SDDC Meetings and Events -YOU ARE INVITED TO ATTEND-
San Diego Chapter of the IPC Designers Council is pleased to present the
following:

                Wednesday, Jan 25th, 2005 @ 6:00PM
                        Rick Norfolk
                                of
                        Hallmark Circuits
                          Presenting:

"Controlled Impedance, from the Fabricator's Point-of-View"

 MARK YOUR CALENDAR!!!

                ***

   The presentation will briefly cover what various types of impedances
exist. Mostly the presentation will cover cores/preg material and how they
interlink with the finished line width to get the impedance value desired by
the OEM. We will cover 'loss to fill ratios' within a board stack-up and how
this affects the impedance values and how the percentage of copper of a
particular layer is important in determining the dielectric thickness to the
reference planes of the various impedance types.

 This presentation will help designers better understand what is involved
from a fabricator's standpoint in meeting the required impedance values of a
design and the importance of working with a fabricator during the design
phase.

Poway, California. Rick has been working in the printed circuit industry for
approximately 28 years. He started his career at TRW, Printed Circuits
Division (later becoming Benchmark Technology) as a planner. Rick was a
Planning Engineer at Sigma Circuits for 7 years. He worked for 5 years as a
Product Engineer at Hadco/Sanmina in Owego, New York and there he worked
with OEM designers on fabrication and design issues and specialized in
controlled impedance applications.

Rick has been an Applications Engineer with Hallmark Circuits now for almost
5 years. He routinely provides guidance to their customers in board material
and board layer stack-up recommendations for controlled impedance designs.
Rick has made several presentations to Hallmark's customers and fabricators
