Stubs are an important topic in high-speed PCB design, and there is a longstanding guideline that stubs should always be removed from all vias on high-speed digital interconnects. While stubs are bad for high-speed lines, they do not always need to be removed. What is more important is to predict the loss profile and frequencies, and to floorplan appropriately to try and prevent such losses.

Once you finish your placement and routing in your PCB layout, it can be tempting to wrap up the layout and send everything in directly to manufacturing. The reality is that the board may still need some work before it is considered finished. The cleanup you perform at the final stage of PCB layout will help you catch any outstanding errors that can't be programmed into your DRC engine, and it gives you a chance to add any outstanding details to the surface layers.

In this project we’ll be building a moderate sized LED panel on insulated metal substrate (IMS). This light panel has three different white balance High CRI LED types on it, warm, neutral and cool. By changing the brightness of the different white balances, the light from the panel can be adjusted to match other lighting, making it perfect for film use - but also creating perfect lighting for electronics work. As with all my projects, this LED panel is open source, you can find the Altium project files over on my GitHub released under the permissive MIT License.

Every design should begin with selecting the materials that will appear in the PCB stackup, as well as arranging layers in the stackup to support layout and routing. This section of our PCB manufacturing andc DFM crash course focuses on selecting the right materials for your PCB design. Materials should be selected given the particular design requirements outlined in your specifications.

FPGAs come in quad or BGA packages that can be difficult to floorplan, especially with the high number of I/Os often implemented in these components. FPGAs offer a lot of advantages in terms of their reconfigurability, but they can require a lot of effort to layout and route without headaches. If you’ve never worked with an FPGA in your PCB layout, we have some guidelines that can help you get started.

S-parameters are fundamental quantities in signal integrity, and an ability to understand them from measurement or analysis is very important. If you have a 3-port network, like a power divider or circulator, it may appear that you must use a 3-port VNA to measure these S-parameters. It is always acceptable to measure between two ports, but you need to know what exactly it is you are measuring. In this article, we’ll look at the relationship between the true 3-port S-parameters with a 2-port measurement.

Before implementing design for manufacturing, it is important to understand the underlying process behind producing a physical PCB. Regardless of the various technologies present in each facility, a large majority of industry-leading manufacturers follow a specific set of steps to turn your design from a drawing in a CAD application into a physical board. In this article, we'll cover the basics that designers need to know as part of our crash course series on PCB manufacturing.

If you compile a list of skew sources, you'll see that fiber weave-induced skew is only one entry on a long list of skew sources. We'll look at this list of possible skew sources below, and we'll see how they affect the operation of your PCB. From the list below, we'll see that some of these issues with skew are not simply solved by paying attention to the fiber weave construction in a PCB substrate.

This track is for the engineer who understands high-speed design requirements and wants to learn design practices to help ensure signal integrity and EMC with fast digital protocols, mixed-signal boards, and high layer counts.

We love answering questions from our readers and YouTube viewers, and one of the recent questions we received relates to EMI from switching elements in a switching regulator is "Should a cutout be placed below the inductor in a switching regulator circuit?". Despite the variations in inductors and their magnetic behavior, there are some general principles that can be used to judge the effects of placing ground near inductors in switching regulator circuits. We’ll look at some of these principles in this article
