PCB Mountable Connectors: SMD vs. Through-hole

Selecting a connector is as much an art as it is a science. The artistic side is all about aesthetics and satisfying clearances, while the scientific side is all about signal integrity. For PCB mountable connectors, you’ll need to choose between surface-mounted or through-hole connectors, and you’ll need to consider how each type affects signal integrity in your application. Here’s what you need to think about beyond the standard connector specifications.

PCB Via Current-Carrying Capacity: How Hot is Too Hot?

Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool.

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.

How to Assign Names to Polygons

For some polygons, it is not always reasonable to use an automatically generated name so a custom name is needed. With a proper polygon name, you can quickly find the desired polygon in a list and correctly set the pour priority in relation to other polygons. By using unique names, you can create design rules that apply only to specified polygons.

What is mode conversion

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.

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. Yes, capacitors exist, but all capacitors are non-ideal, and it is this deviation from a theoretical capacitance that determines how to impedance match a load that exhibits capacitive behavior. 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. PCBs designed using high-density interconnect techniques tend to be smaller as more components are packed in a smaller space.
