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

This Semi-Additive Process is an additional tool in the PCB fabricators' toolbox that enables them to provide feature sizes for trace width and spacing that are 25 microns, (1 mil) and below depending on the fabricators' imaging equipment. This provides much more flexibility to breakout out tight BGA areas and the ability to shrink overall circuit size and/ or reduce the number of circuit layers in the design. As the PCB design community embraces the benefits of this new printed circuit board fabrication technique, there are of course many questions to be answered.
It’s no secret that component shortages have become more frequent this year. In fact, countries around the world are losing billions in revenue due to supply issues. Having the right components on hand is more crucial than ever as availability, obsolescence, counterfeit products and environmental non-compliance risks continue to grow. Fortunately, many shortages can be avoided by introducing proactive supply chain practices.
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:
We understand that many of you, like ourselves, have transitioned to working remotely. This process comes with its challenges and we would like to offer all and any help we can to minimize disruptions for your teams and business.
