每天都会接到很多晶振客户的询盘,有的是工厂采购,有的是贸易商采购,有的是EMS代工厂采购员等等.每天都有上百个咨询石英晶振参数报价及拿货订货.也有很多客户经常会"一问三不知",什么是一问三不知,就是我们石英晶振销售人员口中经常说的参数,尺寸,封装.并不是每一个来咨询问料的客户都是能很清楚明白的知道晶振都有哪些参数.这也跟专业性有关吧,毕竟我们是专业做晶振这一块的,对于刚接触晶振的采购人员来说就是一个未知领域,就像我一样,我从事石英晶振销售三年有余,虽然说是从事电子行业的人员,但我却对其它电子产品”一概不知”.什么电容电阻二三极管,到现在为止我都还不知道他们到底长啥样.虽然客户发过来的电路板上是会有这些产品出现,但我却认不出来.只能从板子里认出晶振,然后估出大概尺寸,看出哪个品牌.我们公司从事晶振行业18年有余,一直坚守晶振行业这个领域的事业.现在给大家介绍一下<什么是晶振的具体参数>,<晶振的专业术语>.

Every day, I receive a lot of enquiries from crystal customers, some are factory procurement, some are traders, some are EMS foundry buyers, etc. Every day, there are hundreds of consulting quartz crystal parameters and get orders. Many customers often "One question, three don't know", what is one question, three, I don't know, it is the parameters, size, and packaging that we often say in the quartz crystal sales staff. Not every customer who consults can know clearly what crystals are. Parameters. This is also related to professionalism. After all, we are specialized in crystal oscillators. It is an unknown field for purchasers who are just in contact with crystal oscillators. Like me, I have been engaged in the sales of quartz crystal oscillators for more than three years, although I am a person in the electronics industry, but I don’t know about other electronic products. I don’t know what capacitors and diodes are. So far, I don’t know how long they are. Although the customer’s board will be there. These products appear, but I can't recognize them. I can only recognize the crystal oscillator from the board, and then estimate the approximate size to see which brand. Our company is engaged in crystal oscillators. More than 18 years, we remain firmly committed to the cause of the crystal industry in this area and now tell you about .

首先就是我们经常有问到的,标准频率以及频率偏差也称之为精度.(Nominal Frequency and Tolerance)

The first is what we often ask. Standard frequency and frequency deviation are also called accuracy. (Nominal Frequency and Tolerance)

在正确的振荡线路匹配下,从振荡线路输出的频率称之为”公称频率”.石英晶体谐振器的频率通常都是以兆赫兹(MHZ)或者千赫兹(KHZ)来表示.而频率偏差则是在实际批量生产及振荡线路应用上,产品在室内环境25度中都会有一些相对于中心频率的频率误差.这一类的频率容许误差的最大散布值,一般是有ppm(parts per million)或者%(percent)来表示.

Under the correct oscillating line matching, the frequency output from the oscillating line is called the “nominal frequency.” The frequency of the quartz crystal resonator is usually expressed in megahertz (MHZ) or kilohertz (KHZ). The frequency deviation is In actual mass production and oscillating line applications, the product will have some frequency error relative to the center frequency in the indoor environment of 25 degrees. The maximum dispersion value of this type of frequency tolerance is generally ppm (parts per million). Or %(percent) to indicate.

其次就是石英晶振的基本波振荡和倍频振荡模态简称”泛音振动”. (Fundamental and Overtone Vibrations Mode)

The second is the fundamental wave oscillation of the quartz crystal oscillator and the frequency doubling oscillation mode referred to as "overtone vibration". (Fundamental and Overtone Vibrations Mode)

AT切割型的石英晶振主要以厚度剪切振荡模式存在,高次谐振动波与电极区域之间的基本振动共存.由于两个电极的极性相反,在压电石英晶体谐振器中只能激发奇数谐波振动.

The AT-cut quartz crystal oscillator mainly exists in the thickness shear oscillation mode, and the high-order harmonic vibration wave coexists with the basic vibration between the electrode regions. Since the polarities of the two electrodes are opposite, only the piezoelectric quartz crystal resonator can be excited. Odd harmonic vibration.

再然后就是相当主要的负载电容了(Load capacitance),负载电容CL是振荡器通过谐振器两端观察电路时所呈现出的电容量,负载电容形式上与谐振器串联或者并联,对于并联负载情况,CL的存在将影响并联谐振频率,而并联负载谐振频率FL由下面工式给出,所以在咨询型号参数的时候,这个参数必需是客户指定参数.

Then there is a fairly large load capacitance. The load capacitance CL is the capacitance that the oscillator exhibits when observing the circuit through the resonator. The load capacitance is in series or parallel with the resonator. For parallel load conditions. The presence of CL will affect the parallel resonant frequency, and the parallel load resonant frequency FL is given by the following equation, so when consulting the model parameters, this parameter must be the customer-specified parameter.

在晶振购买过程中，这些参数都是用得较多的几个参数了.其实还有很多参数还没介绍完,明日再继续更新最新的晶振参数说明.希望可以帮助那些想要了解晶振,并且采购晶振的客户去了解更多的信息资料.

