Medical, Defense Face Shortage of
Multilayer Ceramic Capacitors
E
Industrial, medical, and mili-
tary demand for high-quality,
high-voltage multilayer ceramic
capacitors (MLCCs) has been
hit hard by a shi in production
by the world's largest MLCC
manufacturers who are focusing on a seemingly
insatiable demand for smaller, lower voltage—
and in some way—lower-performance MLCCs.

Hate PCB Respins? Five Ways to
Reduce or Eliminate Respins
E
Redesigning a printed circuit
board is a chore that no one
likes. Respins of printed circuit
boards cost money, delay the
schedule, and just aren't enjoy-
able for anyone. Yet, many com-
panies are not taking advantage
of available tools that can reduce—and in many
cases eliminate—PCB respins.

Why We Simulate E
When Bill Hargin was cutting his
teeth in high-speed PCB design
some 25 years ago, speeds were
slow, layer counts were low,
dielectric constants and loss
tangents were high, design mar-
gins were wide, copper roughness didn't matter,
and glass-weave styles didn't matter. Dielectrics
were called "FR-4" and their properties didn't
matter much. A fast PCI bus operated at just 66
MHz. Times have certainly changed.

PCB Design Challenges:
Designing With DDR
E
Longtime signal integrity experts Rick Hartley
and Barry Olney join the I-Connect007 edito-
rial team for a discussion around DDR and the
complications board designers inevitably face
when they design for DDR. If the DDR design
process is not that much more complicated than
that of a typical high-speed board, why does
DDR cause design engineers so much grief ?
