Level Up Your Design Skills - Altium Designer Getting Started User Guide
We are happy to announce the release of the new Altium Designer Getting Started User Guide. Whether you are new to Altium Designer or you want to brush up on some topics, the Altium Designer Getting Started User Guide will take you from a beginner to a master in PCB design. This is only the beginning! This guide will be updated with new information based on user feedback. Let’s first go over the contents of the guide.
Resources for the Lifelong Learner
A few years ago, in a recap video of AltiumLive, Dr. Eric Bogatin, the Dean of Signal Integrity Academy, stated the following: “Everybody recognizes that you have to continually grow. It’s kind of like in Alice in Wonderland. Alice is in the Red Forest, and the line goes something like this: ‘in this forest, you have to run faster and faster, just to stay in the same place!’ And I think that encapsulates where the industry is today. The most
Antipad Diameter, Crosstalk, and IBM’s Results from IPC APEX EXPO 2021
Interlayer crosstalk begins with antipad diameters, and IBM’s results help us see how antipad diameter on back-drilled PTHs affect signal integrity.
Quantum Computing Electronics vs. Photonics: New Chips Will Shift the Balance
Read more about the newest advance in photonics for quantum computing. The electronics in quantum computers are being challenged by new photonic chips.
Remotely Powering Devices, Wirelessly
With electronic devices being available in smaller and smaller sizes and the prevalence of wi-fi networks, the rise of remote monitoring devices around the home and the workplace continues to grow. Smart heating solutions now place sensors in every room, monitoring everything from temperature to occupancy to provide a highly efficient zonal heating system. Intruder detection systems no longer require thousands of meters of wiring to be installed
Guidelines for Creating Useful Schematic Symbols
The schematic symbols that you use to represent the components are at the heart of your schematic design. The quality of the symbol and how it is arranged can be one of the most critical factors influencing your schematic’s readability. A poor quality schematic symbol will lead to an unreadable schematic sheet that is difficult to understand. I created the largest open-source library for Altium Designer over five years ago, initially as a way to
Using a Thermal Camera for PCB Diagnostics
There has likely been a time when you’ve powered on a freshly built prototype for the first time, only to find you’ve hit the current limit on the lab power supply. Even as you increase the current limit to way beyond what you would expect your board to draw, the lab power supply is still limited. If it’s safe, you poke around the board with your finger, but you can’t feel any parts that are hot to the touch. Also, probing around with a
What does AMD’s purchase of Xilinx mean for the electronics world?
Who is Xilinx? While AMD is focused on microprocessor production, Xilinx is a specialist producer of FPGA (field-programmable gate arrays), which are particularly useful for telecommunications applications, and the development of 5G across the world has opened up significant growth in this sector. The expected number of new 5G cellular base stations required over the next five to ten years will be in the millions. Xilinx has been one of the front
IPC-2551 Digital Twin Standard Released
Read our brief on the new IPC-2551 standard and how digital twins might be used in the PCB industry.
Create a Buck-Boost Power Supply
In this series of articles, we’re looking at the design and implementation of the main types of power regulators and converters you might use in an electronics project. I gave a graduate engineer who I mentor a series of requirements to demonstrate each of these types and have recorded the results here so you can work through the same exercises and hopefully come up with the same results. The next switching regulator is the last in our switching

Assembly: The Last Step In The PCB Product Development Process
As pointed out in previous articles, design is the first step in the PCB product development process, so the board designer needs to understand how the downstream processes will impact his design processes/selections/decisions, and this understanding needs to encompass both technical and financial considerations. These deliberations are viewed and weighted as trade-offs. What might make sense from a technical standpoint may not always make sense
Addressing Differential Signaling In Flex Circuits
As noted in many previous articles, due to high-speed and high data-rate designs, most modern products utilize differential signaling. If utilizing the right design protocols and design toolsets, handling differential signaling in standard, rigid PCBs is easily doable. But utilizing differential signaling in flex circuits creates another set of issues, questions, and design challenges. This article will address how differential signaling is

Neuromorphic Computing Chips Make Transistors Feel Obsolete
Intel’s upcoming platform for neuromorphic computing, the Loihi neuromorphic processor, reflects a broader trend in the AI hardware community, but you wouldn’t know it from looking at the packaging. The Loihi processor packs major changes to the underlying transistor architecture and uses a unique signaling method used for computation. Intel’s products and other chips from hardware startups are starting to resemble the functionality in the human
