EMI and EMC are two areas where PCB designers have an important role to play. The PCB designer’s job is to ensure a design is laid out such that noise generation is below regulatory limits. Many systems that are initially designed to be perfectly functional will not pass regulatory standards due to particular practices in the PCB layout. It then becomes the PCB designer’s job to modify a PCB layout to ensure it passes regulatory standards. To...

Happy Holden, a legend in the PCB Industry and one of our favorite Altium Industry Expert contributors gives us a trip to his 53 years of experience in the industry.

When designing we don’t start from scratch every time we need to create a design, we reuse what we’ve already done. Reusing common circuitry is a great way to get a head start on your project and speed up development. This webinar we’ll take a deeper dive into design reuse blocks and discuss some practical recommendations to effectively use them in your designs. We’ll go over: How to create a new reuse block. Placement of a reuse block in...

Impedance control, impedance management, and controlled dielectric are three terms that are loosely interchangeable and refer to different methods for setting the impedance seen by signals in a PCB. Impedance calculation tools, such as free online tools and your EDA programs, can help you calculate trace impedance and you can get a very nearly accurate value for impedance. However, the rubber meets the road during manufacturing, and the design...

Trace resistance, trace impedance, plane resistance, and plane impedace: when do you need to worry about all of these quantities? Resistance and impedance both are important in small traces and fat rails on a PCB, both internally and externally. Sometimes a new designer entering the world of impedance controlled buses might think they have a trace resistance target, when really they have a trace impedance target. While in power electronics, we...
