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...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]

Oh How I Hate to Commutate!
My favorite Sophomore in Engineering, Roger, and his group, made a small crane for their engineering project. It had many EMC issues. One issue they had was noise from permanent magnet DC motors. I am so glad Roger cares about this issue, because I have modeled a few permanent magnet DC motors, and I can explain how to design it so that then so they are … [Read more...]
