Lightning Speed Laminates: Test
Vehicles for Materials Evaluation
E
There are many different
types of PCB designs and
constructions that can be
used as a test vehicle to
evaluate electrical proper-
ties. John Coonrod explains
how a proper test vehicle to
compare different circuit materials would be
a design and construction that takes into con-
sideration the different material properties and
have the least amount of PCB fabrication vari-
ables that can impact the results.

Mentor Paper: Concepts of Signal
Integrity—Impedance
E
Successful signal integrity analysis depends on
a fundamental concept: impedance. Without a
thorough understanding of the impedance val-
ues that a signal encounters along the way, de-
signers cannot maintain good signal quality
from source to receiver. This Mentor paper de-
fines the difference between characteristic and
instantaneous impedance and explores the es-
sential principles of impedance and design-
controlled impedance.

The Digital Layout:
Fall 2019 Recap
E
As the second half of the year
is quickly passing by, the IPC
Designers Council has seen
lots of continued activities
within our industry regard-
ing PCB design. PCB West
was held in mid-September
in Santa Clara, California,
and as usual, the show exceeded expectations.
Stephen Chavez provides a brief breakdown of
fall activities within local chapters.
