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.

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.

Best Practices for Using Reference Designs

Best component companies will release reference designs for their new and legacy products to show designers an example application for a component. If the reference design is good enough and it very nicely illustrates how to quickly engineer around a few main components, I’m likely to use them in the design and the component maker has just earned my business. 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.

Your Complete Guide to Via Stub Analysis

Via stubs are sometimes viewed as an annoyance, especially when you only need to make a transition between adjacent layers. For low speed, less-dense boards with low layer count, via stubs are an afterthought, or they may not receive consideration at all. For faster edge rates/higher frequencies, the conventional wisdom is to remove all via stubs. The question is: what exactly counts as “high frequency,” and how do you figure out the relevant length?

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?

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.

Analyzing Crosstalk on FIFO and DDR4 Parallel Bus Interfaces

High-speed buses, whether single-ended or differential, can experience any number of signal integrity problems. A primary problem created by propagating signals is crosstalk, where a signal superimposes itself on a nearby trace. The industry-standard PCB design tools in Altium Designer® already include a post-layout simulator for examining crosstalk. Still, you can speed up crosstalk analysis in parallel buses when you use a powerful field solver.

Amplifier Stability at High Frequencies and Stray Capacitance

Any time-dependent physical system with feedback and gain has conditions under which the system will reach stable behavior. Amplifier stability extends these concepts to amplifiers, where the system output can grow to an undesired saturated state due to unintended feedback. If you use the right design and simulation tools, you can easily account for potential instability in your circuit models before you create your layout.

Working with Design Variants

The concept of design variants entails taking a single PCB design, and then on the assembly side, modifying specific components used in the design. Either by not installing, not installing, or choosing alternate components as replacements on a specific assembly to ultimately create different end products. In that way, you could support multiple product lines. This article describes the approach to working with variants.

How Copper Foil Roughness Affects Your Signals and Impedance

The history of engineering, both electrical and mechanical, is littered with approximations that have fallen by the wayside. These approximations worked well for a time and helped advance technology significantly over the decades. However, any model has limits on its applicability, and the typical RLCG transmission line model and frequency-independent impedance equations are no different. Copper foil roughness modeling and related transmission line impedance simulations are just one of many areas in which standard models cannot correctly treat signal behavior.

What is Burn-in Testing for Electronics?

Once you’re planning for production of any new board, you’ll likely be planning a battery of tests for your new product. These tests often focus on functionality and, for high speed/high frequency boards, signal/power integrity. However, you may intend for your product to operate for an extreme period of time, and you’ll need some data to reliably place a lower limit on your product’s lifetime. In addition to in-circuit tests, functional tests, and possibly mechanical tests, the components and boards themselves can benefit from burn-in testing.

How to Perform Differential Pair Tuning in Altium Designer 20

In order to properly suppress common-mode noise, differential pairs must be routed in parallel, with perfect symmetry, and with matched lengths. In real PCBs, meeting these three objectives isn’t always possible. Instead of eyeing out your different pair lengths, the interactive routing tools in Altium Designer make differential pair length matching easy. You can encode permissible length mismatches as design rules as part of controlled impedance routing, or you can manually perform differential pair tuning using a variety of meandering styles. Here’s how this works in Altium Designer.
