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.

It's no secret that software developers often use completed code fragments from other projects for quick and predictable results. The same can be done for PCB Design, there is no need to spend time rewiring schematics or laying out components on boards you’ve done before. Join us this webinar where we’ll go over how you can use your existing designs to create reusable design blocks, speeding up the design cycle for your future projects.
