the width and length, while trying to avoid increasing the thickness.
The vibration of a quartz crystal is a chip cut from a silicon dioxide crystal. The quality of the silicon dioxide material also determines the color of the crystal vibration. Because silica crystals are cut into very thin flakes when they vibrate, they are easily broken. As a result, crystals that appear strong in vibration are classified as fragile and must be protected when used.
Electronic products have taken a big step towards the world at an amazing speed. Crystal vibrations are always present in thousands of electronic products. Perhaps the most fashionable product is the smartphone, which has many functions due to crystal vibration. Smart phone is mainly used for 3225 chip crystal oscillator, the specification is 26M, 20PF 10PPM and cylinder 2 * 6, 3 * 8 32.768KHz crystal oscillator. Mobile phones with time display must have real-time clock control. The 32.768K quartz crystal oscillator usually USES time-related clocks, mice, keyboards, headphones, audio and other electronic products and cannot be separated from it.
The cutting process of quartz crystal is the process of drawing and cutting. The drawing action is identical to that of a plotter or film rewind. Basically, the working process can be divided into three parts of the process, such as layout, drawing, and rewind. But the control precision and stability are relatively high, need to choose high-end cutting wire (copper wire). For products with different precision rules and different crystal vibration frequencies, different sizes of line diameters must be selected. The cutting process means that the quartz vibrator will move towards the cutting line at a very slow rate (about 5 mm per minute) during the winding of the cutting line. The working table speed should be slow, the operation should be smooth and the positioning accuracy should be high. Intelligent products are easy to use, but the internal structure is very complex, all kinds of small parts together, to produce such a high precision products, for domestic production technology is undoubtedly a huge challenge. Crystal industry is one of them, in recent years the domestic crystal technology to complete the qualitative leap of the industry, from the original mass 49 u plug-in, SMD crystal size development to today's small size 5032 mm, 3225 mm and 2520 mm, 2016 mm and 1612 mm, the future prospects of crystal product performance will inevitably is high precision, high frequency, high temperature resistant, small volume, etc.
The rise of intelligent products has increased the demand for quartz crystal vibration, and the demand for better quality crystal vibration is also increasing. Although most of them are in the stage of product development, it can be seen that the recovery of the intelligent industry will once again drive the development of various industries, especially the electronic industry. The core of intelligent products is controller, including IC and ELE.
