关于客户
Spectrum Integrity 是一家提供全方位服务的工程设计服务公司和解决方案提供商，为需要先进射频、高速和半导体测试应用的出色硬件设计的公司提供服务。该公司设计超高速数字、射频和微波 PCB，可处理频率为 20 至 110 GHz 及以上的信号。 CAD 屏幕截图显示了在 Altium Designer 中成功设计的 12 层和 14 层超高速数字应用。这些示例具有设计用于支持 50GHz 信号的外层走线和设计用于支持 28GHz 的多个内层走线。这些设计利用了复杂的几何形状、分离电源层、传输线和共面过孔，这些设计均通过 Altium Designer 和专有设计技术的组合成功设计。
挑战
Spectrum Integrity 是一家设计超高速数字、射频和微波 PCB 的公司，在设计过程中面临着重大挑战。该公司独特的设计要求需要专有的流程，但它也必须与行业标准组件库和客户的设计审查流程相连接。该公司依赖于一系列专用工具，但这些工具中的本机原理图功能无法使用。相反，Spectrum Integrity 必须使用第三方原理图工具，该工具无法实现布局和原理图的同步，并且缺乏交叉探测功能。这使得整个过程脱节。此外，电路板设计没有免费的外部查看器功能，也没有导出设计文件的简单方法。频繁的客户评论是一个乏味而漫长的过程。该公司曾尝试使用 PADS 简化流程，但其原理图捕获工具同样不足，而且其版本控制缺少关键的内置功能。
解决方案
Spectrum Integrity 采用 Altium Designer 来解决其设计挑战。 Altium Designer 提供的高级功能和跨设计流程的集成提供了立竿见影的改进。该公司发现可以轻松地针对复杂的 RF 设计定制 Altium Designer 环境。该工具套件中添加了战略性的专有改进，使其对于射频和超高速数字设计而言非常强大和高效。为了简化与 RF 分析的交互，电路板设计以 Gerber 数据形式导出到 3D 场解算器中。完成分析后，Altium Designer 以 AutoCAD 或 DXF 格式读回文件，这一过程在集成工具套件中保留了网络智能。 Altium Designer PCB 布局中的自动化有助于简化设计过程中的步骤。版本控制功能对于频谱完整性非常重要，因为射频设计通常需要在非常广泛的审查过程中延伸多个版本。 Altium Designer 还包括一个免费的设计查看器，可以导入和导出多种流行格式。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
