Hello, Welcome to the Altium Learning Hub

With ever increasing speeds in high speed data systems comes a couple of PCB layout challenges. High speed busses like DDR, VME, PCIe just to mention a few can all reach data transfer speeds that require strict timing with very tight tolerances, thereby leaving very little slack in the PCB layout. Join us in this webinar to learn why it's imperative to match track lengths in high speed data systems and differential signals. You’ll see how to...

Routing PCB traces and vias on a PCB design is often thought of as a simple task. After importing the board and arranging components on the board, it would seem a relatively easy matter to start connecting components with copper. While that may have been true back in the days of low-speed TTL DIP components on simple boards, today’s design requirements are much more complex. Traces on a PCB can carry very specific design requirements that are...

I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of...

The primary source of high-speed problems is not due to high clock frequency but rather the fast rise and fall times of component signals. With fast edge rates, reflections may occur at the receiver side, and when the board routing is dense, crosstalk may become a problem. During this webinar, you'll sharpen your knowledge and develop new skills that you can use to design High-Speed PCB's more efficiently and effectively. We'll cover critical...

In electronics, there is the possibility that your PCB can get pretty hot due to power dissipation in certain components. Whenever a component reaches an extreme temperature that goes beyond a component's safe operating range, its lifetime will be greatly reduced or the component may fail immediately. The heat-producing component being defective means the entire PCBA will need to be scrapped. There are many things to consider when dealing with...

Every PCB needs to go through some level of evaluation before it can be placed into high-volume production. Designs will generally go through electrical testing during fabrication and assembly, but there are some specialized areas of mechanical and electrical behavior that are difficult to quantify during a test once the board is assembled. Instead of testing every aspect of a design, electrical circuit design simulation software can be used to...

Designing high speed channels on complex boards requires simulations, measurements on test boards, or both to ensure the design operates as you intend. Simulations can be used to generate predictions of signal behavior given a known input stimulus (pulse, bit sequence, or arbitrary waveform) using transforms and convolution operations. Unfortunately, it’s possible a simulation predicts behavior that doesn’t occur in reality due to incomplete...

Circuit simulations, signal simulations, and impulse response calculations often operate in an ideal world, where bandwidths aren’t limited or where singal artifacts aren’t observable in real measurements. Unfortunately, real interconnects and measurements are bandlimited, and this can create measurement artifacts that can create the appearance of a signal integrity problem like ground bounce, circulating reflection waves, or some level of...
