    希华时钟晶体振荡器提供领先全球的理想方案,随着各种高速串流资料讯号广泛使用,需要更高频的时脉讯号源,但传统机械(研磨)工法,已无法满足更高的频率需求,遂将半导体晶圆制程应用在石英晶片产业,使高频化、小型化、高精度振荡器产品得以实现,工法如下

    1.应用光蚀刻工法,可轻易在wafer状态(晶圆级)下,一批次将数万颗石英晶体振荡器完成厚度加工达到所需要的频率。

    2.同样应用光蚀刻工法,在wafer状态下,一批次将数万颗晶体振荡器完成晶片外型,且用光蚀刻法轻易将产品小型化,尺寸一致性更高,精度更好。

    3.接着用同样工法完成发振区电极回路。

    为什么要光刻?

    1.小型化
    (目前可至0806)
    采用半导体制程,满足客户小型化产品需求

    2.高频化
    (max500MHz)

    光蚀刻制程克服高频晶片技术障碍

    图22

    由于石英晶片机械加工极限厚度约30um (55MHz),所以更高频率晶片(一般指基本波60MHz以上),需采用光蚀刻制程克服技术障碍。
    * 石英晶片厚度越薄,晶体单元的频率越高,传统晶片采用机械加工厚度有局限性,最薄约30um(55MHz左右振荡频率)
    * 使用光蚀刻制程,可3D结构设计阶梯结构及凹槽结构,强化晶片刚性,让振荡区厚度不受局限,使产品更易小型化、高频化、特性更好。希华时钟晶体振荡器提供领先全球的理想方案.

    由于更高频率晶片厚度偏太薄,晶片刚性不够,使用光蚀刻制程,结构可阶梯结构3D化设计,让振荡区厚度不受局限,一般可达到3~30um的技术需求,如图示:

    领先全球HELE Quartz Crystal Oscillator编码详情[ 查看详情 ]

    领先全球HELE Quartz Crystal Oscillator编码详情,From Raw Quartz Crystal to Precision: Crystal Oscillators

    In the realm of electronics, precision is paramount. The accuracy of a device's operation often hinges on the stability of its frequency generation.

    Nature, like a quartz crystal, is essential in pursuing precision. Modern electronics use a quartz crystal found in nature as a crystal oscillator. This blog post will explain the process of how this happens.

    Understanding Quartz and Its Unique Properties

    Quartz is one of the most abundant minerals found on Earth. It's a semi-precious gemstone composed of silicon dioxide. Quartz crystals come in various types, including rock crystal, amethyst, citrine, rose quartz, smoky quartz, ametrine, jasper, carnelian, and agate. Beyond its aesthetic appeal, quartz has unique properties, making it a cornerstone of electronic devices.

    Applying mechanical stress to quartz generates an electric charge, and people call this property piezoelectricity. Crystal oscillators, which many devices use, rely on the special properties of quartz crystals.

    The Transformation Process

    Turning a piece of raw crystal quartz into a functional crystal oscillator involves several steps. We perform each step meticulously to ensure that the resultant oscillator functions with the highest possible precision.

    Cutting and Grinding

    Start by cutting and grinding the raw quartz crystal into a thin wafer. Typically, it takes the shape of a rectangle or a tuning fork. The cutting of quartz affects the stability of its frequency due to its crystal lattice. Once cut, the wafer is further ground and lapped to achieve the desired thickness and parallelism.

    Mounting and Encasing

    After shaping the quartz wafer, we mount it between two electrodes, usually made of metal. These electrodes are essential for applying the voltage that will cause the quartz to vibrate. The quartz and electrode assembly is protected from temperature and humidity to maintain frequency stability.

    Testing and Adjustment

    The encased quartz crystal is now a basic crystal oscillator. However, engineers must test it for precision before using it in an electronic device. If the oscillator's frequency is off, we may need to adjust the thickness of the quartz wafer slightly. This testing and adjustment process continues until the oscillator operates at the desired frequency with an acceptable level of stability.

    The Role of Quartz Oscillators in Electronics

    Quartz crystal oscillators have become indispensable in the world of electronics. When electricity powers the quartz crystal, it vibrates at its special frequency, generating a signal with an exact frequency. This signal stabilizes clock signals in digital circuits, stabilizes frequencies in radios, and keeps time in wristwatches.

    Quartz oscillators are everywhere, so you're probably always close to one, within a few feet, at any time. They exist in everything from cell phones and computers to car engines and satellite systems.

    In Conclusion

    From raw quartz crystal to electronic components, the journey combines nature and technology in a captivating way. It's a testament to human ingenuity that we've found ways to harness the unique properties of quartz for our purposes.

    We provide high-quality quartz crystal oscillators for different purposes at Harmony Electronics. We are excited to be a part of this journey.

    The accuracy of our products depends on the quality of the quartz crystal we use. It also depends on how carefully we make them. You can learn more about our commitment to quality and the role of quartz in our products here.

    When you use your phone or drive your car, think about the small piece of quartz. This small piece of quartz helps these devices work accurately. From raw quartz crystal to an indispensable part of modern electronics, it's truly a transformation journey.

    从原始石英晶体到精密:晶体振荡器

    在电子领域,精确度是最重要的。设备操作的准确性通常取决于其频率产生的稳定性。

    大自然就像石英晶体一样,在追求精确的过程中必不可少。现代电子学使用自然界中的石英晶振作为晶体振荡器。这篇博客文章将解释这是如何发生的过程。

    了解石英及其独特的属性

    石英是地球上发现的最丰富的矿物之一。这是一种由二氧化硅组成的半宝石。石英晶体有多种类型,包括水晶、紫水晶、黄水晶、玫瑰水晶、烟石英、水晶、碧玉、红玉髓和玛瑙。除了其美学吸引力,石英还具有独特的属性,使其成为电子设备的基石。领先全球HELE Quartz Crystal Oscillator编码详情.

    对石英施加机械应力会产生电荷,人们称这种性质为压电性。许多设备使用的晶体振荡器依赖于石英晶体的特殊性质。
