How Bad are Swiss Cheese Planes?

Holey Swiss cheese offers a popular metaphor for describing planes with a high density of clearance holes, usually under a BGA escape. The concern of many designers is the impact on the inductance in the power and ground planes due to all those holes. Since the gaps between them is narrow, won’t they constrict the current, dramatically increasing the series resistance and the loop inductance of the planes?

Get it Right the Second Time

We all strive to, “Get it right the first time,” in our designs, and focus on skills, techniques and tools to help us achieve this. But we should also pay attention to the skills, techniques and tools to “Get it right the second time.” This is a phrase Dave Graef, CTO and General Manager of Teledyne LeCroy likes to use.

My Visit to the EMI Test Lab - Part of the Fun of Science

Last week, I had the chance to visit with Dennis King at his EMI Test Lab in Longmont, Colorado. While Dennis has been doing EMI testing for more than 30 years, he set up his independent test lab in 2004. With a GTEM and 3-m anechoic chamber, plus stations for ESD and susceptibility testing, he routinely performs testing for CE Mark and FCC emissions and immunity requirements.
