Everything You Need to Know About Ferrite Beads As noted in my previous blog regarding PDS design, the whole power supply conundrum is one that has been plagued over the years with a number of erroneous rules-of-thumb; “black magic” design rules and confusion as to what does or doesn’t work. One of the most controversial topic areas focuses on the use of ferrite beads as a means of controlling and containing EMI. There is conflicting information concerning the use of ferrite beads and it is 阅读文章

The Art of Selecting Connectors Connectors are the unsung stars of both a product and its hardware development. Any Apple user knows the romantic tale the company has spun from infatuation with the first magnetic power connector through the betrayal of the 3.5mm jack to today’s ‘it’s complicated’ status thanks to the baggage their dongles create in pursuit of beauty. Product developers have similar emotional experiences with their prototypes. An unreliable connector that has 阅读文章

How To Design the Perfect PCB Stack Up With Altium Designer In the last 20+ years, electronics have become increasingly more complex. Board density is always being pushed to the limits, EMC/EMI regulations evolved and got stricter, and edge rates have become smaller. Therefore, the PCB Layout engineer needs a good understanding of EMC, PDN, EMI, and SI in order to route a modern PCB with confidence. In this article we’ll talk about some of the considerations we should have in order to create a PCB stackup 阅读文章

PCIE布局和布线指南小时候，拆开计算机，看着布满各种卡槽、芯片和其他电子器件的复杂主板，我总是有一个疑问，谁能把这些乱糟糟的东西搞清楚？随着我对计算机结构以及外围设备PCB设计的了解越来越多，我开始领会到PCB设计人员在致力于构建出色电子设备方面所做出的贡献。现代GPU，USB，音频和网卡都运行在同一计算机外围设备架构（PCI Express）的背面。如果您刚接触PCIe设备的PCB设计，会发现有关这一主题的信息是零碎的，其中一些信息甚至作为公司机密受到严密保护。幸运的是，基本规范可以拆解为可执行的设计规则。您可以使用合适的PCB设计软件，轻松地为下一个PCIe设备进行布局和布线。线路布线规范与大多数高速设备相比，三代PCIe均允许使用更长的走线长度。对于不同的数据传输速率，每一代都有其自己的阻抗和最大走线长度规范，为了达到并维持所需的性能，应严格遵循这些规范。确切的布线规范取决于您在设计中使用的是第几代PCIe。第1代和第2代中的走线长度均允许RX和TX信号走线的长度达到21英寸阅读文章

Multi-Board Design Basics Webinar - August 2018 The webinar touches on electrical and mechanical challenges of system and product level multi-board PCB design. A demonstration follows, showing how to mitigate the challenges of the PCB design process with the capabilities of Altium Designer. You need to manage the whole system connections, resolve conflicts, and update system-child projects. Coordinating separate board rotation, alignment, and enclosure fit is like a game of three-dimensional 下载PDF

Creating a Ground Plane for Your PCB Design It used to be that printed circuit boards seemed to have the same basic layer configuration, or at least that’s the way I tend to remember it. This meant that they were usually six layer multi-layer boards, with a ground plane and a VCC plane. The old CAD systems didn’t really have the ability to do much with power planes except to designate layers as a bottom layer or the like. The most you would see in them would be some “X’s” where there was 阅读文章

Altium Designer® 18: Key Benefits of ActiveBOM If you were unable to attend the July 19th live ActiveBOM^® webinar, you can view the the presentation slides and video recording at your convenience. If you prefer, you can also review the summary below for the session highlights. I briefly discussed some of the challenges design engineers encounter as they search for, select and source parts for designs. Then, I introduced ActiveBOM and provided a demonstration, followed by a summary and Q&A 下载PDF

Designing to Meet a Target BOM Price and PCB Cost Estimate Creating an accurate PCB cost estimate for design, components, production, assembly, shipping, and even firmware can be challenging tasks for new designers. Even established organizations can have trouble getting it right as it's hard to anticipate every problem that can arise during a design. Manufacturers can help you handle the production and assembly portion of a project, but any time a new design needs to be put into production, components 阅读文章

Manufacturing Checklists and Tools When it comes to manufacturing, organization is critical. With so many different players involved in the design process (engineers, sourcing agents, manufacturers, etc.), maintaining documentation and utilizing checklists and other tools will keep everyone on the same page and avoid confusion. Additionally, checklists can help ensure that the PCB design is fully complete and ready to send for manufacturing, protecting you from any unexpected 下载PDF

How to Generate Gerber Files in Altium Designer Step-by-Step Once you've got your PCB layout finished and you're ready to start preparing for manufacturing, one of the critical steps is to generate Gerber files. These files are used by PCB manufacturers to prepare stencils for photoresist exposure and subsequent etching. When you're ready to create your Gerber files, you need the right set of CAM tools that can take data from your PCB layout. Altium Designer helps make the process for generating Gerber 阅读文章

Preventing Ground Loops in Your PCB Design I think we’ve all been there. You buy that awesome stereo system only to hear that familiar humming sound in the background. When you take it back to the store the clerk blames the manufacturer. What components are to be considered a problem? The decoupling capacitor or ground wire? How about the bypass capacitor or ground loop interference? The stereo manufacturer will blame the component manufacturer and the component manufacturer can’t blame 阅读文章

Understanding Ground Planes in Your Two-Layer PCB Back when I was a young and hungry grad student, my first PCB ground plane design was used to collect analog signals from several sensors. When looking at a voltage graph of my measurements, the noise level was horrible and completely masked the signal I was trying to measure. I soon realized that I had completely bungled my ground plane connections, and ground loops were ruining my signals. Placing your ground plane and routing to ground are two 阅读文章

Better PCB Routing - Highlight Nets Regardless how many PCBs I design, I always find myself having to regularly review network paths on schematics layer and trace routes on PCBs. The complexity reminds me of a maze where only one path is the right one for a particular network. It is imperative that all the connections are accurate as errors made here will come back to haunt you later in the form of redesigns. The best way to ensure network accuracy is by isolating it so that each 阅读文章
