The Composite Properties of
Rigid vs. Multilayer PCBs
Data sheets often provide data in iPC formats,
which may look at properties in rigid laminates
rather than thin lams and prepregs used for multi-
layer PwBs. Plus, some product lines are manufac-
tured with consistent resin content for all product
thicknesses, thus maintaining dielectric properties
while letting the mechanical properties be dictat-
ed by the constructions and resin content.

ICD Releases 2015 Version
of the ICD Stackup and
PDN Planner
in-Circuit Design Pty Ltd (iCD), australia, develop-
er of the iCD Stackup and PDn Planner software,
has released the 2015 version of their popular soft-
ware. "The impedance plots are simulated by mul-
tiple passes of the field solver (in the background)
to create heads-up graphs of how to adjust the
particular variables to achieve the target imped-
ance," said Barry olney, Ceo.
