Reliability testing and failure analysis of a PCB/PCBA go hand-in-hand; when designs are stressed to the limit, their failure modes need to be determined through thorough inspection and analysis. To get started on this topic, it’s important to understand the qualification aspects that will govern your bare board design and the PCBA. We’ll look at the various dimensions of PCB/PCBA reliability, as well as some of the standard failure analysis techniques used to identify potential design change requirements.
By now, designers should be aware of some important behavior involved in power delivery to components in a PCB, particularly for digital components. All digital components produce and manipulate wideband signals, where the frequency content theoretically extends up to infinite frequency. As such, some radiation may propagate through your PCB, leading to resonant behavior that is not observed on the power rail.
Once your board passes through the standard PCB fabrication process, the bare copper in your PCB will be ready for the application of a surface finish. PCB plating is applied to protect any copper in your PCB that would be exposed through the solder mask, whether it’s a pad, via, or other conductive element. In this article, I’ll run over the different PCB plating material options and their advantages in your PCB.
The PCB supply chain encompasses multiple components, raw materials, and the PCB itself. PCBs and PCB assemblies are often the most technically complex components that are purchased for electronic assemblies and products. The complexity of modern PCBs leads to several challenges for a supply chain management team that may be significantly different when compared with other commodities the team manages. In this brief guide, we'll look in-depth at the PCB supply chain, and specifically what falls within the purview of a procurement and supply chain management team.
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.
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.
Are you looking for a free tool that you can use to calculate the impedance of differential microstrips? We created a simple tool you can use to calculate differential microstrip impedance for a given geometry and dielectric constant. If you’ve been looking for an accurate differential microstrip impedance calculator, then the calculator below is certainly one of the best free tools you’ll find on the internet before you start using field solvers to determine differential pair impedance.
In this article, we’ll discuss the key design features to implement, and steps to take prior to fabrication that will help prevent some common DFM problems. I’ll also provide examples of where I commonly see these PCB DFM problems in signal integrity circuits.
If you’re working with a high-speed digital component, there are some simple power integrity rules that should be followed. However, there is one quantity that is sometimes ignored when building a PDN impedance simulation: the spreading inductance of your plane pair. Here are some points designers should know about the spreading inductance of a plane pair.
In this article, I’ll present some design basics that every new designer should follow to help ensure their design process is successful. Some of these points may challenge the conventional view of how circuit boards are constructed, but they are intended to help balance low noise signaling, manufacturability, and ease of solving a 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.
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?
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.
There are all sorts of version control systems out there that people have been using with their PCB design software. As discussed in Why Use a Version Control System, we looked at different options ranging for local hard drive storage to sophisticated online revisioning systems. In this article we will be reviewing the differences between a standard VCS and Altium 365.
Version Control Systems (VCS) have been around for many decades within the software world but can be surprisingly new to some folks in the electronics design industry. This article will cover what a VCS is, what it does, and why you should be using one for your PCB design projects.
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.
Do you ever have to edit a large group of objects on your design?

Version control has been a staple of software development for decades, but hardware development can benefit just as much from a version control system (VCS). Traditionally, VCS has been managed locally tying you down to a workplace, but advances in cloud technology have removed that limitation. Learn how Altium 365 cloud technology enables working concurrently on designs with built-in version control and evaluate its advantages.

Printed Electronics is emerging to become as common as 3D printing. With this fast-emerging technology, new possibilities have come into the manufacturing arena, allowing engineers and designers to develop products in markets never before realized. With the emergence of many contract manufacturers possessing this capability, the cost is competitive. Quick-turn prototypes and volume production are now all possibilities, and with Altium 365® you stay connected directly with your manufacturer throughout the design process.
An OutJob is simply a pre-configured set of outputs. Each output is configured with its own settings and its own output format, for example, output to a file or to a printer. OutJobs are very flexible – they can include as many or as few outputs as required and any number of OutJobs can be included in a project. The best approach is to use one OutJob to configure all outputs required for each specific type of output being generated from the project.
Getting your PCB layout design done takes patience and precision. Complex footprint geometries, board shape, and dense component placement require accurate primitive positioning. Each stage of PCB design needs a different snapping configuration. Often your settings can be excellent for one stage and be unfavorable for another. Learn more about different snapping usage patterns and best practices of efficient snappings.
