Shenzhen Yijin Electronics Co., Ltd.

Epson crystal oscillator, SMD crystal oscillator, quartz crystal, Epson crystal oscillator is famous for its tuning fork type quartz crystal resonator 3. series. Currently, the Epson brand is spread all over the world, and the application range of kilohertz crystals is also relatively wide. All timing products require it. The above series of crystals have small and thin quartz crystal resonators, and are particularly suitable for market areas with miniaturization requirements. They are the intermediate field that corresponds to ceramic resonators (large deviation) and ordinary quartz crystal resonators (small deviation) A product with excellent cost performance. Most suitable for B digital products, players, digital cameras, notebook computers, mobile phones, etc.

The Epson crystal oscillator brand series of kilohertz quartz crystal oscillators currently occupies the share of imported crystal oscillators in the Chinese market. The brand quality, delivery time, variety, and quality are obvious to all users. From the earliest days of crystal oscillators, 3 radio modules Since its launch, it has been applied to major well-known brands of mobile phones at home and abroad, and finally applied to the domestic copycat mobile phone market, almost occupying the crystal oscillator category of the mobile phone industry. The product itself is characterized by small size, high temperature resistance, high stability and performance, small size clock crystal resonator , is a patch tuning fork crystal, a kilohertz frequency component, used in clock modules, smart phones, and global positioning systems. Because the product itself is small and tapered, it can be used in high-performance automatic patch welding and is widely used in various A compact portable consumer electronic digital time product, the environmental performance complies with R/lead-free standards. It is packed with tape and uses automatic patching to facilitate Epson crystal oscillator.
Seiko Epson Group has developed companies around the world with employee names. Seiko Epson Company is the core enterprise of Epson Group. Seiko Epson Crystal Oscillator Yijin Electronics sells small-volume SMD crystal oscillators, and the quartz crystal oscillator products themselves have excellent The heat resistance and environmental resistance characteristics meet the reflow temperature curve requirements of lead-free soldering. The metal-cased quartz crystal oscillator allows the product to exert better impact resistance when packaged than the ceramic crystal oscillator case

What issues should we pay attention to when using imported Epson crystal oscillators? How to use crystal oscillator correctly? Will it be affected if it accidentally falls to the ground? What do you need to pay attention to when welding?
The crystal oscillator is composed of a quartz plate, an electrode, a bracket (base) or an upper cover (), etc. The key part is the quartz plate. The quartz plate is an elastomer and has a natural frequency. The quartz plate is a piezoelectric body. , when resonating, the vibration amplitude is the largest and the impedance is minimum. When detuning, the impedance increases rapidly. The frequency stabilization conditions of a quartz resonator are mainly determined by three factors: load capacitance, excitation capacitance, and frequency and temperature characteristics
Quartz crystal oscillator is a It is a fragile component, so we need to pay attention to the following points:
. Make sure that the solder points of the two pins are not connected, otherwise it will also cause the crystal to stop oscillating,
. For crystal oscillators that need to be trimmed, Attention should be paid to the influence of mechanical stress
3. After soldering, it must be cleaned to prevent the insulation resistance from not meeting the requirements
. During the crystal oscillator soldering process, the soldering temperature should not be too high and the soldering time should not be too long. , to prevent the crystal from internal changes and instability
. When the crystal oscillator shell needs to be grounded, you should ensure that the shell and pins are not accidentally connected to cause a short circuit. This will cause the crystal to not oscillate,
. For When storing the crystal oscillator, you must first consider the humidity around it, take anti-extrusion measures, and store it in a dry and ventilated place to prevent the crystal from getting damp and causing changes in other electrical parameters
. For fragile crystal oscillator devices Shockproof measures must be taken, and it is not advisable to place it on a high shelf. It is also not advisable to drop the crystal oscillator during use. Generally speaking, a crystal oscillator that has been dropped from a high altitude should not be used again
