Continuing with this short series on high-speed signal integrity misconceptions, there is one formula that pops up again and again in elementary signal integrity discussions. This formula is the so-called knee frequency formula, and it is used interchangeably with some -3 dB frequency. What is interesting is that this is so often quoted as a value for the highest frequency contained in signal's bandwidth, which is not correct. Before even...

In this OnTrack episode, we are very excited to bring you Tim Wang Lee, a Signal Integrity Application Scientist and the High-Speed Digital Application Product Manager at Keysight. Tim will share his early days as a prodigy with Dr. Eric Bogatin. We will also discuss the importance of simulation and measurement to achieve signal integrity for your PCB design.

LCR meters measure inductance (L), capacitance (C), and resistance (R) – hence the name. LCR meters can be powerful tools for supporting the development of electronic circuits. However, to get the best from your meter, you must understand precisely how they work and the benefits they bring to the development process. In this article, we'll look at how LCR meters work, how to choose the best meter for your needs, and what benefits they can bring...

Conformal coating is a lightweight material applied to PCBs that acts as a protective layer. It protects circuit boards and components against various environmental factors, including heat, humidity, moisture, ultraviolet light, chemical contaminants, and abrasive materials. Conformal coatings also have thermal and electrical insulation properties to help manage your circuit's operating characteristics. The key benefit of applying a conformal...

There is one high-speed PCB design rule that has been over-communicated and misunderstood ever since its inception: the transmission line critical length rule. This rule is also known as the 25% rise time rule. The rule basically states conditions under which you don’t need to calculate trace impedance by stating: if the length of a trace is less than 25% of the distance traveled by a digital signal, then the trace impedance does not matter. ...

IPC continues to develop resources to bring awareness about the electronics industry to the young generation. In this episode, we are very fortunate to have Charlene Gunther, the Senior Director of the IPC Education Foundation. We will talk about IPC’s efforts to involve students in engaging activities that will introduce the electronic industry to them as early as high school. Join us and watch through the end. We added some great resources...

Enclosures are a vital part of an electronic project, though until recently, designing a bespoke case was an expensive and time-consuming process. However, advances in integrating Electrical Computer-Aided Design (ECAD) and Mechanical Computer-Aided Design (MCAD) packages make this simple. We'll demonstrate how easy it is in this article, where we will integrate SolidWorks MCAD with Altium Designer, thanks to the power of Altium's MCAD CoDesigner...

In the last article, How do I Get Started with my Altium 365 Component Library?, we walked through the basics of component creation with the Manufacturer Part Search (MPS) panel in the Altium 365 Workspace. Connections to Octopart and IHS Markit populate the component information of the MPS panel. However, manufacturers and suppliers generally provide the component models directly through their connections to the Octopart database creating...
