Hello, Welcome to the Altium Learning Hub

Series and parallel termination are the most common resistive termination options for digital signaling. The reason is that resistance is a wideband quantity and does not start to be affected by parasitics until well into the GHz range. At the channel bandwidth associated with most digital signals, there are cases where an unterminated line actually needs termination, even if there is no impedance specification in the interface. As both options...

Altium and Ansys are redefining the way ECAD and Simulation engineers work together. Today, we are joined by Joao Beck, Altium's Director of Enterprise Technical Marketing, to give us all the details. The Altium-Ansys Digital Bridge is a seamless, digital connection between ECAD and Simulation. This is just another step in Altium's quest toward a digital ecosystem. Make sure to watch the entire episode so you can fully understand what's coming...

If you follow what I do in signal integrity publications and in seminars, then you have probably seen several articles on calculating lossy transmission line impedance using analytical formulas and calculators. Using a calculator and some numerical techniques is much simpler than setting up a 3D electromagnetic field solver. The calculators you’ll find online will omit very important information, so it is worth investigating whether you can use...

Even if you aren’t using top-of-the-line design software, you’ll still notice something very important in your PCB footprint layers: solder mask and paste mask openings. These will be placed into stencils and used to fabricate and assemble your PCB. With designers sometimes finding themselves needing to create their own components, it’s worth asking, what is the right value for mask expansions to set in your PCB footprint? The next question that...

An Introduction to Baxandall Active Volume Control Inspired by Douglas Self’s book on audio electronics (‘Small Signal Audio Design’) and his power amplifier design consisting of a massively-parallel array of NE5532 op-amps, I set out to design a headphone amplifier that uses similar techniques but scaled down due to the lower power requirements. The resulting amplifier utilizes many NE5532 op-amps (the first version used 44 in total!) and is...

The collaboration between electronic design (ECAD) and mechanical design (MCAD) teams is essential for successful product development. However, integrating these two domains has long been a hurdle for engineers. This blog post will explore the synergy of Altium Designer, Fusion 360 and Altium MCAD CoDesigner, showcasing how this powerful combination bridges the gap between ECAD and MCAD, fostering seamless collaboration and boosting design...

When connecting multiple circuit boards in a space-constrained environment without the budget for a rigid-flex PCB assembly, selecting the appropriate interconnect solution becomes crucial. Options include FPC connectors, flexible flat cables (FFCs), or off-the-shelf connectors integrated into a wire harness. Determining the best choice depends on your specific design requirements. Flex Cables vs. Ribbon Cables Flexible Flat Cables (FFCs) and...

We're joined today by the Technology Ambassador at Ventec and President of the European Institute for the PCB Community (EIPC), Alun Morgan. He and host Zach Peterson have a broad, thoughtful conversation centered on PCB manufacturing. They chat about emerging manufacturing markets, the potential for supplier buyouts, reshoring, automation, and much more. This is a fascinating conversation for anyone looking to get a current view on the...
