There are plenty of PCB manufacturing services you can find online, and they can all start to blend together. If you’re searching for a new service provider, it can be hard to compare all of them and find the best manufacturer that meets your needs. While experienced designers can spot bogus manufacturers from afar, there is always a temptation to go with the lowest priced, supposedly fastest overseas company you can find. However, there is a lot more that should go into choosing a PCB manufacturing service than just price.

Pi Filters are a type of passive filter that gets its name from the arrangement of the three constituent components in the shape of the Greek letter Pi (π). Pi filters can be designed as either low pass or high pass filters, depending on the components used. The low-pass filter used for power supply filtering is formed from an inductor in series between the input and output with two capacitors, one across the input and the other across the output. Keep reading to learn more about their application in the PCB Design.

The first question that should come up when selecting materials and planning a stackup is: what materials are needed and how many layers should be used? Assuming you’ve determined you need a low-loss laminate and you’ve determined your required layer count, it’s time to consider whether you should use a hybrid stackup. There are a few broad situations where you could consider using a hybrid stackup with low-loss laminates in your PCB

Batteries offer a great power source for electrical devices that need to be mobile or located somewhere where connection to a mains electricity supply or other power source is impossible. The biggest problem with battery power is the expectation of users that the device will operate for significant periods with the need for recharging or replacing the batteries. This demand is placing the onus on the designer to improve efficiency and reduce power demand to meet this need.

A number of us on this blog and in other publications often bring up the concept of target impedance when discussing power integrity in high-speed designs. Some designs will be simple enough that you can take a “set it and forget it” approach to design a functional prototype. For more advanced designs, or if you’re fine-tuning a new board that has existing power integrity problems, target impedance is a real consideration that should be considered in your design.

Dual power supplies are circuits that generate two different output voltages from a single input source. The simplest method of generating dual output voltages is to use a transformer with two taps on the output winding. Bespoke transformers can have any voltage ratio depending on the number of windings in each part of the output side of the transformer.

With digital boards that are nominally running at DC, splitting up a power plane or using multiple power planes is a necessity for routing large currents at standard core/logic levels to digital components. Once you start mixing analog and digital sections into your power layers with multiple nets, it can be difficult to implement clean power in a design if you’re not careful with your layout.

Working between the Electronic and Mechanical design domains brings unique challenges. ECAD and MCAD tools have different design objectives and have evolved down different paths, and so have the way they store and manage their design and project data. To successfully design these products, the designers must fluidly pass design changes back and forth between the ECAD and MCAD domains beyond outdated file exchanges.

High-speed digital PCBs are challenging enough to design, but what about mixed-signal boards? Many modern systems contain elements that operate with both digital and analog signaling, and these systems must be designed to ensure signal integrity in both domains. Altium Designer has the layout and signal integrity tools you need to ensure your mixed-signal PCB design does not experience interference and obeys important design standards.

Just as WiFi 6 and 6E are starting to hit the market and new chipsets become available, WiFi 7 is in the works under the 802.11be standard. While this technology still has not hit the market, I would expect more inquiries for experimental systems, evaluation modules, and surface-mountable modules to come up once the first chipsets become available. Now is the time to start thinking about these systems, especially if you’re developing evaluation products to support WiFi 7.

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. The company struggled with six different software platforms before switching to Altium Designer.

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.
