Altium 20.1’s new Component Sync feature allows you to synchronize virtually any database or database Library with Altium 365, taking advantage of both approaches strengths.
If you’ve created your next great schematic, there is a lot going on behind the scenes in your design software. A schematic netlist is one of the central pieces of information that will be used in multiple features in your design software to create a real PCB. Your schematic netlist provides both electrical connectivity information, and reflects the functional structure of your design data in a single set of data.
An SMPS is one of those quiet (yet electrically noisy) devices that makes your favorite electronics run smoothly. Among the numerous DC-DC converter topologies, a buck converter finds plenty of uses for stepping down the input voltage to a lower level while providing high efficiency power conversion. A common question around component selection for these power converters is how to select an inductor for a buck converter. The goal in working with an inductor and other components in a buck converter is to limit power loss to heat and while minimizing current ripple.
GPS-capable devices range from your phone to your smartwatch; simply type in your destination and follow the directions. Simple, right? According to the Washington Post, we should all stop using GPS as it’s ruining the navigation centers of our brains. Despite the neurological effects on perception and judgment, the U.S. Department of Transportation (DOT) aims to find alternatives to GPS to provide redundancy.
The list of features available in Bluetooth just got a little longer since the release of Bluetooth 5.1. If you want to incorporate a Bluetooth 5.1 SoC into your new product, you have two primary options for bringing this component into your board. The first is as an SoC that mounts to your board just like any other component. The other option is to bring a module into your new board—directly onto the surface layer. Here’s what you need to know about a Bluetooth 5.1 SoC or module in your next IoT product.

Since its introduction in the late 90s, the USB standard has never ceased to grow in popularity. There has been a growing trend toward USB being a power delivery interface with data, rather than a data interface that can supply power, as the 1.0 specification originally intended. To supply the increasing thirst for power over USB, the USB 3.0 Spec with Type-C began implementing the Power Delivery standard, which you should consider using for your next electronics project.
There are many types of circuit board tests available in electronics manufacturing today, each having unique goals and characteristics. This article presents guidelines at the design level (schematic and layout) to enable the use of in-circuit testing (ICT) fixtures to verify proper component assembly. These simple test fixtures allow your board to be tested as its assembled, which helps identify and remove failed boards from your production run.
Technological advancements have been a hallmark of the past few decades, from the widespread adoption of internet technology to the smartphones and wireless devices we rely on every day to stay connected. Orlan Thatcher, Board Layout Specialist at Cirris Systems, could never have predicted the demand their services would generate.

I used to work in a research lab that worked primarily with RFID (Radio Frequency IDentification) and NFC (Near Field Communication) technology, particularly for the agriculture industry and cattle identification. These were very specialized fields; however, the lab also worked on projects which involved retail and various other applications for NFC. It’s an amazing technology that you might be using every day without thinking about it - building access to your mobile phone payments, for instance.
You need to define your PCB geometry in the context of your enclosure. If your board cannot physically be assembled into the final product, it doesn't matter how well laid out it is electrically. This webinar focuses on how the MCAD CoDesigner allows you to edit your PCB in the context of a higher-level assembly, allowing you to respect the relevant mechanical constraints.
In Part 1 of this article, I described the first steps that occur during the PCB fabrication process. They detailed the inner layer processing effort as well as the efforts that take place during the transition from inner layer processing to lamination. This part of the article will provide a detailed description of the lamination, drilling and plating processes.
There are still a number of designers - perhaps most of them - who have never toured a PCB fabrication facility. They are also unaware of the various steps that occur during the fabrication process. The purpose of this article is to describe those steps and what transpires in each of them. Part 1 of this article focuses on inner layer processing and the steps that are done prior the lamination process.
Working with local libraries seems like a simple solution, but we often don’t take into account the added time spent maintaining libraries and sharing them between team members. This webinar showcases the advantages of component storage in Аltium 365 to resolve the issues of local libraries and component management.
Every piece of electronic equipment starts with a great idea. Transforming great ideas into real, physical products takes a team of talented individuals and multiple companies coming together to make everything from the internal components to the external hardware. Paul Payen de la Garanderie, Founder and Owner of AW Audio, an engineering services company based in France, understands these challenges very well. With an extensive background in the Audio/Visual industry, Paul has had to work with multiple companies over the years, from small start-ups to celebrated AV firms.
At this time, at least a quarter of the world’s population is under quarantine, with workers unable to go to offices or factories, leading to fundamental disabling of the world economy. The electronics industry is suffering greatly as well, dealing with a supply shock from factories shutting down in Southeast Asia, to demand-side shocks from Western markets literally shutting down. Now it is the electrical engineers taking the lead with additive PCB manufacturing.

There are all sorts of version control systems (VCS) 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.
Controlled impedance routing at high frequencies is difficult enough, and it's important to make sure that you stay within your loss budget on long routes or in lossy media. When you have to route a long trace or a long differential pair to a connector or another component, what can you do if you're reaching the end of your loss budget? In this article, we’ll take a look at the skip reference routing method and explain how it can help recover some loss budget in a lossy interconnect.
We are pleased to announce that Altium 365 is officially SOC 2 Type 1 certified. System and Organization Controls (SOC) 2 is a widely recognized attestation of security compliance defined by the AICPA and is considered the standard for ensuring data security and operational maturity. A SOC 2 certification provides valuable information for companies to assess the quality of the security provided by a service such as Altium 365.
It’s no secret that component shortages have become more frequent this year. Companies will continue to grapple with supply chain challenges into 2022 and beyond. The impact of manufacturing delays can be substantial if a part is not available. Delays occur and sales plans get put on hold. It can also be very expensive and risky to replace parts from multiple sources. Fortunately, many shortages can be avoided by introducing proactive supply chain practices.
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?
