The Bare (Board) Truth by Mark Thompson

Mark Thompson has been in the industry for 29 years. He started out in Stockton, California in 1980 as a driller and photo tech right out of high school. He moved to Santa Clara soon thereafter, and worked for Multiplex (which became ACI West). In 1993 he relocated to the Pacific Northwest, where he worked for Pacific Circuits, (which became TTM) and Praegitzer Industries. He started working with Prototron in 1996, and has been with the company ever since.

This column – one of PCBDesign007’s most popular – covers design, layout and engineering practices as they relate to PCB fabrication. Not only signal integrity issues, but also topics such as eliminating unintentional co-planar coupling due to board real estate issues and defining the features on netlists to minimize mismatches.

In his free time, Mark is an avid pilot, with a fondness for the aircraft of yesteryear. Mark says, "I have been privileged to fly many biplanes from the 1930s and 1940s, including Fleets, Stearmans and N3Ns."
