Hello, Welcome to the Altium Learning Hub

Introduction Printed circuit board (PCB) designers are needed now more than ever, and this need is only going to increase in the future, as more and more veteran PCB design engineers retire, while the challenges and complexities of PCB design increase. No longer is PCB design simply about ‘connecting the dots’ but rather an intricate science, that if neglected, will leave you with a non-functioning product. Unfortunately, PCB design is not...

Click here to jump to the viewer embed and browse this project There is a group of products I work on that require boot and configuration over RS-232 or UART, and I like to boot prototypes by connecting them to my laptop. However, in order to access that interface, I have to send data and receive over a COM port. Unfortunately, my laptop only has USB ports, so I need to convert between the USB port and the UART interface. Normally I use a small...

Flexible circuits have been around for decades and are one of the fastest growing segments of the printed circuit board market.  I imagine at this point in time, most experienced printed circuit board designers are aware of the benefits of using flexible circuit technology: Solves a packaging issue Reducing space and weight needed Reduced assembly costs Facilitates dynamic flexing Thermal management  Improves product aesthetics Biocompatibility...

As pedestrian as it may seem, power delivery on the PCB and in advanced packages remains one of the biggest challenges facing designers, particularly in environments like data center, edge computing, mobile devices, and telecom/networking. Massive amounts of data are being moved through extremely high data rate channels in these environments, and as much as we focus on signal integrity, none of these systems will work without stable power. Power...

The first time you fire up on a new circuit board project can be both exciting and nerve-wracking at the same time. On the one hand, it's an opportunity to bring your creation to life. But, on the other hand, mistakes in this phase can damage the board or its components and ruin weeks or even months of work. {"preview_thumbnail":"/sites/default/files/styles/video_embed_wysiwyg_preview/public/video_thumbnails/M1B4t4Ukrwk.jpg?itok=3yuUNYiN","video...

The printed circuit board industry is all abuzz about the CHIPS Act, as it should be.  There are also many advocating for the CHIPS Act to include package substrate technology and ultra-high density interconnect technology.  I couldn’t agree more!  We need to look at the full supply chain for this endeavor to be successful.  There has been a lot of activity around the ultra-HDI technology: fabricators are now easily providing trace width and...

Let’s set the scene: you finished your PCB layout and sent the board off for fabrication. After successful fabrication, the board is sent off to an assembly facility, and the assembler is preparing your PCB for wave/reflow soldering. While preparing the board, they discover that one of your footprints is incorrect, and a component can’t be mounted to the PCB! Sometimes, footprints end up being incorrect, and they simply aren’t caught in a design...
