Hi Technetter,
Rick Hartley
I would like to attend this Seminar. Is there one coming to the San
Jose area in the near future.I would appreciate if you could give me
some leads here.

Topic: EMI & Crosstalk Control at the board level.
Rick Hartley - Applied Innovation
The Issue!
When a time-varying (AC) current flows in a wire or conductor, both an
electric field and a magnetic field are present. These fields are the
cause
of both EMI and Crosstalk. In recent years the effect of these fields has
increased in digital circuits due to increased device speeds (faster rise
and fall times). A device with a 1.0 nSec rising edge will likely have a
16
times greater EMI signature than a device with a 4.0 nSec rising edge.
The Solution!
There is no place in a circuit or system where we have better control of
these fields than at the PC board level. Gaining an understanding of what
generates these fields and how to control them and their effects will take
EMI and Crosstalk control from "guess work" to basic "everyday practice".
This 2+ hour presentation is a crisp and focused short course on the
issues
PC board designers and Engineers need to know to resolve EMI and
Crosstalk.
The topics include-
* Elements of EMI and Crosstalk.
* Circuit Properties - Frequency, Inductance, Capacitance and
Current
Paths.
* Why EMI and Crosstalk are on the Rise.
* Differential and Common Mode EMI.
* Proper Power Distribution and Decoupling.
* Techniques to Control EMI and Crosstalk.
* Size and Position of Power Planes.
* Type and Location of Components.
* Signal Routing Techniques.
* PC board layer structuring (Board Stack).
* Grounding Techniques.
