Hello, Welcome to the Altium Learning Hub

We are continuing the journey through lid assembly design on our Open Source Laptop project. Designing a test adapter — Layout Now we have to put all of our work in an actual hardware design. The layout of this board is straightforward, as we only have one high-speed interface to pay special attention to. The DisplayPort interface can de-skew up to 20UI per specification. UI is short for Unit Interval which is the reciprocal of the bit rate...

Circuit boards rarely operate in isolation. Working with projects that house multiple board designs is a growing scenario in the electronics industry. You need to manage the whole system’s connections, resolve conflicts, and update system-child projects. You also need to manage board rotation, alignment, and fitting into enclosures. How do you conquer all of these challenges? There exist several methods to establish the logical (schematic)...

It’s a sad fact of PCB design: through-hole components don’t get a lot of love. They tend to be older technology, or they could be mechanical parts that need to have a very stable attachment to the PCB. Through-hole parts are also often found in power electronics when working with AC power coming out of a wall outlet. Still, these components might need to live on a PCB alongside standard SMD parts. If everything on your board is through-hole...

Industrial control systems (ICS) are the backbone of modern industry, playing a crucial role in the operation and management of many processes. Through a combination of software and hardware, these systems monitor and regulate machinery, production lines and other critical activities. As we move further into the Industry 4.0 era, it is increasingly evident how much we rely on advances in electronic components to enhance and modernize these...

The demands for innovation and efficiency continue to push the boundaries of technology. But as technology has evolved and products have demanded more complex features, the single-board designs of yesteryears are often no longer sufficient. Enter multi-board designs, which entail multiple PCBs interconnected to function as one unit. This sophistication, while powerful, demands a robust harness design for seamless and efficient interconnection...

Welcome back to the open-source laptop project! In this update we will move one step closer to the design phase of the project. This is the first hands-on experience with one of the core components of the laptop — the display panel! We will decide which display panel to use, how we can integrate it into the lid, and we are going to design, assemble, and test a small DisplayPort to embedded DisplayPort adapter to light up the screen for the first...

The products you buy off-the-shelf or over the web all live inside an enclosure. For some products, the enclosure is intentionally ruggedized, with the goal of withstanding some harsh environment or a mechanical shock. So what exactly makes an enclosure rugged? I’ve compiled some examples from military computing and industrial systems. When those folks say something is rugged, they really mean rugged! So if you want to get some ideas for...

Today we have a fascinating conversation about PCB manufacturing, reshoring, testing, and much more with Cody Endlich, Head of Strategic Sourcing at MacroFab. He and Tech Consultant Zach Peterson discuss the latest trends in manufacturing, procurement, and supplier dynamics. This is a wonderful convo for anyone interested in the future of PCB sourcing and manufacturing. Listen to the Episode: Download this episode. Watch the Episode: Show...
