What is mode conversion
Blog
A Guide to Mode Conversion, Its Causes, and Solutions

On interconnects, such as board-to-board connections or cascaded transmission line arrangements, you have an important EMC compliance metric that is sometimes overlooked. This is mode conversion, which can be visualized in an S-parameter measurement for differential and common-mode signal transmission. In this article, we’ll look at a short overview of mode conversion in high-speed design with some examples from common differential standards.

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.

Transmission lines (coplanar)

The boards use transmission lines to carry high-frequency signals. In addition to microstrip lines, coplanar transmission lines with a ground reference polygon are often found on boards. Coplanar transmission lines propagate the same wave type as microstrip transmission lines, but the electromagnetic field is more concentrated near the conductor, so coplanar lines have lower losses at high frequencies, less dispersion, and less interference to adjacent circuits.

Selecting Materials for High Voltage PCB Design and Layout

High voltage PCBs are subject to certain safety and reliability concerns that you won’t find in most other boards. If your fabrication house specializes in high voltage PCBs and keeps materials in stock, they can likely recommend a material set, as well as a standard stackup you might use for certain voltage ranges and frequencies. 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?

High-Speed Signal Routing: The 5 Important Constraints

After you capture your schematic as an initial layout and create an initial component arrangement, it’s time to define your routing constraints. Doing this early will allow your DRC engine to spot rules violations before you finish your layout. Likewise, you’ll be able to modify the default rule set to meet your layout requirements. Here are the important routing constraints you’ll need to check before you start routing your board.

How to Maximize Copper in Your PCB Design: The Pros and Cons of Copper Pouring Versus Placing

There is a saying in copper pour PCB design, “Copper is free.” It means a PCB editor designer must think in reverse. A board starts off as solid copper, and the copper you don’t want is removed. It is faster to build, less consumptive, and less expensive to make a board that is mostly copper as compared to the same size board that is mostly bare. Picking the correct technique will make the difference between an effortless or frustrating experience.
