Cable Discharge Event (CDE)
Abstract Worst-case Cable Discharge Events (CDE) are poorly understood by most of the product developers as the definition of what is about to happen when you plug in a cable into an appliance’s socket. It is NOT the electro-static charge which could be expected on the cable: outer/inner shield(s) + internal wires, while the cable is fully floating prior to the cable … [Read more...]
Conformal Conductive Coating and EMI Shielding
This is a diverse and promising space. In one manifestation, spray-on inks are targeting package-level EMI shielding. Here, they hope to displace sputtering, the incumbent, which benefits from sunk CapEx and lower material consumption costs. They offer low CapEx production in atmospheric conditions and better conformal coverage. Others are developing inkjet printing solutions, … [Read more...]
Review of MIL-STD-464 Requirements
Introduction My reviews have covered MIL-STD-461 over the past few months so it’s time to step up to the system requirements. We realize that the MIL-STD-461 requirements apply to equipment items and subsystems as stated in MIL-STD-464. Revision “C” is the current edition, but a review is a little overdue. In this review, the discussion will focus on the various requirements … [Read more...]

This symposium is sponsored by the IEEE EMC Society (EMC-S), the world's largest organization dedicated to the development and distribution of information, tools and techniques for reducing electromagnetic interference with support … [Read more...]
Review of MIL-STD-461 General Requirements
Introduction Recently I noted that my series on MIL-STD-461 test methods was closing since I had accomplished a review on each of the test methods. It seems appropriate to continue with a review of General Requirements – those things common to the various test methods. These requirements have been around since the first release of MIL-STD-461 and MIL-STD-462 dealing with … [Read more...]
