Market News for Quartz Crystal

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.

Kingtronics team sincerely wishs you & your family have a wonderful Merry Christmas and Happy New Year 2018 in advance.

Now that winter's here, it’s more difficult to get up in the morning. In fact, more than half of us admit getting up during winter is a ‘struggle’. Unsurprisingly, Monday mornings are the hardest. So what little changes could you make? Here are 3 top tips to give you that extra ‘morning motivation’ boost:

1> Have a drink.

Drinking water as soon as you wake up will help stimulate the body and help you stay awake.

2> Do something active.

You may not have the time or energy for a full-blown exercise routine every morning, but get your body moving somehow such as forcing yourself to wiggle around under the covers.

3> Remind yourself of what you have to do.

Noting your to-do list on a small whiteboard or a piece of paper kept on the nightstand, which will help you feel at night like you have those things handled, or at least noted, for the following day, and it will give you more reason to get up in the morning.

If none of this works, there's the obvious tip of setting the alarm clock across the room. *^__^*

Dear clients, wish you enjoy a nice weekend with your families. ^_^

We cooperated with Setron from 2014, and it mergered with Arrow Electronics last year. Now we directly work with Arrow. Cheers!

Hope this can make you know more about us and share with us your precious business chance. We sincerely hope to become your strong backup force in your path to success.

•Good shock measures to ensure the Quartz Crystal don’t fall to the ground during use.

• When storing crystals, anti-extrusion measures should be prepared and stored in a dry and ventilated place, avoid damp Quartz Crystal.

• When the solder, solder temperature is not too high, the role of the solder time not too long, so as not to produce an unstable change occurs within the Quartz Crystal.

• Ensure two-pin solder points are not connected, or will lead to Oscillator is stopped.

• The shear pin, should pay attention to the effects of mechanical stress.

• Solder, it should be cleaned to prevent the insulation resistance don’t meet the requirements.
