Hello, Welcome to the Altium Learning Hub

For some modeling tasks, an impedance vs. frequency curve for a ferrite bead is needed to properly estimate or simulate circuit behavior. This applies to SPICE simulations of power supplies or filtering applications involving ferrites. While we generally don't advocate the use of ferrites in ways that have been popularized in the past, it's very important to test and validate any proposed design involving ferrites. When a SPICE model for a...

Printed circuit board (PCB) design is continuously advancing, requiring electronics designers to deliver new functionality and reliability while always keeping a focus on cost efficiency. By understanding the relationship between choosing components and the effect on PCB costs, designers and engineers can make better decisions when optimizing their designs for performance and cost.  This article explores various classifications of electronic...

The most common add-in card in standard desktop computers and embedded computers is the PCIe card. PCIe add-in cards come in multiple form factors and use an edge slot connector, mounting either vertically or at a right angle along a motherboard. You also have different types of PCIe devices, such as SSDs or modules that plug into an M.2 connector. In this article, I'll cover the mechanical and electrical requirements for PCIe add-in cards that...

With the growing demand for PCBs in just about every electronic device in development, time is of the essence. For manufacturers or even hobbyists, quickly getting hold of a functional prototype can be the difference between success and missed opportunities; as a solution to this time-intensive problem, some manufacturers have started offering quick-turn PCBs.  Note from the editor: The text below lists several companies offering quick-turn PCB...

Historically, PCB designers have faced the ongoing challenge of finding the right component for whichever purpose their eventual manufactured PCB will serve. With supply shortages, poor quality parts, and unreliable vendors filling the space, that has proven troublesome. Today, with the oversaturation of the tech market and growing consumer demand for bigger and better, designers now face an even more difficult task: sourcing cutting-edge...

The medical device industry relies heavily on technology to deliver life-saving treatments and diagnostics. At the heart of many of the devices used, you will find the printed circuit board—a network of electrical pathways etched onto a laminate substrate. Given the industry in which devices are used, it is of the utmost importance that designers guarantee both quality and compliance in their PCB designs to ensure patient safety and device...

From innovative new electronics to the most powerful artificial intelligence (AI) use cases, advanced chips form the backbone of the latest technologies—the current rate of innovation hinges on more power in smaller packages.  For years, many industries have not had the expertise or resources to pursue custom chip designs, despite the fact that custom chips would bring a huge range of features in varying applications, such as harnessing the...
