Speeding Edge offers several training courses intended to introduce new
engineers to the issues related to successfully designing high speed electronic
systems. These courses also serve to update the skills of practicing engineers
who are confronted with the rapidly changing world of high speed electronics
involved in products ranging from disc drives to terabit routers and
supercomputers.
All of these courses are available as private on site courses. Occasionally,
these courses are offered as public courses. The public offerings are posted on
the Speeding Edge web site and announced through various media. The full
description of each course follows below this list.
ONE DAY COURSES
Speeding Edge offers two one day courses intended to upgrade skills in
specific areas. These are:
Power Delivery System Design
PCB Stackup Design- Optimizing Signal Integrity, Manufacturability and
Reliability of a Printed Circuit Board
TWO DAY COURSES
Signal Integrity and High Speed System Design
THREE DAY COURSES
Signal Integrity and High Speed System Design- extended version
One-Day Power Delivery System Design Class:
Speeding Edge is now offering a one-day power delivery system (PDS) design
class as an on-site class. Today´s high-speed designs use a variety of power
delivery components and successfully designing a PDS and the PCB into which is
incorporated requires a thorough understanding of the overall power delivery
system. In addition to reviewing the PDS components currently available; this
course examines how to meet the conflicting goals of the PDS system and how to
address power plane, impedance and overall system capacitance issues.

PCB Stack Up Design to Optimize Material Selection and Fabrication
Techniques for Manufacturability, Reliability and Signal Integrity
Successful fabrication of any PCB starts with selecting the right laminate
materials and creating a stackup design that works. Today’s high-speed PCBs
with their inherent signal integrity and power delivery requirements make it
necessary to employ far more discipline in the choice of materials and the
arrangement of layers in the stackup. For more information, follow this
link.
Two-Day Signal Integrity and High Speed System Design
Course
This comprehensive two-day course from High Speed Design´s "Ratchet Man" covers all key aspects
of the high speed design process. If you can take only one course on this
subject, this is the one for you.

*Denotes on-site courses
Here is a sampling of some of the comments from students who attended these
courses: "The principals taught and 'tools' learned in the High Speed Design
course have proved very beneficial, enabling me to use a more thorough
engineering approach to PCB layout." Larry Hewitt, PCB Design
Engineer, JTS Corporation "Lee Ritchey's course was the turning point in
my understanding capacitance and EMI. I highly recommend this course to
engineers and CAD designers who want to pass EMI tests with ample margins."

PCB Stack Up Design to Optimize Material Selection and Fabrication
Techniques for Manufacturability, Reliability and Signal Integrity
Successful fabrication of any PCB starts with selecting the right laminate
materials and creating a stackup design that works. Today’s high-speed PCBs
with their inherent signal integrity and power delivery requirements make it
necessary to employ far more discipline in the choice of materials and the
arrangement of layers in the stackup. These requirements are outside the skill
set of all PCB fabricators. The objective of this course is to guide the design
engineer through the process of evaluating and selecting the right laminate for
any given design and then designing a PCB stackup that meets the numerous
demands of a complex, multilayer board that works right the first time. The
first portion of this class consists of a one-hour session conducted by Isola
Group.Topics that will be addressed include the building blocks available for
core and prepeg materials; the impact of material selection; an overview of
available materials; what designers should be looking for during the evaluation
and selection process and a short tutorial on Isostack, a new web-based stackup
tool. and how they are used in various design implementations and what
designers should be looking for during the evaluation and selection process.
The second portion of the class, which delves more into the role of laminates
in high-speed PCBs as well as how to create a successful stackup design, is
conducted by Lee Ritchey. Founder and president of Speeding Edge, he is
considered to be one of the industry’s premier authorities on the design and
manufacture of high-speed PCB systems. The fast data paths that are pervasive
in all PCB products being currently designed make it imperative to be able to
design stackups that have predictable and repeatable impedances.
The demands addressed in this portion of the course include:
- Providing enough signal layers to allow successful routing
of all signals to signal integrity rules.
- Copper thickness in planes and signal layers that meets the
conductivity demands of signals and power, and at the same
time, be reasonable to manufacture.
- Accounting for copper roughness and its affect on overall
signal path loss.
- Specifying glass weave styles to minimize differential
signal skew.
- Dealing with the combined loss from both the dielectric and
the copper loss to arrive at an effective loss tangent that
accurately predicts overall path losses.
- Specifying copper surface roughness to ensure repeatable
loss from lot to lot and fabricator to fabricator.
- Show how to document a stackup to ensure all design goals
are met with finished PCBs.
|
- Providing enough power and ground layers to meet the needs
of the power delivery system.
- Determining dimension trade widths and dielectric
thicknesses that allow impedance targets to be met.
- Ensuring that the spacing between signal layers and their
adjacent planes is thin enough to satisfy cross talk
needs.
- Specifying dielectric materials that are economical to
manufacture and are readily available.
- Avoiding the use of expensive techniques such as blind and
buried vias and build up processing if possible.
- Providing for prototyping manufacture in one factory or
country and production manufacture in another factory or
country.
|
The following topic areas will be covered in this portion of the course:
- How a typical multilayer PCB is built.
- Alternative PCB Fabrication Methods.
- Choosing a fabricator as a design partner.
- Types of signal layers.
- Alternate ways to stack layers.
- Selecting an impedance.
- Making all signal layers the same impedance.
- Selecting laminates.
