大自然就像石英晶振一样,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体作为晶体振荡器。这篇博客文章将解释这是如何发生的过程。
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。
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。
将一块原始石英晶体转变成一个功能有源晶体振荡器需要几个步骤。我们一丝不苟地执行每一步,以确保最终的振荡器以最高的精度运行。
首先将原石英晶体切割并研磨成薄片。通常,它呈矩形或音叉状。由于其晶格,石英的切割影响其频率的稳定性。切割后,晶片进一步研磨和抛光,以达到所需的厚度和平行度。
石英晶片成型后,我们将其安装在两个电极之间,通常由金属制成。这些电极对于施加使石英振动的电压是必不可少的。石英和电极组件受到温度和湿度的保护,以保持频率稳定性。
封装的石英晶体现在是一个基本的晶体振荡器。然而,工程师在将其用于电子设备之前,必须对其精度进行测试。如果振荡器的频率关闭,我们可能需要稍微调整石英晶片的厚度。这个测试和调整过程一直持续到振荡器以可接受的稳定度工作在所需的频率。

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.
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.
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.
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.
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.
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.
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.
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.
