News & Updates

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.

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.

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?

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.

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.

The next stage in the evolution of mobile telephony is here with the roll-out of 5G. The designer looking to incorporate functionality to handle 5G signals into their circuits will face some challenging issues. So, what’s so special about 5G?

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.

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.

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.

Do you ever have to edit a large group of objects on your design? Whether you are dealing with your schematic or PCB, this webinar will help you get acquainted with the main tools for group editing of objects in Altium Designer. You will also learn how to effectively apply group editing methods with filters and selection tools in different design scopes.

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.

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!

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.

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.

Version control has been a staple of software development for decades, but hardware development can benefit just as much from a version control system (VCS). Traditionally, VCS has been managed locally tying you down to a workplace, but advances in cloud technology have removed that limitation. Learn how Altium 365 cloud technology enables working concurrently on designs with built-in version control and evaluate its advantages.

A schematic drawing will not only tell your PCB design software what needs to connect where, but it also communicates the purpose of a circuit to other people. It’s easy to create a schematic, but it can be harder to make a helpful schematic that can be quickly and easily read and comprehended by the reader. In this guide, based on years of industry experience, we will show you how to improve your schematic layout so that your designs are elegant and readable.

There are two basic reasons for designing a flex circuit into your product: to build a compact and efficiently assembled device, or to make the circuit dynamically integrated with the mechanical function of the product. You may, of course, lean on both of these reasons for justifying the use of flex circuits. On this note, let’s look at some rigid-flex PCB applications and design examples to see the issues that spring to mind when designing flex circuits

With Altium 365, you can grant permission to teams or users based on the specific needs of a project. We have expanded Altium 365’s file-sharing setting, giving you more granular control over who can download source files and reshare projects with others

Any time you design a PCB, and you want to turn it into a real product, you will have to make sure the design obeys the constraints within the standard PCB manufacturing process. This imposes multiple rules on any design, and ECAD software will enforce design rules as you create the board to ensure you obey these important constraints. Make sure you enforce the right design rules at the beginning of the PCB design workflow

High frequency PCB design can seem esoteric, and I've heard many an engineer describe it as "black magic"! The subject is also a bit confusing, especially once someone asks which frequencies could be reasonably considered "high". Before you do anything inside the layout for a high-speed or RF PCB, you will need to pay attention to the materials being used in the board. If you're unsure which high frequency PCB materials you should use, then keep reading to learn more.

Of all the noise and operational challenges designers face in their PCBs, there is one overarching problem that is arguably most popular: electronic noise. It could originate as an SI/PI problem, it could possibly arise from some external source, or it could be good old-fashioned crosstalk! These tend to fall into three categories: adding shielding, doing something to create isolation, or placing filters. Let's look at all of these as they tend to be the default solution set when confronted with many noise problems.

Rigid-flex in Altium Designer starts with designing a manufacturable PCB layer stack complete with via transitions and any calculated impedance requirements. Flex sections also need to be placed in the layer stack before moving into the PCB layout. Once inside the PCB editor, bending lines can be clearly defined in the PCB layout, and these can be visualized in Altium Designer's 3D PCB design tools. Keep reading to see how Altium Designer supports your flex and rigid-flex designs.

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.

During the recent IPC APEX expo, there was a lot of discussion about SAP, or semi-additive PCB processes. As with any new technology adoption there were people that are excited to jump right in and start designing with much finer feature sizes and work through the inevitable changes to the traditional thought process. Others are in a "let’s wait and see" mode and of course there are a few skeptics there as well, so keep reading to learn more.

Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms.

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.
