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.

Using Version Control in Your PCB Project Webinar

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).

Best Practices for Sharing PCB Files vs. Sharing PCB Projects

Even though today’s cloud platforms are immaculately secure and they allow a range of files to be easily shared, there are times where you should limit the data you’re sharing to only the critical files required. For PCB designers, this means either sharing entire design projects or sharing individual files with your manufacturer, customers, contractors, or collaborators. If you want to eliminate liabilities and keep your team’s design data secure, consider these best practices for sharing PCB design data with Altium 365.

If you’re a newer designer and you’re wondering whether reference designs are right for your next project, follow these best practices so that you don’t make any mistakes with your reference design.

PCB Via Size and Pad Size Guidelines

There are some aspects of PCB design and layout that seem deceptively simple, and yet they have a complex answer that is related to many important aspects of manufacturing. One of these design aspects is the match between PCB via size and pad size. Obviously, these two points are related; all vias have a landing pad that supports the via and provides a place to route traces into a via pad. However, there are some important sizing guidelines to follow when the matching pad and via sizes, and this match is an important element of DFM and reliability.

If you need to choose your own materials, follow the tips below to help you narrow down to the right material set.

When to Use Tented Vias in Your PCB Layout

There are some guidelines I see many designers implement as a standard practice, often without thinking about it. Some of these practices are misunderstood or implemented without best practices. Others are implemented without thinking about the potential problems. One of these is the use of tented vias, which is sometimes implemented in a PCB layout by default. Is this always the right practice?

How to Impedance Match and Terminate Capacitive Loads

The idea of a purely capacitive load is something of a fallacy.

Let’s take a look at this important aspect of interconnect design and see what it really means to terminate a capacitive load.

Meeting Standards: IPC 6012 Class 3 Annular Ring

Designers often conflate leftover annular ring and pad sizes - they need to place a sufficiently large pad size on the surface layer to ensure that the annular ring that is leftover during fabrication will be large enough. As long as the annular ring is sufficiently large, the drill hit will not be considered defective and the board will have passed inspection. In this article, I'll discuss the limits on IPC-6012 Class 3 annular rings as these are a standard fabrication requirement for high-reliability rigid PCBs.

Decoding PCB Fabrication Notes

Sending a board out for fabrication is an exciting and nerve-wracking moment. Why not just give your fabricator your design files and let them figure it out? There are a few reasons for this, but it means the responsibility comes back to you as the designer to produce manufacturing files and documentation for your PCB. It’s actually quite simple if you have the right design tools. We’ll look at how you can do this inside your PCB layout and how this will help you quickly generate data for your manufacturer.

Design Basics for HDI and the HDI PCB Manufacturing Process

As the world of technology has evolved, so has the need to pack more capabilities into smaller packages.
