Current IssueVoices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.
The Essential Guide to Surface Finishes
We go back to basics this month with a recount of a little history, and look forward to addressing the many challenges that high density, high frequency, adhesion, SI, and corrosion concerns for harsh environments bring to the fore. We compare and contrast surface finishes by type and application, take a hard look at the many iterations of gold plating, and address palladium as a surface finish.
It's Show Time!
In this month’s issue of PCB007 Magazine we reimagine the possibilities featuring stories all about IPC APEX EXPO 2025—covering what to look forward to, and what you don’t want to miss.

RF PCB Design Tips and Tricks
05/08/2025 | Cherie Litson, EPTAC MIT CID/CID+There are many great books, videos, and information online about designing PCBs for RF circuits. A few of my favorite RF sources are Hans Rosenberg, Stephen Chavez, and Rick Hartley, but there are many more. These PCB design engineers have a very good perspective on what it takes to take an RF design from schematic concept to PCB layout.

The Right Blend: Mixed Wireless Technologies
05/08/2025 | Kirsten Zima, Siemens EDAA common trend recently is to employ as many radios as possible on a single PCB. With the increase of wireless standards and the downscaling of PCB size, it can be difficult to know what the most critical design parameters are to focus on. In this article, we’ll discuss the most important considerations to make when designing with mixed wireless technologies, such as Bluetooth, GPS, and Wi-Fi, on a single PCB. These considerations include antennas, frequencies, FCC compliance, shielding, and layout with and without transition vias.
