The characteristic of SMD chip crystal oscillator is that the chip mainly avoids manual welding, the manual welding time cannot be controlled, the time of the chip pad is stable, no plug-in is needed, and the speed is fast

     The common SMD crystal packages SMD5032, SMD6035, and SMD7050 are SMD7050, which is 7×5mm in size.

　  Volume:

　  There are mainly seven types of SMD crystal oscillators: 5070, 6035, 5032, 4025, 3225, 2520, 1510; among them, 6035 and 4025 are not commonly used.

     SMD crystal is a surface-mount quartz crystal. It is a crystal oscillator without protruding pins, which can provide high-precision oscillation. Because its shape is similar to a chip, it is called a SMD crystal. SMD crystal oscillators are also divided into passive crystal oscillators and active crystal oscillators. The English names of passive crystal oscillators and active crystal oscillators (resonance) are different. The passive crystal oscillator is crystal (crystal), while the active crystal oscillator is called oscillator (oscillator).器).

     The SMD crystal oscillator industry has become a hot spot in China's domestic market. Not only is it easy to use, its performance is more stable, and it saves labor. It has made a huge contribution to this era of lack of work, and it saves time and effort compared to plug-in crystal oscillators.

     The main application markets of SMD crystal oscillators include wireless communications, portable digital and automotive electronics, among which mobile phones and digital products are the largest. The continued popularity of the above-mentioned markets has made the global quartz crystal oscillator market extremely fierce at present. In order to reduce costs, Chinese mobile phone manufacturers are shifting from OEM manufacturing and purchasing boards to purchasing components, which will undoubtedly promote the localized procurement of SMD crystal oscillators. It is precisely based on this bright market prospect that local SMD crystal oscillator suppliers have increased their production capacity on such a large scale, which is likely to lead to oversupply, which will cause a drop in product prices. The high production cost of SMD crystal oscillators makes them unavailable. Under conditions of decline, the main cost of SMD crystal oscillators comes from raw materials, base housings, and fully intelligent frequency modulation testing equipment, while the main raw materials, bases and equipment are still monopolized by a few Japanese and American companies, so the cost is difficult to reduce significantly. .
