Just Ask Happy: Ground Reference Planes
June 29, 2020 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute

We asked for you to send in your questions for Happy Holden, and you took us up on it! The questions you've posed run the gamut, covering technology, the worldwide fab market, and everything in between. Enjoy.
Q: How important are GND reference planes in signals that are less than 50MHz, since 1/4 wavelength is about 30 inches?
A: GND is an essential part of the circuit. The return path for DC is the lowest resistance, but for the AC part of the signal, it is the lowest inductance.
Take the survey to pose your own question for Happy Holden.

Direct Metallization: A Sustainable Shift in PCB Fabrication
07/31/2025 | Jim Watkowski, Harry Yang, and Mark Edwards, MacDermid Alpha Electronics SolutionsThe global electronics industry is undergoing a significant transformation, driven by the need for more resilient supply chains and environmentally sustainable manufacturing practices. Printed circuit boards (PCBs), the backbone of interconnection for electronic devices, are at the center of this shift. Traditionally, PCB fabrication has relied heavily on electroless copper, a process that, while effective, is resource-intensive and environmentally hazardous. In response, many manufacturers are turning to direct metallization technologies as a cleaner, more efficient alternative.
