德國夸克石英晶振安裝，德國Quarztechnik夸克晶振公司是一家有著悠久發(fā)展歷程的元器件制造商，主要向廣泛應(yīng)用市場提供性能優(yōu)越，低成本高性能的石英晶振為主，為了拓寬自身的能力邊界，又針對新的市場開發(fā)大量優(yōu)質(zhì)的石英晶體振蕩器，憑借著精湛的工藝，過硬的品質(zhì)贏得大量用戶的好評，同時隨著長期的積累，實現(xiàn)價值的最大化，如今一如既往保持初心，將最好的品質(zhì)貢獻(xiàn)于世界各地。

晶振也分為無源晶振和有源晶振兩種類型。無源晶振與有源晶振（諧振）的英文名稱不同,無源晶振為crystal（晶體）,而有源晶振則叫做oscillator（振蕩器）。無源晶振需要借助于時鐘電路才能產(chǎn)生振蕩信號自身無法振蕩起來,所以“無源晶振”這個說法并不準(zhǔn)確；有源晶振是一個完整的振蕩器。石英晶體振蕩器與石英晶體諧振器都是提供穩(wěn)定電路頻率的一種電子器件。

我們已經(jīng)仔細(xì)了解了石英生產(chǎn)的最初階段，石英坯件由什么材料制成，以及從石英塊制造具有特定頻率的石英坯件需要哪些步驟。

我們現(xiàn)在處于生產(chǎn)最終元件的過程中的以下階段:石英坯件已經(jīng)生產(chǎn)出來，甚至電極也已經(jīng)蒸發(fā)，頻率也已經(jīng)檢查過了?，F(xiàn)在必須將坯件安裝到外殼中。這聽起來很簡單，但即使在這里也有一兩點要考慮，以便最終的結(jié)果是一個高質(zhì)量和耐用的石英。德國夸克石英晶振安裝.

安裝到外殼中

為了將坯件安裝到外殼中，首先用導(dǎo)電粘合劑涂覆外殼基座。下一步是固定石英坯件。

最終頻率調(diào)整

現(xiàn)在最后一次調(diào)整頻率。使用兩種不同的方法，必要時調(diào)整目標(biāo)頻率。一方面，如果頻率太高，可以氣相沉積額外的電極材料。這個步驟降低了頻率?；蛘撸玫入x子體部分去除電極材料可以增加頻率。

外殼是密封的

接下來，密封外殼。這有幾種方法。經(jīng)常使用“接縫密封”方法。在這個過程中，金屬蓋和包裝用電極焊接在一起。德國夸克石英晶振安裝.

最后階段

在接受最終測試、包裝和運輸之前，石英在激光或特殊墨水的幫助下進(jìn)行標(biāo)記。

we have already taken a closer look at the first stages in quartz production, what material the quartz blanks are made of and what steps are necessary for a quartz blank with a certain frequency to be created from a quartz block.

We are now at the following point in the process leading up to the finished component: the quartz blank has been produced, even the electrode has already been vaporized and the frequency has been checked. The blank must now be installed into the housing. It sounds simple, but even here there are one or two points to consider so that the final result is a high quality and durable quartz.

Mounting into the housing

To mount the blanks into the housing, the housing base is first of all coated with conductive adhesive. The next step is to affix the quartz blank.

The final frequency adjustment

Now the frequency is adjusted one last time. Using two different methods, the target frequency is adjusted if necessary. On the one hand, additional electrode material can be vapor-deposited if the frequency is too high. This step decreases the frequency. Alternatively, partial removal of the electrode material with plasma can increase the frequency.

The housing is sealed

Next, the housing is sealed. There are several methods for this. The “Seam Seal” method is often used. In this process, the metal lid and packaging are welded together with electrodes. Find out more about this topic in this blog post.

The final stages

The quartzes are marked with the help of lasers or special inks before they are subjected to final testing, packing and shipping.

Now the quartz crystal is finished and it can be mounted on the plate.
