What is an Eye Diagram?

The eye diagram is a useful measurement or simulation as part of channel compliance. The measurement shows many different factors that can affect signal behavior simultaneously, ultimately allowing for qualification of errors and losses in a channel. In this article, I’ll run over some of the fundamental measurements that you could manually extract from an eye diagram and how they reveal some strategies for improving channel designs.

Beginner PCB Design Mistakes and How To Avoid Them

When starting out with PCB design, it’s common to treat the process as simply ‘connecting the dots’: as long as connections are made, it’s not particularly important how these connections are made. Having reviewed quite a number of PCBs of other PCB design engineers over the last few years, there are common, unfortunately erroneous, occurrences between a lot of them. This article aims to illustrate the top five beginner PCB design mistakes and what we can do to avoid making them. Let’s get started!

How to Select Copper Foil for High-Frequency PCB Design

The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss for products with RF applications. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen in TDR measurements. In this article, we'll look at the balance between copper foil losses and other types of losses in a PCB, as well as some strategies that are commonly used to overcome roughness.

What is Hybrid Beamforming?

In this article, we’ll look at beamforming implementation in an advanced method combining analog and digital techniques, known as hybrid beamforming. This method blends both digital and analog techniques to create multiple beams and thus reach multiple users with varying intensities.

Why Most Via Impedance Calculators Are Inaccurate

The problem with every via impedance calculator that I have seen is simple: they are incomplete or totally wrong. The “incomplete” part refers to a lack of context; these calculators can roughly reproduce a well-known estimate from a legend like Howard Johnson in his Digital Design textbooks. However, these calculators never provide insight into what they are actually calculating, or where the calculated via impedance is accurate. Keep reading to see why these calculators get it so wrong, as well as the context surrounding via impedance.

An Overview Of PCB Outer Layer Processing

Previously, I described the PCB fabrication operations relative to inner layer processing, lamination, drilling, and plating. The last step in the process is outer layer processing which is described below. Once the desired plated copper thickness of a PCB has been achieved, it’s necessary to etch away the copper between the features in order to define the outer layer pattern.

How Do Pads and Vias Impact Total Capacitor Parasitic Inductance?

There are many factors at play in determining the impact of inductance on high-frequency power distribution systems. Two topic areas, inductance of the decoupling capacitor and inductance of the power planes, were addressed in earlier articles. This article will focus on the inductance of the capacitor footprint and via inductance from the capacitor footprint back to the PCB power planes.

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.

Setting Up Concord Pro Revisions and Lifecycle

Before anything else, some advice. The revisions and lifecycle are an area that takes some planning. It used to be that Concord Pro was primarily for components, but now it has gone far beyond that. With the ability to store and manage many other items, including your various templates, projects, even PDF documents, not everything will have the same revision scheme. Concord Pro is so powerful that it can handle any revision scheme you’d want to set up.

How to Successfully Design a BGA

Whether the board will be placed in a high pressure vessel or underwater, your design will need to withstand pressure to avoid failure. On the enclosure side, your vessel should be rated up to a certain pressure and may require frequent cycling to prevent implosion. On the electronics side, component selection and layout (especially at high voltage) become critical to preventing failure and ensuring reliability.

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.

PCB Design for Testability to Ensure High Yield and Quality

If you remember your days in school, then you probably remember the feeling of happiness and celebration when you pass a big exam. You’ll feel the same sense of adulation when your board spin passes a barrage of pre and post assembly tests, but a complex design might not reach that stage unless you implement the right design for testability methods. There are some simple steps that can help your manufacturer identify and quickly implement important bare-board and in-circuit testing (ICT), especially on critical circuit blocks.

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.
