Flexible circuit applications
can be as basic as furnishing
electrical interconnect between
two conventional circuit board
assemblies, or to provide a
platform for placing and inter-
connecting electronic compo-
nents. During the planning and
pre-design phase of the flexible circuit, there will be several material and process related
questions that need to be addressed.
With more of us working to gain board layout experience on the job, Designing for
Reality becomes a very pertinent discussion topic in the PCB industry. But what
does that phrase even mean and why should we focus on such a topic?

EDA 2024, a
tightly integrated
suite of electronic
design automa-
tion (EDA) soft-
ware tools that
ensures first pass success. This new integrated
EDA software facilitates a "shift left" approach to
increase productivity for engineers developing
high speed, high frequency products in multiple
applications.
Another challenge for SerDes is losses
within the channel design. At high
speeds, dielectric material can be very
lossy, making the appropriate selection
of the right material, length, etc., critical
for the channel. Many questions about
stackup, trace widths, and height from
the ground plane need to be defined
up front.
