Jauch CRYSTAL QUARTZ,Rhythmus und Energie - die Krafte, die die Welt bewegen und vorantreiben. Unsere Welt bei Jauch wird ganz besonders von diesen Impulsen gepragt. Denn Frequenzbauteile und Batteriela sungen bestimmen unseren Alltag und geben bei uns taglich den Takt und die Energie vor. Darüber hinaus sind es aber vor allem unsere Mitarbeiter, die Jauch zu einem ganz besonderem Unternehmen machen. 

In unserem Blog nehmen wir Sie mit auf eine Reise über unsere Produkte, Mitarbeiter und die Jauch-Unternehmenskultur und geben Ihnen spannende Einblicke hinter die Kulissen der Jauch-Gruppe. Wir freuen uns darauf, mit Ihnen in Dialog zu treten!

节奏和能量 - 推动和推动世界的力量。我们在Jauch的世界特别受到这些冲动的影响。因为频率元件和电池解决方案决定了我们的日常生活,并为我们提供了每一天的节奏和能量。此外,它主要是我们的员工,使Jauch一个非常特殊的做企业。

在我们的博客中,我们将带您了解我们的石英晶振产品,员工和Jauch企业文化,并让您深入了解Jauch集团的幕后故事。我们我们期待着与您进行对话!

每个应用都有频率偏差容差预算，即使在最差的情况下也必须遵守，以确保应用正常工作。因此，开发人员必须了解可能导致频率偏差的所有因素。这些因素的所有最坏情况的总和不得超过应用的极限。

石英谐振频率频率偏差的可能原因有:

  • 25°C时的频率容差
  • 温度范围内的频率稳定性
  • 长期老化
  • 电路的C不匹配L
  • CL负载电容容差引起的误差

开发人员必须将这些偏差的总和与他的应用程序的公差预算进行比较，并采取任何必要的纠正措施。

长期老化因素

振荡晶体谐振频率的长期变化称为老化。

老化过程发生在每个组件中。尽管石英晶体Quartz crystal在最终调整和密封前经过复杂的干燥过程，然后在惰性气体下密封，但导电胶中的微量溶剂和微量氧气仍留在元件中，并在元件中长期反应。这种反应导致石英上永久的频率变化，称为长期老化。

在计算容差预算时，开发人员必须将应用程序生命周期中的频率变化考虑在内。在个别情况下，标准石英的通常长期老化率在头十年高达+/-20ppm。这是一个饱和过程，在更高的温度下会加剧，因此会更早生效。Jauch CRYSTAL QUARTZ.

预老化提高整体性能

许多应用要求高频率精度。对于此类应用(局域网、无线网络、蓝牙等。)，严重的长期老化是不行的。这就是为什么Jauch开发了专门针对此类应用进行优化的特殊石英晶体。与许多其他改进一起，这些WA(无线应用)晶体在生产过程中通过在恒温箱中的中间存储进行人工预老化，从而在10年的应用中极大地减少了老化，最大值为+/-7ppm。

Jauch的WA晶体非常适合要求较小公差预算的应用。

通过使用来自Jauch的这种WA晶体，开发者可以预先避免在他的应用中由严重的长期老化引起的问题。因此，这些器件非常适合(以及许多其他优化)要求较小容差预算的无线和网络应用。

Each application has a tolerance budget in terms of frequency deviation that must be adhered to even in the worst case scenario in order to ensure that the application functions. Developers must therefore be aware of all factors that can lead to frequency deviations. The sum of all worst-case scenarios of these factors must not exceed the limits of the application.

Possible causes of frequency deviations of a quartz resonance frequency are:

  • Frequency tolerance at 25°C
  • Frequency stability over temperature
  • Long-term aging
  • Mismatch of the circuit’s CL
  • CL error due to load capacitor tolerance

The developer must compare the sum of these deviations with his application’s tolerance budget and take any necessary corrective action.

Long-term aging factor

The long-term change in the resonant frequency of an oscillating crystal is called aging.

Aging processes take place in every component. Although the quartz crystals are dried in a complex process before final adjustment and sealing, and then sealed under inert gas, minute amounts of the solvents in the conductive adhesive and minute amounts of oxygen remain in the component, where they react over the long term. This reaction leads to a permanent frequency change on the quartz, which is called long-term aging.

The developer must take this frequency change over the lifetime of the application into account when calculating the tolerance budget. The usual long-term aging rate for standard quartz is up to +/-20ppm in the first ten years in individual cases. This is a saturation process that intensifies at higher temperatures and thus takes effect earlier.

Pre-aging for improved overall performance

Many applications require high frequency accuracy. For such applications (LAN, Wi-Fi, Bluetooth, etc.), severe long-term aging is not acceptable. That is why Jauch has developed special quartz crystals that have been optimized specifically for such applications. Along with many other improvements, these WA (wireless application) crystals are artificially pre-aged during production by intermediate storage in temperature chambers, thus greatly reducing aging to a maximum of +/-7ppm over 10 years in the application.

WA-Crystals from Jauch are very well suited for applications that require a smaller tolerance budget.

By using such WA crystals from Jauch, the developer can avoid problems caused by severe long-term aging in his application in advance. The devices are thus very well suited (along with a number of other optimizations) for use in wireless and networking applications that require a smaller tolerance budget.
