Once you’ve run out of room on your 4-layer PCB, it’s time to graduate to a 6-layer board. The additional layer can give you room for more signals, an additional plane pair, or a mix of conductors. How you use these extra layers is less important than how you arrange them in the PCB stackup, as well as how you route on a 6-layer PCB. If you’ve never used a 6-layer board before, or you’ve had EMI troubles with this stackup that are difficult to solve, keep reading to see some 6-layer PCB design guidelines and best practices.
There are many aspects to designing a PCB. One of the larger aspects has to do with managing your components. We all need components for our designs, but are those components in our library and designs up-to-date or even purchasable? These questions need to be answered before we can safely use them. If not, we could just be wasting our time designing with invalid components. Altium Designer® has several tools to help you manage the components in your libraries and designs.
We are happy to announce that the Altium Designer 22.5 update is now available. Altium Designer 22.5 continues to focus on improving the user experience, as well as performance and stability of the software, based on feedback from our users. Check out the key new features in the What's New section on the left side of this window!
PCB stackups often incorporate slightly dissimilar materials that could pose a reliability problem. Hybrid PCBs are one case where the PCB stackup will include different materials, typically a standard FR4 laminate and a PTFE laminate for RF PCBs. Designers who want to take the lead on material selection when designing their hybrid stackups should consider these factors that affect reliability. As with any PCB stackup, make sure you get your fabricator involved in the manufacturing process early to ensure reliability problems do not arise during production.
In a previous article about circuit simulation and reliability, I looked at how Monte Carlo analysis is commonly used to evaluate circuits that are subject to random variations in component values. Sensitivity analysis is a bit different and it tells you how the operating characteristics of your circuit change in a specific direction. Compared to a Monte Carlo simulation, sensitivity analysis gives you a convenient way to predict exactly how the operating characteristics will change if you were to deliberately increase or decrease the value of a component.
Field Programmable Gate Arrays, or FPGAs, have become ubiquitous amongst high-speed, real-time digital systems. The speed at which FPGAs operate continues to increase at a dizzying pace but their adoption into Continuous Integration pipelines seems not to trail as closely. In this article we will review the concept of CI pipelines, their application to FPGAs, and look at examples on how to set this up.
Conflicts can occur when multiple people work on the same project simultaneously. The user might not realize that they are not looking at the latest version of the documentation, leading to problems later. To address this issue, Altium features an intuitive graphical user interface that allows you to examine conflicts quickly and carefully
Component creation is a necessary evil when it comes to design, and it’s something we all need to do. But instead of spending hours creating your components and having them turn into a complete roadblock, let it be just a simple bump on the road. Altium Designer has several tools available to you in order to create the different aspects of a component, including the symbol, footprint, 3D model parametric data, supply chain information, and more
Anytime you place a component in your PCB, it’s almost like you’re gambling. All components have tolerances, and some of these are very precise, but others components can have very wide tolerances on their nominal values. In the event the tolerances on these components become too large, how can you predict how these tolerances will affect your circuits?
If you look in datasheets for most components, you’ll often find a recommended land pattern, usually alongside some mechanical package information and assembly information. This is not always the case with BGA components, especially components with high ball count. There are a few reasons for this that we can speculate: those ball counts might just be too big to put into a single page, or the manufacturer just expects you to know how to create that land pattern.
Molded interconnect devices are essentially plastic molded substrates with traces running along any surface, including at right angles and running vertically. Altium users can use the new 3D Routing extension to design their own component carriers, which can be mounted vertically in a standard assembly process. If you’ve always wanted to vertically mount components or entire circuits, but without the expense of adding a flex section to your design, the new 3D Routing extension with HARTING’s component carrier designs provides a unique solution.

Electronic parts may now cycle from launch to end-of-life in just a few years, but many systems are expected to serve for 10–20+ years. Here’s how to build a component selection process that aligns engineering, procurement and design for longevity and stability.
As component lead-times extend and obsolescence becomes a persistent threat, PCB projects demand more than schematic capture and layout tools alone. This article details how ECAD software with embedded supply-chain intelligence can: unify engineering and procurement teams; provide visibility into stock levels, lead times and alternates; and enable proactive risk mitigation within the design loop.
