An effective product lifecycle management (PLM) solution will integrate the tools and processes employed to design, develop and manufacture a new device. This solution goes beyond engineering activities to include the project management, process control, and financial management of the end-to-end business processes. PLM solutions create this collaborative environment where product development can flourish, bringing additional benefits in efficiencies and transparent communications, breaking silos, and speeding up the development process.

With ever increasing speeds in high-speed data systems comes a couple of PCB layout challenges. High-speed busses like DDR, VME, PCIe just to mention a few can all reach data transfer speeds that require strict timing with very tight tolerances, thereby leaving very little slack in the PCB layout. Watch this on-demand webinar to learn why it's imperative to match track lengths in high-speed data systems and differential signals. You’ll see how to properly define PCB length matching and time delay constraints, and how to effectively route high-speed signals in Altium Designer®.

In this article, we want to get closer to a realistic description of tight coupling vs. loose coupling in terms of differential pair spacing, as well as how the differential pair spacing affects things like impedance, differential-mode noise, reception of common-mode noise, and termination. As we’ll see, the focus on tight coupling has its merits, but it’s often cited as necessary for the wrong reasons.

You’ve possibly gone through plenty of engineering design reviews, both on the front-end of a project and the back-end before manufacturing. Engineering design reviews are performed to accomplish multiple objectives, and with many engineering teams taking a systems-based approach to design and production, electronics design teams will need to review much more than just a PCB layout and BOM. Today’s challenges with sourcing, manufacturability, reliability, and mechanical constraints are all areas that must be confronted in real designs

One of the most common points of failure of a device occurs even before you start to layout your circuit board. Mistakes in your schematic design can easily make their way all the way into prototypes or production without a second thought once layout starts. In this article, I’m not going to extol the virtues of a good schematic design. Instead, this article is a simple no frills checklist.

One common question from designers is current-carrying capacity of conductors in a PCB. 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. Let’s dig into the current state of thermal demands on vias in PCBs and how they compare to internal and external PCB traces.

SPICE simulation saves you critical time in the prototyping phase. Understanding your simulation interface makes it simple to analyze how your circuits work in different scenarios. Altium Designer provides an intuitive, dedicated interface to support your simulation verification, setup, and analysis directly in your schematic environment. You also benefit from growing support for popular model formats, as well as generic models, simplifying circuit definition and simulation.

A combination of good printed circuit board design and good shielding mitigates EMI. Good PCB design for EMI shielding revolves around the layout, the placement of filters, and ground planes. A well-designed PCB minimizes parasitic capacitance and ground loops. Keep reading to learn more about PCB shielding.

Any project can get very complex, and the PCB design team needs to track revisions throughout a project. Why worry about tracking revisions? In the event you ever receive changes to product functional requirements, major changes are made to your product’s architecture, or you’re ready to finalize the design and prepare for fabrication, it’s best to clone a project at its current state and begin working on a new version. Keeping track of all these design changes in a PCB design project takes the type of hardware version control tools you’ll find in Altium 365™.

Printed circuit board fabricators have become skilled at manufacturing these technologies and also at understanding the reliability and producibility challenges associated with high-density-interconnect technology. Let’s look at where the PCB industry is at today.

What can the industry do to support PCB designers as they continue taking a more active role in product development? Here at Altium, there has been a progressive shift towards looking at the system level and creating tools that get designers more involved throughout the product development process. As the saying goes, over the wall engineering is over… today’s most successful products are built in a collaborative process.

As the 5G rollout progresses and researchers continue to discuss 6G, many new 5G-capable products operating in sub-GHz and mmWave bands are reaching the marketplace. Devices that will include a 5G-compatible front-end, whether small stations/repeaters or handheld devices, use phased arrays as high-gain antenna systems to provide high data throughput without losing range at higher frequencies.

Via protection is an important part of modern PCB design. It provides additional benefits in PCB manufacturing and assembly, increasing the number of acceptable products.

Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system.

A design project doesn’t appear out of nowhere. The design process spreads over time, and project documents change. Schematic documents gradually become more complex, new functional blocks appear, and already finished parts can be modified and updated.

Capacitance is your friend whenever you need stable power integrity, which is why there is so much focus on decoupling capacitors. While these components are important and they can be used to provide targeted power integrity solutions to certain components, there is one specialty material used to supercharge capacitance in your PCB stackup or package substrate.

The problems you can experience with components and libraries are endless. These problems are the most significant source of design issues and the biggest reason behind respins, costing companies untold amounts of lost profit annually.
If you want to have a better understanding of how to use Altium 365 to maintain a strong and centralized library that is free of problems and headaches, you may want to consider attending this lecture.

As much as we would like to build every high speed PCB perfectly, with ideal SI/PI/EMI characteristics, it isn’t always possible due to many practical constraints. Sometimes a stackup can be “good enough,” even for a high-speed PCB. This always comes from the need to balance engineering constraints, functional requirements, and the need to ensure signal and power integrity in a high-speed design, and finally to ensure compliance with EMC requirements.

Involving the whole team that will bring a product to completion early on in the development cycle is vital to efficient development. Design reviews with all the relevant parties are critical at each step of the design process, starting with high-level component selection, then through the schematic capture and PCB layout stages.

Ergonomics and convenience are important issues when designing a printed circuit board and the device as a whole. A lot of Altium Designer tools are aimed at solving them. These include Countersink and Counterbore holes, which allow the use of various types of screws in the mounting holes of the board.

The development of electronic devices always involves the release of many different types of files. And these files are not static - they change as the project progresses. When filling a project with data, a user creates new files, modifies outdated files that have become irrelevant. Managing project data is a separate task, especially for large developments where several participants with different specializations are involved in the process.

High-speed PCBs often require tuning groups of tracks, both single and differential. Altium Designer includes powerful tools that allow you to solve such tasks quickly and with high quality. Study this document and achieve the desired result even faster.

There is one confusion related to impedance matching that comes up again and again, and it appears to be a fundamental confusion between reflection and power delivery. This leads to an apparent contradiction that arises when we try to generalize power delivery to wave reflection, despite the fact that the two were not meant to be related.

Routing is one of the most time-consuming stages of PCB design. Altium Designer has a large set of tools that allow you to do it as accurately and quickly as possible. This document will help you to learn how to manage your routing effectively and use it to its fullest extent.

RF systems operate with specific impedance values across entire interconnects, including on PCBs. Not all RF components are packaged in integrated circuits with defined impedances, so impedance matching circuits and line sections are needed to ensure signal transmission between different sections of an interconnect. One of these impedance matching techniques is the quarter-wave impedance transformer, which can be implemented as a printed trace with specific impedance.
