Megahertz [MHz]

In Part 1 of this two-part article, we’ll discuss the development of “grounding networks” and the shift to meshed structures to reduce damage from overvoltages. Part 2 will appear in our November 2020 issue.

CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.

If you’re performing commercial radiated and conducted emissions measurements strictly by the book, you will want to utilize a measurement receiver or spectrum analyzer that fully complies with CISPR 16-1-1.

If you’re an electrical engineer and consider proper EMC shielding a mechanical only issue, please reconsider your position and keep reading. Proper EMC shielding is both an electrical and mechanical design issue. Thoughtful coordination between the two disciplines is key to successful EMC shielding implementation on most product development projects.