世界上第一块石英表的实际应用与音叉石英晶振的开发是不少工程师所流下的血液，汗水以及眼泪的结晶.随着时间慢慢的推移,石英晶振产品不断的连接着电视,电脑,手机,手表等慢慢靠近着我们的生活.渐渐的这些石英晶振产品已发展成电子行业不可或缺的固定产品.甚至被称为”工业之盐”,电子产品的”心脏”.这些石英晶振最早主由EPSON TOYOCOM公司生产制作而成.

The practical application of the world's first quartz watch and the development of the tuning fork quartz crystal oscillator are the crystallization of blood, sweat and tears that many engineers shed. As time goes by, quartz crystal products are continuously connected to TVs and computers. Mobile phones, watches, etc. are slowly approaching our lives. Gradually these quartz crystal products have developed into indispensable fixed products for the electronics industry. They are even called "the salt of industry", the "heart" of electronic products. These quartz crystal oscillators The earliest production was produced by EPSON TOYOCOM.

QMEMS(Quartz+”MEMS”)是促进MEMS(微电子机械系统)晶体材料微加工工艺独特技术的名称,是EPSON TOYOCOM公司产品的主要核心技术.通过充分利用这项技术的优势可以为石英晶体器件实现更小巧的尺寸及更好的性能.QMEMS技术的起源可以追溯到20世纪70年代初.

QMEMS (Quartz+ "MEMS") is the name of a unique technology that promotes micromachining of MEMS (micro-electro-mechanical systems) crystal materials. It is the main core technology of EPSON TOYOCOM. By taking advantage of this technology, it can be realized for quartz crystal devices. Smaller size and better performance. The origins of QMEMS technology can be traced back to the early 1970s.

1969年，在日本中部的苏瓦湖岸边，当地的一家公司悄然成功地将世界上第一块石英晶振手表变成了现实 - “精工石英天文35Q”（图1），这一事件让世界措手不及。

In 1969, on the shores of Lake Suva in central Japan, a local company quietly succeeded in turning the world's first quartz watch into reality - "Seiko Quartz Astronomy 35Q" (Figure 1), an event that caught the world off guard. .

这真是一个划时代的突破。在此之前，石英钟表虽然非常精确，但却非常大，以至于不能轻易携带，而是采用箱形钟表的形式悬挂在墙壁上。虽然机械手表当然已经存在，但这些并不精确。需要一个创新的解决方案来解决更好的精度和更紧凑的尺寸的双重问题，全球各地的公司都在1960年代中后期进行无情竞争以找到一个问题。

This is really an epoch-making breakthrough. Prior to this, quartz clocks, although very precise, were so large that they could not be easily carried, but were suspended from the wall in the form of a box-shaped clock. Although mechanical watches certainly exist, these are not precise. An innovative solution is needed to solve the double problem of better precision and more compact size, and companies around the world have ruthlessly competed in the mid to late 1960s to find a problem.

在Quartz Astron到来之前实际使用的晶体单元
类型的一个例子。虽然看起来很大，长约50毫
米，但它实际上是当时最小的水晶单元之一.

它是精工苏瓦株式会社，苏瓦湖岸边，它正悄悄地控制着这个发展的竞争对手。使精工苏瓦株式会社领先其竞争对手的因素之一是该公司成功地使晶体单元更加紧凑。传统的水晶装置尺寸非常大，无法装入手表般小的东西（图2）。精工苏瓦株式会社通过采用称为“音叉晶体”的新结构解决了这个问题。新开发的'Cal.35SQ'型尺寸*晶体单元的直径为4.3mm×长度为18.5mm（图3）。此外，精工苏瓦株式会社还能够调整水晶单元的内部结构，以便克服腕表连接在佩戴者手腕上时经常受到的振动和撞击所引起的问题。

It is Seiko Suva Co., on the shores of Lake Suva, and it is quietly controlling this growing competitor. One of the factors that led Seiko Suva to lead its competitors was the company's success in making crystal units more compact. The traditional crystal device is very large in size and cannot be loaded into a watch-like thing (Fig. 2). Seiko Suva solved this problem by adopting a new structure called "tuning fork crystal". The newly developed 'Cal.35SQ' size* crystal unit has a diameter of 4.3 mm and a length of 18.5 mm (Fig. 3). In addition, Seiko Suva can adjust the internal structure of the crystal unit to overcome the problems caused by vibrations and impacts that are often encountered when the watch is attached to the wearer's wrist.

*此时公司开发的音叉式水晶单元用于Suwa Seikosha内部制造的手表。因此，“我们没有给他们一个特定的产品型号，只是通过他们的机芯名称或手表的操作机制（Calibre，或'Cal。'）来提及它们，”Mutsumi Negita说。

* At this time, the company's tuning fork crystal unit was used for watches made inside Suwa Seikosha. Therefore, "we didn't give them a specific product model, just mention them by their movement name or the operating mechanism of the watch (Calibre, or 'Cal.')," Mutsumi Negita said.

采用新开发的音叉结构，使Suwa Seikosha能够成功制造出更小的晶体单元，半径仅为4.3mm，长度为18.5mm。它被分配了型号“Type Cal.35SQ”并且具有8.192kHz的正常频率。

Figure 3: Tuning fork crystal unit used in Quartz Astron
With the newly developed tuning fork structure, Suwa Seikosha was able to successfully manufacture smaller crystal units with a radius of only 4.3 mm and a length of 18.5 mm. It is assigned the model "Type Cal.35SQ" and has a normal frequency of 8.192 kHz.
