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.

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?
