The Mysterious 50 Ohm Impedance: Where It Came From and Why We Use It

When we talk about S-parameters, impedance matching, transmission lines, and other fundamental concepts in RF/high-speed PCB design, the concept of 50 Ohm impedance comes up over and over. Look through signaling standards, component datasheets, application notes, and design guidelines on the internet; this is one impedance value that comes up repeatedly. So where did the 50 Ohm impedance standard come from and why is it important?

Keeping Your Circuits Dry

For the home hobbyist, protecting their electrical devices usually means keeping the coffee cup or soda can away from anything that carries a large voltage. Good practice indicates that electrical devices should be housed in an enclosure to protect expensive components and reduce the risk of electric shocks from exposed circuitry. However, what do you do if the fantastic new device you’ve designed needs to work in a humid, damp, or dripping wet environment?

Tips for Updating Old PCB Designs with New Parts

Have you ever opened up an old design and wondered how much of it was still usable? Maybe you were contacted by an old client, and they want you to provide some updates on an old design. No matter what the situation is, there are times where updating old PCB designs with new parts makes sense. If done correctly and when armed with all the right information up front, you can cut down the total design time while preserving the best parts of your design in a new iteration. Here’s what you can do to update your old designs successfully and how your PCB design features can help.

Managing PCB Manufacturing Quality Control in the Cloud

Anytime you’re looking for a fabricator to produce your new design, you should ensure they have a robust quality control program. Where can quality defects arise and how can manufacturers quickly get this information back to a design team? Sometimes emails can leave too much ambiguity and it is difficult to track progress on specific design changes in the PCB layout. If you’re planning to put a new design into high volume production, there are some basic points that should be checked during fabrication and assembly as part of a PCB manufacturing quality control program.

Controlling Crosstalk In Connector Pinouts

Controlling crosstalk is one of the key goals in any PCB design. In most instances, when we talk about crosstalk, it’s in reference to the unwanted interaction of the electromagnetic field traveling on one transmission line with a neighboring transmission line. But crosstalk can also occur in the connector pin out. This article will describe this type of crosstalk, the types of disruptions it causes, wherein the design cycle it needs to be factored in and how it can be successfully controlled.

The IEEE P370 Standard for High Speed PCB Interconnects

High speed PCB interconnects have continued to remain an active challenge in modeling and simulation, particularly when dealing with broadband signals. The IEEE P370 standard is a step towards addressing the challenges faced by many designers in determining broadband S-parameters for high speed structures up to 50 GHz. Although this standard has been in the works since 2015, it finally passed board approval and appears as an active draft standard.

DDR5 vs. DDR6: Here's What to Expect in RAM Modules

Modern digital systems throw the digital electronics textbooks out the window, and high-speed DDR memories are a perfect example of the paradigm shift that occurs when you jump into IC and PCB design. With DDR5 still being finalized, and DDR6 now being discussed, designers who are already comfortable with DDR4 will need to consider how their design practices should adjust to accommodate the constant doubling of data speeds in these high-speed memory technologies.

Making the Most of Your Crystal Oscillator

In my experience, the somewhat vague information you might find in a typical crystal datasheet doesn’t enable an engineer to be wholly confident that their design expectations can be met. On the other hand, “blindly” adopting what the crystal datasheet says usually results in adequate frequency stability. If you want to get inside and uncover what is going on, you need to start thinking about the crystal as a phase-shifting network.

Using Output Job Files for Rapid, Repeatable PCB Manufacturing Data Generation

An OutJob is simply a pre-configured set of outputs. Each output is configured with its own settings and its own output format, for example, output to a file or to a printer. OutJobs are very flexible – they can include as many or as few outputs as required and any number of OutJobs can be included in a project. The best approach is to use one OutJob to configure all outputs required for each specific type of output being generated from the project.

How Antipads Affect Signal Integrity in Your Multilayer PCB

Antipads on vias and landing pads are a point of contention in modern PCB design, and the debate around the use of these elements in a multilayer PCB is framed as a binary choice. Like thermal reliefs, ground plane splits, and orthogonal routing, the debate around antipads on landing pads and vias is framed as an always/never choice. With today’s modern PCBs, it pays to understand the effects of antipads on signal integrity.

How to Design a Microstrip to Waveguide Transition

RF structures can be complicated to design and layout, particularly because many RF systems lead double lives as digital systems. Getting an analog signal out of a component and into a waveguide for high isolation routing is not so simple as placing a microstrip or stripline coming off your source component. Instead, you need to create a special microstrip to waveguide transition structure to ensure strong coupling into and out of your waveguide.

Migrating Data From Other Version Control Systems

The development of electronic devices always involves the release of many different types of files. And these files are not static - they change as the project progresses.

Quarter-Wave Transformer Design For Real and Reactive Loads

RF systems operate with specific impedance values across entire interconnects, including on PCBs. Not all RF components are packaged in integrated circuits with defined impedances, so impedance matching circuits and line sections are needed to ensure signal transmission between different sections of an interconnect. One of these impedance matching techniques is the quarter-wave impedance transformer, which can be implemented as a printed trace with specific impedance.

RF Signal Chain and Link Budget Basics

If you're designing a wireless IoT device, and you know how to calculate the link budget, you can reasonably estimate whether your signal will reach its destination and be read by the receiver. To calculate the link budget, the designer needs to know something about all other sources of gain and loss in the system. Once link budget is determined, the designer can judge whether some modification is needed in their RF signal chain.

Best Methods for Calculating SMD Pad Size in PCB Design

SMD components require precisely sized pads for soldering during assembly. The designer is responsible for ensuring pad sizes are correct, either by calculating them and comparing with footprint data, looking through datasheets, or by memorizing SMD pad size standards. If you have a component and you don't have access to the footprint, and you decide to biuld the footprint yourself, what resources are available to ensure you have the correct pad size?

Can You Fix a Warped PCB?

Before we get too deep into this article, I’ll give you the simple answer. You probably can’t fix warping in your PCB after it’s already been fabricated.

We’ll run over some of these points in this article, and I’ll examine some points that might help you recover a warped board.
