Lightning Speed Laminates: Things
to Consider When Creating a
Circuit Material Library
E
A circuit material library for
the fabricator can be advan-
tageous for multiple reasons.
Sometimes these libraries are
intended to be used for electri-
cal predictions, such as imped-
ance, insertion loss or other issues. Other times
the information found in the circuit material
libraries are used to assist with thermal issues,
potential reliability concerns, circuit construc-
tion stackups and some processing issues.

Footprints: A Distributor's
Perspective
E
No issue on footprints and library
management would be com-
plete without input from a com-
ponent distributor. I recently
interviewed Geof Lipman of
Octopart; as director of opera-
tions for part data, he's one of the brains behind
the entire site. Geof explains how Octopart
functions and manages millions of component
data points, and he also discusses the current
landscape of electronic components.

Customers Experience Speed
Increases of up to 80% on PCB
Designs Using Pulsonix 11.0
E
Pulsonix has announced the release of Pulso-
nix version 11.0, which offers significant speed
improvements by using the latest technologies
available, as well as the introduction of new
functionality for high-speed designs.

Beyond Design: Stackup Planning—
Three Decades of Innovation
E
Materials used for the fabri-
cation of multilayer PCBs,
absorb high frequencies and
reduce edge rates thus putting
the materials selection process
under tighter scrutiny. Ensur-
ing that your board's stackup and impedances
are correctly configured is a good basis for sta-
ble product performance.

Seven Tips for Your Next
Stackup Design
E
Rarely do we have the luxury of
designing a board just for con-
nectivity. When interconnects
are not transparent, we must
engineer them to reduce the
noise they can generate. is is
where design for signal integrity, power integ-
rity and EMC—collectively high-speed digital
engineering—are so important. Eric Bogatin
offers seven tips for stackup design.
