The Digital Engineer's Guide to RF PCB Layout and Routing

With modern systems running at higher frequencies, incorporating multiple wireless protocols, and interfacing with many analog sensors, advanced designs require knowledge from digital and RF design disciplines. If you’re now starting to work in the RF realm and you need to design an all-analog or mixed-signal system, RF PCB layout will need to become a new specialty. If you’re a digital designer and you’re now jumping into high-frequency analog design, keep reading to learn more about RF PCB layout and routing.

Microstrip Ground Clearance: How Close is Too Close?

If you take a look at any guidelines for controlled impedance traces, you’ll clearly see that the trace width is calculated without any ground pour near the trace. However, most designers will state that unused areas on each PCB layer should be filled in with grounded copper pour. If you bring some ground pour near a microstrip, you’ve now formed a coplanar waveguide arrangement. So now the question becomes, how much microstrip to ground clearance do you need to ensure you’ve hit your impedance goals?

PCB Layout Guidelines for Switching Power Supplies and Regulators

In this article, I want to briefly focus on how power supplies and regulators are different, although this should already be clear to most designers. For a power supply and for a PCB with an on-board regulator, the switching regulator layout will be a major determinant of overall system performance. Therefore, we’ll largely look at some layout guidelines for switching power supplies in terms of regulator layout.

PCB Sharing and What Data You Can Share in Altium 365

Altium 365 is giving design teams a new way to share and manage their design data. Most users are probably aware of project-level and component-level PCB sharing features, but sharing actually extends down to the level of individual files thanks to the managed content system within Altium 365. If you’ve ever wanted a single place to store and manage all of your design data, then Altium 365 is here to help you and your team stay organized.

How to Combat Power Supply EMI in Your PCB

Power supplies are one of those systems we all tend to take for granted. Everyone’s first task in power supply design is usually to ensure the voltage and current output reach the desired level, probably followed by thermal considerations. However, due to safety issues, EMC requirements, the use of higher PWM frequencies, and the need for smaller packaging, power supply EMI should be a major design consideration. With that being said, what are the major sources of power supply EMI, and how can power supply designers keep them in check?

Leveraging the Free Footprint Community to Design at Lightning Speed

Designing footprints is a job most people hate. It’s tedious, time-consuming, and doesn’t result in much except, well, a footprint. Companies now realize this pain point and offering designers free, well-designed PCB footprints. Why would they spend their time doing this? In this article, we’re going to review some of the free offerings that exist within the PCB design community. Once you’re armed with this information, you will spend most of your time designing and routing boards instead of pulling your hair out creating footprints all day.

Designing for Multiple PCBs in the Same Project

The majority of our PCB designs sit as a single PCB under our Altium Designer projects. It sometimes happens that we have a single project that requires multiple PCBs with various stuffing options, but when it happens, a lot of us tend to get stuck. How do you handle the exact change across both projects? How do you guarantee those changes to be identical? This article will review an approach to managing multiple PCB designs within a single project, ensuring your single source of truth.

All About Your PCB Trace Length: How Long is Too Long?

The maximum PCB trace length you can place between two components depends on multiple factors, such as signaling protocol, component specification, losses in PCB laminate, and skew. With all this in mind, let’s look at where losses accumulate along the channel.

Using an LDO vs. Switching Regulator in Your PCB

For low power devices, we generally see two types of power regulators: a low dropout regulator (LDO) or a switching regulator. You can mix and match these at different points along your power bus, but there’s still the matter of choosing whether to use an LDO vs. a switching regulator in your designs. If you’ve ever wondered how these decisions are made and when to use each type of regulator, just know that there is more to this decision than simply looking at the input/output voltage/current.

What They Don’t Teach You About Fluxes

PCB fabrication is an extremely complex technological topic that deserves recognition as the most fundamental part of PCB engineering. Unless connectors, conductive adhesive, wire-bonding, or zebra-tape are used, in the modern electronics industry it’s always necessary to use some kind of flux during the soldering process to create an electric connection. In this article, we’ll discuss fluxes — what they are, what they are made of (yes, there is going to be a lot of chemistry, don’t be scared), how they should be used, and in what direction the industry is going.

Thermal Management for Integrated Circuits

As anyone who designs and builds electronic devices knows, the device will generate heat when it’s switched on. Wherever current flows through an impedance, energy losses will manifest themselves as heat. Integrated circuit packaging is getting smaller to meet the trend for more compact devices but at the cost of poorer thermal properties. This article describes the basic thermal management approaches to consider in your next designs.

Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy

We continue to explore the magic of energy conversion in a PWM transducer. Why is it magic? Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with scissors, cuts the “fabric of energy” into pieces, and then, like a sewing machine, stitches the pieces of energy into a dress - DC Magnitude. What is a constant component and how can we get it? Let's explore!

Anatomy of Latitude Part One: Pulse Width Modulation (PWM) as a Result of the Evolution of Linear Systems

There are different techniques in the world of technology to achieve various goals, both final and intermediate. Some techniques are so successful that they are commonly used with high efficiency. Electronics is no exception. The greatest example is the use of Pulse Width Modulation (PWM) signals (energy), which is applied in any modern electronic device. To apply PWM effectively, it is necessary to understand the engineering difficulties that engineers faced in the past, and the thoughts and ideas that subsequently were combined into effective, complete PWM power solutions.

What Influences Electrolytic Capacitor Lifespan?

If you speak with a bunch of design engineers, you might quickly form the opinion that the electrolytic capacitor has a particularly dubious reputation. A faulty electrolyte mix used in these types of capacitors led to premature device failures, and quite often, a “bit of a mess” was made to the PCBs on which they were soldered. However, despite the problem of the capacitor plague, this article is focusing on helping the designer understand how to get many more years of useful life from an electrolytic capacitor.

Communicating PCB Layer Stackup Needs to Manufacturers

In the business of PCB design, communicating needs to manufacturers and vendors is a top priority. The context of our requests is sometimes lost either by not providing the correct information, not listing enough information, or not giving any information. Although the experienced PCB designer can take steps to specify everything they want to see in their PCB stackup, eventaully the manufacturer will handle that decision in an effort to balance available materials with processing capabilities and yield.

Ebook: PDN Simulation and Analysis Guide

Most designers don’t realize they need to worry about power integrity until they have a power integrity problem. Other designers might build boards that can’t handle the demands of modern digital and high frequency components, and they may not realize the problems that lurk in their power delivery network (PDN). Although the basic concepts involved in designing for power integrity are well-known, myths about power integrity abound, and designers need tools to help them evaluate and qualify power integrity in a PDN.

The use of ferrites in a PDN is one design recommendation that is fraught with unclear guidance and over-generalized recommendations.
