Being able to design a board in your ECAD environment doesn’t mean that it is manufacturable in real life. You have to make sure your CAD representation won’t have any problems in the real world by taking some precautions. For example, there are certain areas that need to be free of components and have specified clearances like your board edge. This webinar will help you get acquainted with the creation and modification of your board shape so that you can ensure manufacturability.

There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.

During this year's AltiumLive CONNECT event, I recall receiving an interesting question about the skin effect and the distribution of current due to the presence of ground in coplanar transmission lines. In this article, we'll look at the electric field around a transmission line carrying a signal, and how this might be impacted by the skin effect.

When you get your PCBA back from an assembler, you’ll notice the packaging materials used to pack and ship the PCBA. Those materials are specific to electronics, and if you build products on behalf of clients, it’s important to know the packaging materials used for packing and shipping electronics. In this article I’ll show the main set of materials and equipment used to package electronics assemblies.

Once you've got your PCB layout finished and you're ready to start preparing for manufacturing, one of the critical steps is to create PCB Gerber files. When you're ready to create your Gerber files, you need the right set of CAM processor tools that can take data from your PCB layout. In this article, we'll guide you through this process of how to make PCB Gerber files and show some example tasks you might need to perform to generate them.

There are many aspects to designing a PCB. One of the larger aspects has to do with managing your components. We all need components for our designs, but are those components in our library and designs up-to-date or even purchasable? These questions need to be answered before we can safely use them. Altium Designer® has several tools to help you manage the components in your libraries and designs.

One of the major factors impacting reliability of a PCBA is the use of teardrops on traces in the PCB. Like many aspects of reliability, the considerations also span into the signal integrity domain, particularly as more high-reliability products require greater data handling capabilities and run at higher speeds. In this article, I’ll break down the issues present in teardrop usage on differential pairs and how these may affect impedance.

High-reliability electronics must go through multiple rounds of testing and qualification to ensure they can withstand their intended operating environment. Designing to performance standards, whether the baseline IPC standards or more stringent industry standards, is the first step in ensuring a reliable circuit board. In this e-book, readers will gain a thorough look into PCB testing and analysis, starting from basic tests performed on bare boards and completed assemblies.

Coupling capacitors find plenty of uses in analog applications and on differential protocols, acting essentially as high pass filters that remove DC bias carried seen on a signal. In the case of PCIe, there are a few reasons to place AC coupling capacitors on differential pairs beyond the fact that AC coupling capacitors are listed in the standard. In this article, we’ll look briefly at where to place coupling capacitors on PCIe links, as well as the reasons these are placed on PCIe links.

We are happy to announce that the Altium Designer 22.7 update is now available. Altium Designer 22.7 continues to focus on improving the user experience, as well as performance and stability of the software, based on feedback from our users. Check out the key new features in the What's New section on the left side of this window!

Some manufacturers have very convenient PCB manufacturing cost estimation calculators you can use, but the real costs depend on a number of factors. If you’re an entrepreneur and you’re producing your own boards, or you are managing manufacturing, testing, and delivery for a new project, it’s your job to help clients understand the primary cost drivers for new boards. Here’s how you can get an estimate of your fabrication costs, both for local and overseas manufacturers.

Selecting a connector is as much an art as it is a science. The artistic side is all about aesthetics and satisfying clearances, while the scientific side is all about signal integrity. For PCB mountable connectors, you’ll need to choose between surface-mounted or through-hole connectors, and you’ll need to consider how each type affects signal integrity in your application. Here’s what you need to think about beyond the standard connector specifications.

Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool.

There is a saying in copper pour PCB design, “Copper is free.” It means a PCB editor designer must think in reverse. A board starts off as solid copper, and the copper you don’t want is removed. It is faster to build, less consumptive, and less expensive to make a board that is mostly copper as compared to the same size board that is mostly bare. Picking the correct technique will make the difference between an effortless or frustrating experience.

What’s the key to designing a board that’s realistic on paper and in physical form? Let’s explore the top 5 design guidelines that you need to know to design your next manufacturable, functional and reliable PCB.

Highlighting nets will help you simplify your schematic and PCB design. In Altium , there are multiple options that enable you to leverage this capability to simplify the verification of connections and circuit paths and make sure that the design you send to your manufacturer accurately reflects the printed circuit board you need built.

The grid system in a printed circuit board design CAD system really is your friend, and if you haven’t taken the time to get properly introduced yet let me help you with that.

Whether you have a slew of PCBs to mass produce for your customers or a handful of project boards you wish to prototype all in one simple swoop, panelization is an effective way to bring high amounts of efficiency to your production.

Before you jump into the software, you should know the types of things you’re going to want to look out for. Traces, connection lines, differential pair routing, and route paths can all affect the routing process of your board. Make sure that you’re equipped knowing, ultimately, what you want your board design to accomplish and furthermore, where you anticipate potential problem areas to be.


Crosstalk on your PCB layout can be disastrous. If not corrected, crosstalk can cause your finished circuit board to either not work at all, or it may be plagued by intermittent problems. Let’s take a look at what crosstalk is and what you can do to prevent it.

EDA tools have come a long way since the advent of personal computing. Now advanced routing features like auto-routers, interactive routing, length tuning, and pin-swapping are helping designers stay productive, especially as device and trace densities increase. Read full article in our blog:
