Designing Proper Planes
Without planes, designers would have to create thousands of traces to accomplish the same objectives. Power planes provide low impedance and stable power, and ground planes stabilize reference voltage, improve thermal performance, and help preclude EMI issues.
Power Integrity
Current power demands are increasing, especially with AI, 5G, and EV chips. This month, our experts share “watt’s up” with power integrity, from planning and layout through measurement and manufacturing.
Signal Integrity
If you don’t have signal integrity problems now, you will eventually. This month, our expert contributors share a variety of SI techniques that can help designers avoid ground bounce, crosstalk, parasitic issues, and much more.

Freedom CAD Celebrates 15th Anniversary
May 15, 2018 | Freedom CADEstimated reading time: 1 minute
May 16, 2018 marks the 15th anniversary of Freedom CAD Services. Freedom CAD was founded on this day by Lou and Lauren Primmer, pioneers in the PCB CAD industry. They launched Freedom CAD when Plexus decided to divest the Nashua, NH design center in 2003.
The Primmers formed Freedom CAD with 11 other ex-Plexus employees to service a number of long time regional customers. Since then, Freedom CAD has grown to become one of the largest independent design services companies in North America.
Over the past 15 years they have more than tripled their staff of topnotch designers and now have designers working across the US. In addition to supporting Cadence Allegro, Mentor’s Xpedition and PADS and Altium PCB CAD tools, Freedom CAD also provides PCB electrical and mechanical engineering services, signal and power integrity analysis and prototype fulfillment services.
“In 2003, we had a vision to create the highest quality independent printed circuit board design service company in the country,” said Lou Primmer. “We believed we could leverage our ‘structured, large corporation’ experience and create a nimble, privately held company. I’m pleased to say that we were successful at accomplishing this and the fact that we are ITAR-registered and ISO9001-certified, both of which require structure and process control, are indicators of this accomplishment. And during this time we have leveraged this structure and nimbleness to expand our customer base from regional to national and include many of the Fortune 100 Electronics OEMs. I’m proud to see the vision become a reality and look forward to the next 15 years!”
