Hello, Welcome to the Altium Learning Hub

In both of our books, Right the First Time, A Practical Handbook on High Speed PCB and System Design, Volumes 1 and 2, as well as in our on-site and public courses, we talk about the value of a series-terminated transmission line. With this type of transmission line, no power is being used unless the line is being charged up. This enables a lot of computing with a minimum of power. But having a clear understanding of how this type of line...

Altium Concord Pro™ as a standalone product and brand name has been discontinued and the capabilities are now available as part of our Altium enterprise solutions. Learn more here. Introduction This may come as a shock to some, but I was raised on a farm back in Pennsylvania. Every spring, we would prepare for the planting season. It was amazing to me to take the seeds, plant them in the field, tend them, and in time end up with a crop. Within...

Judy Warner: Rob, please give us a brief overview of Calumet and your role there. Rob Cooke: I've been with Calumet Electronics for just over a year and a half in the role of Director of Engineering Services.  I have responsibility for our CAM/Tooling group that handles new orders. I also oversee our Design Engineering services group and our Software Development team.  Calumet Electronics is a 50-year-old company that has been making Printed...

This week’s live webinar will showcase 10 hidden secrets in Altium Designer 20 and learn how you can leverage them to elevate your design experience.

The concept of revisioning in electronics design has stayed fairly standard across the industry. A revision will typically consist of a letter and sometimes contain a number. There are many other revision schemes which people have experimented with, but, from my experience, the standard letter revision seems to be prevalent within our industry. One question that I have always asked myself is: What happened to all the revisions in between? I...

I live in a rural village that tends to have intermittent power when there are high winds or storms. Because of this, my computers, servers, and network equipment are all on relatively low-cost, uninterruptible power supplies. These all run on sealed lead acid batteries and are not an overly efficient way to power a DC device such as a Raspberry Pi or internet router as the incoming mains. AC charges a DC battery, which then creates AC power...

If there has been one constant about products designed for the internet/networking market spaces, it’s the data rate and frequency of operation at which the technology operates. In some cases, it can be argued that these two dynamics (data rate and frequency) are not necessarily proportional. Still, the former of these meets the criterion of being TNGT (the next greatest technology). With software, the evolution of products is mostly...

See how easy it is to create a prototype from scratch, automatically generate manufacturing files and standardized documentation in only 36.5 minutes - and all of this by only using the tools included in the unified design environment of Altium Designer 20. WE WILL SHOWCASE THE FOLLOWING: Schematic entry and component selection Generating a bill of material with current supplier information from the field PCB-Design and board outline fitting...

If you’re about my age or older, you probably remember being impressed with your old 14.4 kbps dialup internet. Those days seem long gone at this point as gigabit speeds are now commonplace. You can thank the advances by the signal integrity community and IC designers for getting us to this point. Still, one has to wonder whether current interconnect technologies are being pushed to their limits. Data rates on PCB interconnects have increased...
