Hello, Welcome to the Altium Learning Hub

In my journeys through the land of LinkedIn, I’ve been seeing people post links to their via impedance calculators. Calculator applications are always nice to use for quick estimates of some aspect of a design, with stripline and microstrip dimensions being among the most common. For instance, I keep a skin effect resistance calculator in my toolbar so I can get quick estimates of copper-related losses in high-speed/RF interconnects. The problem...

During our Ensuring First Pass Manufacturing Success webinar, we discussed the basics of using the Altium Designer Project Releaser to package your project before sending it off to your manufacturer. Now, let's take it a step further! In this webinar, you'll see how combining Project Releaser with Altium 365 provides designers with advanced capabilities that help projects get manufactured quickly and reliably. Join this free webinar and demo to...

Any new PCB you want to build will need a power source, and the power you need to provide is often stepped down from a noisier unregulated source. An example is an output from a full-wave rectifier, which will contain some residual ripple at the output port. Another possibility is the noise from an upstream converter. In other cases, you are drawing power from a battery, and the battery’s voltage/current output will change over time or with...

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. There are several types of vias protection detailed in the IPC-4761 Design Guide for Protection of Printed Board Via Structures and on pages 5-11 of this document. Advantages of Via Protection Common situations where vias protection is recommended or required: Support For...

Just as you get used to PCIe 5.0, they decide to release another standard! Ever since PCI Express was introduced as a replacement for the original PCI specification, the PCI-SIG standard group has doubled the bandwidth approximately every 3 years. The cadence of performance changes and bandwidth increases suddenly hastened around the time of PCIe Gen4, with the current time between generational releases of about 2 years. Since its introduction...

I am very enthusiastic about the semi-additive processes now available to PCB fabricators of all sizes and spend a fair amount of time talking about potential designs that could benefit from the ability to route with 15 micron or 25-micron trace and space.  While mSAP has been utilized in select very high-volume manufacturing facilities in Asia, for technology such as smart phones, it is a technology that has largely been unavailable for low to...
