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!

節(jié)奏和能量 - 推動和推動世界的力量。我們在Jauch的世界特別受到這些沖動的影響。因為頻率元件和電池解決方案決定了我們的日常生活,并為我們提供了每一天的節(jié)奏和能量。此外,它主要是我們的員工,使Jauch一個非常特殊的做企業(yè)。

在我們的博客中,我們將帶您了解我們的石英晶振產(chǎn)品,員工和Jauch企業(yè)文化,并讓您深入了解Jauch集團的幕后故事。我們我們期待著與您進行對話!

每個應用都有頻率偏差容差預算，即使在最差的情況下也必須遵守，以確保應用正常工作。因此，開發(fā)人員必須了解可能導致頻率偏差的所有因素。這些因素的所有最壞情況的總和不得超過應用的極限。

石英諧振頻率頻率偏差的可能原因有:

25°C時的頻率容差
溫度范圍內(nèi)的頻率穩(wěn)定性
長期老化
電路的C不匹配L
CL負載電容容差引起的誤差

開發(fā)人員必須將這些偏差的總和與他的應用程序的公差預算進行比較，并采取任何必要的糾正措施。

長期老化因素

振蕩晶體諧振頻率的長期變化稱為老化。

老化過程發(fā)生在每個組件中。盡管石英晶體Quartz crystal在最終調(diào)整和密封前經(jīng)過復雜的干燥過程，然后在惰性氣體下密封，但導電膠中的微量溶劑和微量氧氣仍留在元件中，并在元件中長期反應。這種反應導致石英上永久的頻率變化，稱為長期老化。

在計算容差預算時，開發(fā)人員必須將應用程序生命周期中的頻率變化考慮在內(nèi)。在個別情況下，標準石英的通常長期老化率在頭十年高達+/-20ppm。這是一個飽和過程，在更高的溫度下會加劇，因此會更早生效。Jauch CRYSTAL QUARTZ.

預老化提高整體性能

許多應用要求高頻率精度。對于此類應用(局域網(wǎng)、無線網(wǎng)絡、藍牙等。)，嚴重的長期老化是不行的。這就是為什么Jauch開發(fā)了專門針對此類應用進行優(yōu)化的特殊石英晶體。與許多其他改進一起，這些WA(無線應用)晶體在生產(chǎn)過程中通過在恒溫箱中的中間存儲進行人工預老化，從而在10年的應用中極大地減少了老化，最大值為+/-7ppm。

Jauch的WA晶體非常適合要求較小公差預算的應用。

通過使用來自Jauch的這種WA晶體，開發(fā)者可以預先避免在他的應用中由嚴重的長期老化引起的問題。因此，這些器件非常適合(以及許多其他優(yōu)化)要求較小容差預算的無線和網(wǎng)絡應用。

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.
