Hello, Welcome to the Altium Learning Hub

There is one high-speed PCB design rule that has been over-communicated and misunderstood ever since its inception: the transmission line critical length rule. This rule is also known as the 25% rise time rule. The rule basically states conditions under which you don’t need to calculate trace impedance by stating: if the length of a trace is less than 25% of the distance traveled by a digital signal, then the trace impedance does not matter. ...

IPC continues to develop resources to bring awareness about the electronics industry to the young generation. In this episode, we are very fortunate to have Charlene Gunther, the Senior Director of the IPC Education Foundation. We will talk about IPC’s efforts to involve students in engaging activities that will introduce the electronic industry to them as early as high school. Join us and watch through the end. We added some great resources...

Enclosures are a vital part of an electronic project, though until recently, designing a bespoke case was an expensive and time-consuming process. However, advances in integrating Electrical Computer-Aided Design (ECAD) and Mechanical Computer-Aided Design (MCAD) packages make this simple. We'll demonstrate how easy it is in this article, where we will integrate SolidWorks MCAD with Altium Designer, thanks to the power of Altium's MCAD CoDesigner...

In the last article, How do I Get Started with my Altium 365 Component Library?, we walked through the basics of component creation with the Manufacturer Part Search (MPS) panel in the Altium 365 Workspace. Connections to Octopart and IHS Markit populate the component information of the MPS panel. However, manufacturers and suppliers generally provide the component models directly through their connections to the Octopart database creating...

Solidworks PCB to Altium Designer In this migration guide we are going to focus on importing SOLIDWORKS PCB designs to Altium Designer. If you need to migrate from another tool, please refer to their specific migration guide below or explore our Documentation page for tips on importing your designs. Migrating from Autodesk EAGLE to Altium Designer Migrating from OrCAD to Altium Designer Migrating from Siemens PADS to Altium Designer Migrating...

What is Ultra-HDI? There is a lot of conversation about “Ultra-HDI” especially with all of the anticipated work being done as part of the CHIPS Act.  In my experience, Ultra-HDI means different things to different people depending on where their capabilities and expertise are.  IPC has created a working group to address ultra-HDI and their position is that to be considered ultra-HDI, a design needs to include one or more of the following...

RF bias tees are used to separate DC and AC power along an interconnect. It is a 2-input, 1-output device that uses reactive elements to provide a power flow along different directions. In a previous project with an RF power amplifier layout, there is a bias tee in the design that is used to provide DC power to the amplifier while also allowing RF power to propagate towards the output SMA connector. In this article, I’ll outline how to design...

In this episode, we will learn so much about embedded CAN bus, for automobile security and performance straight from the water host, Ken Tindell the CTO of Canis Labs. A lot of interesting facts about cyber security and automobile hacking that you would not want to miss! Watch through the end and make sure to check the additional resources below.

Click here to jump to the viewer embed and browse this project RF power amplifiers can be found in any wireless product, often built into chipsets or modems. However, in some specialty systems, you might need higher power output at a specific frequency, and this requires a discrete amplifier circuit to provide that power. These systems can take an external oscillator and amplify it to provide a high power signal, or a local oscillator can be...
