Houston Chapter of the IPC Designers Council Is pleased to present for
your educational benefit:
A Full Day Seminar
Controlled Impedance and RF/ Microwave by
Rick Hartley Applied Innovation, Inc. - Dublin, Ohio
Friday, October 12th, 2001
8: 00 AM to 5: 00 PM
Compaq Main Campus
20555 SH 249
Houston, Tx. 77070
281- 518- 6735

Process Engineers
Quality Control Personnel

RF and Microwave issues are inherent to High Frequency Analog PCBs. In
order to prevent circuit malfunction in these boards it is very
important that we understand the specific PCB design strategies needed
to harness these issues before problems develop.

RF / Microwave Topics
· Recommended Reading List.
· Basic Definition- RF verses Digital.
· Return Loss / VSWR.
· Inductance / Capacitance / Impedance.
· Current Return Path.
· Signal Wavelength / Signal Critical Length.
· Noise Sources and Control.
· Waveguide / Microstrip / Stripline / Coplanar Waveguide / CPW with
Ground.
· Microstrip verses Stripline, why one or the other?
· CPW and CPWG verses Microstrip.
· Impedance Calculations and Calculators.
· L, C and Signal Propagation Calculations.
· Integral Component Design.
· Integral Capacitors, Inductors, Filters and Couplers.
· Placement- Outputs verses Inputs.
· Component Relative Positions.
· Critical Trace Routing.
· Circuit Separation.
· Layer Pair Trace Routing.
· How Much "Ground"?
· Grounding Strategies.
· Trace Corners, Junctions and Vias.
· Circuit Tuning.
· Power Bus / Decoupling.
· Board Stack- up Strategies.
· Shields and Shielding.
· PCB Materials (Briefly).
· PCB Fab and Assembly (Very Briefly).

Controlled Impedance is becoming an important characteristic of high
speed printed circuit boards. As designers we must learn more about the
methodologies for calculating characteristic, oddmode and differential
impedances.

Controlled Impedance Topics
· Recommended Reading List.
· Why Control Impedance?
· Transmission Line Definition.
· Microstrip / Embedded Microstip / Stripline / Offset Stripline.
· Why 50 ohm? Why 75 ohms? Why and specific Impedance
· Controlled Impedance Calculators / Field Solvers
· Starting point for Layer Stack- ups and Line Widths.
· Changing Line Widths when you Change Layer.
· Effect of Adding Layers to a Controlled Impedance PCB.
· Trace Routing versus Termination Style.
· Power System Decoupling.
· Interfacing with the Fabricator.
· Notes needed on the Fabrication Drawing.
· Where to apply Tolerances in a Controlled Impedance PCB.
· Impedance Coupons and Testing.
· Cost Differential for Controlled Impedance

The Goal of this one day course is to provide a crisp focus on the
issues PC board designers and Engineers need to know and will offer a
clear under- standing of how to resolve Impedance and RF/ Microwave
problems.

About the Instructor. Rick Hartley is a senior PCB hardware engineer at
Applied Innovation, a provider of equipment to the telecommunications
and Internet access in- dustry. His background is in the design of
printed circuits for computers, aircraft avionics and
telecommunications. His first highspeed design was in 1979. He has
directed highspeed digital and RF circuit board design for the past 11
years. Hartley has an Associate EE degree and 35 years of experience in
the electronics industry. He has functioned as a technician and circuit
designer, dedicating the past 25 years to printed circuit design and
development with emphasis on control of signal integrity and EMI.
Hartley serves on the Editorial Review Board of Printed Circuit Design
Magazine, is chairman of the IPC Designers Council Executive Board and a
member of the Designers Council Education Committee; he is chairman of
the IPC Printed Circuit Design Committee and of the High Speed Focus
Module Committee. Additionally, he is co- founder and past president of
the Central Ohio Chapter of the IPC Designers Council.
