Parasitic Extraction with an Electromagnetic Solver in PCB Routing
Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms. There are many 3rd party applications that can be

A Guide to Mode Conversion, Its Causes, and Solutions
Differential pairs are most often discussed in terms of their impedance and length matching tolerance, both with the goal of ensuring proper termination at the receiver and suppression of common mode noise. On interconnects, such as board-to-board connections or cascaded transmission line arrangements, you have an important EMC compliance metric that is sometimes overlooked. This is mode conversion, which can be visualized in an S-parameter

PCB Via Current-Carrying Capacity: Is My PCB Too Hot?
What does PCBA too hot mean? It's a common question from designers, particularly new designers that are learning about industry standards, and refers to the PCB via current-carrying capacity of conductors. Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components
