https://spectrum.ieee.org/geek-life/hands-on/with-the-dead-bug-method-hobbyists-can-break-through-the-highfrequency-barrier PCBs are essential in mass-produced products. They assure almost perfectly repeatable circuits. And PCBs with a good ground plane are essential for high-frequency circuits. But rapid prototyping with PCBs has drawbacks compared with the speed and ease of building a circuit on a breadboard. This article presents one practical alternative to PCB for high-frequency →
